It handles various tasks such as setting up UI elements, loading data, and initializing the messenger functionality. + +#### Usage + +```javascript +onLoadStartUp(); +``` + +### Description +This function performs the following steps: +- Route to Loading Page: Redirects the user to the loading page and removes the hidden class from the body element. +- Set Custom Private Key Input: Configures a custom private key input handler for user sign-in. +- Append Emoji Picker Styles: Appends styles for the emoji picker to the shadow root of the emoji picker element. +- Launch Startup Sequence: Invokes the startup functions using floDapps.launchStartUp(). This includes setting user IDs, rendering UI elements, initializing messenger functionalities, and checking for available background images. +- Error Handling: Catches and handles errors that might occur during the startup process. Displays appropriate notifications for specific error cases. + +### Related Functions +- `routeTo(page, options)`: Handles client-side navigation to different pages within the application. +- `getSignedIn()`: Handles the user sign-in process. +- `setBgImage()`: Checks for and sets the background image for the application interface. +- `messenger.init()`: Initializes the messenger functionality and renders chat messages and other UI elements. + + +## `routeTo(targetPage, options = {})` + +This JavaScript function, routeTo(targetPage, options = {}), is an asynchronous function that is used for handling client-side navigation in a web application. It takes two parameters: targetPage, which represents the page to navigate to, and an optional options object with various configuration settings. The function performs different actions based on the specified targetPage and updates the application state and UI accordingly. + +### Function Signature +```javascript +async function routeTo(targetPage, options = {}) { + // function body +} +``` + +### Parameters +- `targetPage`: A string representing the page to navigate to. +- `options`: An object containing configuration settings. In the function, only the firstLoad property is extracted from this object. + +### Function Logic +- Page Identification: The function first checks the targetPage. If it's an empty string, it determines the appropriate pageId based on the user's status (if the user is logged in, it sets pageId to 'chat_page'; otherwise, it sets it to 'landing'). + +- Parsing Target Page: If targetPage is not empty, the function checks if it contains a slash (/). If it does, it splits the targetPage into parts (pageId, subPageId1, and subPageId2). If there is no slash, pageId is set to targetPage. + +- Validation and State Updates: The function validates the pageId and updates the application state (appState.currentPage) accordingly. Depending on the pageId, different actions are taken: + +1. For 'sign_in' page, it focuses on a specific input field. +2. For 'sign_up' page, it generates keys. +3. For 'chat_page', it handles various cases related to chat messages and notifications. +4. For 'mail_page', it handles different mailbox sections. +5. For 'settings', it shows specific panels based on subpage identifiers. +6. For other pages, no specific actions are taken. + +- Navigation and UI Updates: The function updates the browser history (history.replaceState) and animates UI elements based on the page transitions. It also handles the visibility of different UI components based on the current page. + +- Intersection Observer: There is an IntersectionObserver named indicatorObserver that observes elements and performs animations based on their visibility in the viewport. + +### Notes: +- The function uses asynchronous code (await keyword) for handling certain tasks, indicating that it can perform asynchronous operations. +- The function relies on various utility functions (getRef, createElement, showChildElement, etc.) These functions are assumed to be part of the application's codebase and are used for DOM manipulation and UI interactions. + + +## `class LazyLoader` +This class is designed to efficiently handle lazy loading of elements in a web application, meaning it loads elements (such as images or other content) only when they become visible to the user. Let me break down the class and its functionality step by step: + + +### Class Properties: +- container: Represents the HTML element inside which the lazy-loaded content will be placed. +- elementsToRender: A function or an array representing the elements to be lazy-loaded. +- renderFn: A function responsible for rendering individual elements. +- options: An object containing optional configuration settings like batchSize, freshRender, bottomFirst, and onEnd. + +### Class Methods: +- init(): Initializes the lazy loading functionality. It sets up IntersectionObserver and MutationObserver to handle element visibility and DOM changes. +- update(elementsToRender): Updates the array of elements to be lazy-loaded. +- render(options): Renders the elements based on visibility or user scrolling. It calculates the visible range of elements and renders them. +- clear(): Disconnects the IntersectionObserver and MutationObserver and clears the container's content. +- reset(): Resets the LazyLoader by reinitializing the array of elements and rendering them. + +### Class Workflow: +- Initialization (init()): When init() is called, the class sets up an IntersectionObserver to detect when elements come into view and a MutationObserver to watch for changes in the DOM. These observers work together to handle lazy loading efficiently. + +- Updating Elements (update(elementsToRender)): The update() method allows dynamically updating the elements that need to be lazy-loaded. It takes a new set of elements and updates the internal array. + +- Rendering Elements (render(options)): The render() method calculates the range of elements to render based on scrolling or visibility. It then calls the provided renderFn for each element in the calculated range, creating the DOM elements and appending them inside the specified container. If the lazy loading is triggered due to scrolling, it adjusts the scroll position to ensure smooth loading. + +- Clearing (clear()): The clear() method disconnects the observers and clears the content of the specified container. It's useful when you want to remove the lazy-loaded content from the DOM. + +- Resetting (reset()): The reset() method resets the LazyLoader by reinitializing the array of elements and rendering them again from scratch. + +## `getRef(elementId)` +This JavaScript function, getRef(elementId), is a custom utility function designed to improve the efficiency of accessing DOM elements by their IDs. It provides a way to cache references to DOM elements and reuse them, reducing the number of times the actual DOM is queried. + +### Parameters: +`elementId:` The ID of the DOM element that you want to retrieve. + +### Function Logic: +- The function checks if the `elementId` is present in the `domRefs` object. `domRefs` is an external object that serves as a cache for DOM elements. +- If the `elementId` is not present in `domRefs`, a new entry is created for it. This entry contains a count property initialized to 1 (indicating that the element has been accessed once) and a ref property initialized to null. +- If the `elementId` is already in `domRefs`, the function checks the count property: +- If the count is less than 3, it means the element has been accessed less than 3 times. In this case, the count is incremented, and the function returns the element obtained through `document.getElementById(elementId)`. +- If the count is 3 or more, it means the element has been accessed 3 or more times. In this case, the function checks if the ref property is null. If ref is null, it means the DOM element reference hasn't been cached yet. The function then retrieves the element using `document.getElementById(elementId)`, assigns it to `domRefs[elementId].ref`, and returns the cached reference. I +- If ref is not null, it directly returns the cached reference without querying the DOM again. + +### Caching Mechanism: +- The function caches DOM element references in the domRefs object to avoid redundant DOM queries. This caching mechanism helps improve the performance of the application, especially in cases where the same element is accessed multiple times. +### Usage Example: +- Instead of using `document.getElementById(elementId)` directly in the code, developers can use `getRef(elementId)` to access the DOM elements. The function takes care of efficient element retrieval and caching. + +## `debounce(callback, wait)` + +Debouncing is a technique used in web development to ensure that time-consuming tasks (such as API requests or UI updates) are executed only after the user has finished making changes, rather than triggering the task every time an event fires. + +### Function Parameters: + +- **callback**: The function that needs to be executed after the user finishes making changes. This function is passed as the first parameter to `debounce`. +- **wait**: The number of milliseconds to wait after the last invocation of the debounced function before executing `callback`. + +### Function Logic: + +#### Initialization: + +The `debounce` function returns an anonymous function that takes any number of arguments `(...args)`. + +#### Timeout Management: + +1. **Clear Existing Timeout**: + - When the debounced function is called, it first clears any existing timeout by calling `window.clearTimeout(timeoutId)`. This ensures that the execution of the debounced function is reset every time the debounced function is called within the specified `wait` period. + +2. **Set New Timeout**: + - Then, it sets a new timeout using `window.setTimeout(() => { /* callback execution */ }, wait)`. This new timeout will only execute after `wait` milliseconds have passed since the last invocation of the debounced function. + +3. **Callback Execution**: + - Inside the timeout function, the original `callback` function is executed using `callback.apply(null, args)`, where `args` contains the arguments passed to the debounced function. + +### Usage Example: + +```javascript +const debouncedFunction = debounce((arg) => { + console.log(`Debounced function called with argument: ${arg}`); +}, 1000); + +debouncedFunction("First call"); // This will not execute immediately +debouncedFunction("Second call"); // This will not execute immediately +// After 1000ms (1 second), the debounced function will execute with the last provided argument ("Second call") +``` + +## `getLastMessage(floID)` + +The `getLastMessage` function is an asynchronous function that retrieves the last message from a conversation specified by the provided `floID`. + +### Function Signature + +```javascript +function getLastMessage(floID: string): Promise +```` +### Parameters +`floID`: A string representing the unique identifier of the conversation (chat or group) from which to retrieve the last message. +### Returns +A Promise that resolves to an object containing information about the last message in the specified conversation. The object has the following properties: + +- message: The content of the last message. +- time: The timestamp of the last message. +- sender: The sender's ID of the last message. +- category: The category of the last message (e.g., 'sent', 'received'). +- lastText: A formatted string representing the last message for display purposes. + +### Function Logic +The function determines the type of conversation (chat or group) based on the provided floID. +- It retrieves the last message from the conversation using messenger.getChat(floID). +- If the conversation is a group and the last message has a timestamp of 0, it means the group was just created. In this case, the group creation time is used as the last message time. +- The function formats the last message for display purposes, adding sender information (or 'You' for sent messages) and handling blocked conversations appropriately. +- The formatted last message object is returned in the resolved Promise. + +## `delegate` Function Explanation + +The `delegate` function is a utility function in JavaScript used to implement event delegation. Event delegation is a technique where a single event listener is attached to a common ancestor element of multiple child elements. Instead of attaching event listeners to each child element individually, event delegation allows you to handle events for all child elements in a more efficient manner. When an event occurs, it bubbles up from the target element to the ancestor element, where the event listener is placed. The `delegate` function facilitates this pattern. + +### Function Parameters: +- `el`: The common ancestor element to which the event listener is attached. +- `event`: The type of event (e.g., "click", "mouseover", etc.) to listen for. +- `selector`: A CSS selector string specifying the child elements for which the event should be delegated. +- `fn`: The callback function to be executed when the event occurs on a matching child element. + +### Function Logic: +1. The `delegate` function takes in the ancestor element `el`, the event type `event`, the CSS selector `selector` for child elements, and the callback function `fn`. + +2. It attaches an event listener to the ancestor element (`el`) for the specified event type (`event`). + +3. When the event occurs on any descendant element of `el`, the event object (`e`) is passed to the event listener function. + +4. Inside the event listener function, `e.target` represents the element on which the event actually occurred. The `closest` method is used to find the closest ancestor of the target element that matches the specified `selector`. + +5. If a matching ancestor element is found (`potentialTarget`), the `delegateTarget` property is added to the event object (`e`). This property refers to the ancestor element that matches the specified selector. + +6. The callback function `fn` is then executed in the context of the ancestor element (`this`). The event object (`e`) is passed to the callback function, allowing you to handle the event on the matching child element. + +## `getFloIdType` Function + +The `getFloIdType` function is used to determine the type of a given FLO ID in the context of the messenger application. It checks whether the provided FLO ID belongs to a group, a pipeline, or if it is a plain individual FLO ID. + +### Function Parameters: +- `floID`: The FLO ID for which the type needs to be determined. + +### Return Value: +- `'group'`: If the provided FLO ID belongs to a group. +- `'pipeline'`: If the provided FLO ID belongs to a pipeline. +- `'plain'`: If the provided FLO ID is an individual, not associated with a group or pipeline. + +### Function Logic: +1. The `getFloIdType` function takes in a `floID` as a parameter. + +2. It checks if the `floID` exists in the `messenger.groups` object. If it does, the function determines that the `floID` belongs to a group and returns `'group'`. + +3. If the `floID` is not found in `messenger.groups`, the function checks if it exists in the `messenger.pipeline` object. If found, it indicates that the `floID` belongs to a pipeline and returns `'pipeline'`. + +4. If the `floID` is not found in either `messenger.groups` or `messenger.pipeline`, the function concludes that it is a plain individual FLO ID and returns `'plain'`. + +## `renderDirectUI(data)` + +The JavaScript function `renderDirectUI(data)` is designed to handle the rendering of direct messages and mails in a user interface. This function plays a crucial role in updating the UI and providing notifications to the user based on new messages and mails, ensuring a responsive and interactive user experience. + +### Parameters +- `data`: An object containing messages and mails data to be rendered in the UI. + +### Function Logic +1. **New Message Notifications:** + - If there are new messages in the `data.messages` object and the last visited page is not 'chat_page', it updates the document title to indicate the presence of new messages and adds a notification badge to the 'chat_page_button'. + +2. **New Mail Notifications:** + - If there are new mails in the `data.mails` object and the last visited page is not 'mail_page', it updates the document title to indicate the presence of new mails and adds a notification badge to the 'mail_page_button'. + +3. **Notification Panel Updates:** + - It queries the server for uncompleted requests (`messenger.list_request_received({ completed: false })`) and updates the notification badge on the 'notification_panel_button' based on the number of pending requests. + +4. **Message UI and Mail List Rendering:** + - It calls the `updateMessageUI(data.messages)` function to update the UI with new messages. + - It calls the `renderMailList(data.mails, true)` function to render the mail list, passing `true` as a parameter to indicate that these are new mails. + +### Usage Example: +```javascript +// Example usage of the renderDirectUI function +const data = { + messages: { /* ... */ }, // New messages data + mails: { /* ... */ } // New mails data +}; +renderDirectUI(data); +``` + +## `renderMailList(mails, markUnread = true)` + +The JavaScript function `renderMailList(mails, markUnread = true)` is responsible for rendering mail items into the user interface. This function dynamically updates the mail interface, ensuring that mails are displayed in the inbox and sent mail categories. + +### Parameters +- `mails`: An object containing mail data to be rendered in the UI. +- `markUnread` (optional, default: `true`): A boolean indicating whether unread mails should be marked. + +### Function Logic +1. **Initialization:** + - It initializes two DocumentFragments, `inboxMails` and `sentMails`, to store the rendered mail items for inbox and sent mail categories respectively. + - Variables `inboxCount` and `sentCount` are initialized to keep track of the number of unread mails in each category. + +2. **Mail Iteration and Rendering:** + - It iterates through the provided `mails` object and extracts mail details such as sender (`from`), receiver (`to`), subject, time, and content. + - Depending on whether the mail is sent by the user or received by the user, it renders the mail card using the `render.mailCard()` function. If `markUnread` is `true`, it increments the corresponding unread mail count. + - If there are replies (`prev` property), it removes the previous mail card from the rendering to avoid duplicates. + +3. **Notification Badges:** + - It updates notification badges on the mail type selector based on the number of unread mails. If the current mail type selector is 'inbox', it adds the unread count to the 'sent' category badge, and vice versa. + +4. **Rendering into UI:** + - It prepends the rendered inbox mails into the `inbox_mail_container` and sent mails into the `sent_mail_container` in the UI. + +## `getChatCard(floID)` + +This function retrieves the chat card element based on the given FloID (or Bitcoin address) from the chats list. + +#### Parameters + +- `floID` (string): The FloID or Bitcoin address for which the chat card needs to be retrieved. + +#### Returns + +- Returns the chat card element associated with the provided FloID or Bitcoin address.

It allows developers to write templates directly in JavaScript without needing a separate build step. uhtml focuses on minimalism and performance, aiming to provide a lightweight solution for rendering dynamic content in web applications. + +## Here's a brief overview of what uhtml does: + +- Template Rendering: uhtml provides a way to create HTML templates directly in JavaScript code. These templates can include dynamic content and data-binding expressions. + +- Virtual DOM: uhtml utilizes a virtual DOM approach, where changes to the UI are first made in memory (virtual DOM), and then efficiently applied to the actual DOM, reducing unnecessary reflows and repaints. + +- Efficiency: uhtml is designed to be incredibly fast and efficient. It achieves this by minimizing the overhead associated with creating and updating DOM elements. + +- Reactivity: uhtml templates can be reactive, meaning they can automatically update when the underlying data changes. This reactivity is often used in modern web frameworks to create responsive and dynamic user interfaces. + +## Explain the UI process + +### `getRef(elementId)` +getRef is the cornerstone of UI in Messenger App. getRef(elementId), is a custom utility function designed to improve the efficiency of accessing DOM elements by their IDs. It provides a way to cache references to DOM elements and reuse them, reducing the number of times the actual DOM is queried. Instead of using `document.getElementById(elementId)` directly in the code, we use `getRef(elementId)` to access the DOM elements. The function takes care of efficient element retrieval and caching. + +getRef(elementId) Function: + +1. getRef(elementId) is a custom JavaScript function used to obtain references to DOM elements using their unique IDs. It optimizes the process of accessing DOM elements by caching the references, allowing for efficient reuse without the need to repeatedly query the DOM. When you call getRef('mail_contact_list'), it returns the DOM element with the ID 'mail_contact_list'. + +2. We use getRef(elementId) instead of document.getElementById + +### uhtml Library Usage: + +1. uhtml is a JavaScript library for efficient and lightweight HTML templating and rendering. It allows you to create HTML templates directly in your JavaScript code. + +2. The line const { html, render: renderElem } = uhtml; imports the html function and an alias for the render function from the uhtml library. The html function is used to create HTML template literals, and renderElem is used to render those templates into DOM elements efficiently. + +- Rendering HTML with renderElem(): + +1. The code renderElem(getRef('mail_contact_list'), html${mailingContacts}) combines the previously mentioned concepts. Here's what's happening: + +2. html${mailingContacts} creates an HTML template literal using the uhtml library. It represents the HTML structure defined by the mailingContacts variable. + +3. getRef('mail_contact_list') retrieves the DOM element with the ID 'mail_contact_list' using the custom getRef() function. + +4. renderElem(targetElement, htmlTemplate) is a call to the renderElem function from the uhtml library. It takes two parameters: the target DOM element where the rendered HTML will be appended (getRef('mail_contact_list') in this case) and the HTML template created with the html function. + +### A direct simple example explaining the render logic + +``` + + + + + + + Dynamic List with uhtml + + + +
+ + + + + + +``` + +### Functions created for Rendering + + +``` + messenger.renderUI.chats = renderChatList; + messenger.renderUI.directChat = renderDirectUI; + messenger.renderUI.groupChat = renderGroupUI; + messenger.renderUI.pipeline = renderPipelineUI; + messenger.renderUI.mails = m => renderMailList(m, false); + messenger.renderUI.marked = renderMarked; +``` + +### There are two meanings of render in the UI of messenger application + +1. In class lazyloader, this.render() is a method internal to lazyloader based objects +2. In uhtml invocations, render creates actual html when `html` parameter is fed to it +3. Sometimes in apps like BTCWallet, render is an object with collection of functions like addressDetails, and txDetails. However, its not used in messenger. + +### Example of uhtml html creation + +- METHOD 1: render.something () In the code below function takes floID as input parameter, and return uhtml compatible html. This can then be fed to `render.selectableContact(contact)` for actual HTML creation + + +``` +//HTML creation stage +selectableContact(floID) { + const name = getContactName(floID) + const initial = name.charAt(0) + return html` + + ` + } + +//At render stage +render.selectableContact(contact); +``` + +- METHOD 2: renderElem(getRef,html) method. Another way we have used to to achieve html from render is the code snippet below using renderElem function + +``` + const { html, render: renderElem } = uhtml; + + function renderContactList(contactList = floGlobals.contacts) { + const contacts = Object.keys(contactList) + .sort((a, b) => getContactName(a).localeCompare(getContactName(b))) + .map(floID => { + const isSelected = selectedMembers.has(floID) + return render.contactCard(floID, { type: 'contact', isSelected, ref: getRef('contacts_container') }) + }) + renderElem(getRef('contacts_container'), html`${contacts}`) + } +``` +## How do you create new models + +- Lets look at usage of createPipeline function which uses `TYPE_BTC_MULTISIG` model here. + +``` + createPipeline(TYPE_BTC_MULTISIG, co_owners, 32, decode.pubkeys).then(pipeline => { + let message = encrypt(tx_hex, pipeline.eKey); + sendRaw(message, pipeline.id, "TRANSACTION", false) + .then(result => resolve(pipeline.id)) + .catch(error => reject(error)) //SENDRAW + }).catch(error => reject(error)) //CREATE PIPELINE +``` + +- To design a new model, you need to define the states the pipeline in the model will take, and also define the message types that will move the state forward. +- A model tells what are the types of messages in that system, and how should they be handled. There is no explicit definition of model. Rather we straight define the processing logic as part of processData.pipeLine function, and it initiates the model. +- You need to define what are the type of messages in your model. For instance the message types for `TYPE_BTC_MULTISIG` model are "TRANSACTION", "BROADCAST" and "MESSAGE". +- If the model message type is "TRANSACTION", then it needs to be signed by anyone of the person who sees this first, and then needs to sign the BTC Multisig transaction. +- If the model message type is "BROADCAST", then all signatures are received, and multisig messaeg has to be broadcasted to the blockchain. +- If the model message type is "MESSAGE", then simply show the message to all members in the pipeline +- Similarly as part of model design, you need to identify the types of messages for the models first. +- Then you need to create the processing logic for each type of message in processData.pipeline[MODEL_NAME]. It will have a common processing section and switch case for each of the message type +- A pipelines moves its state forward as the message type changes due to action of members. +- The model processing logic specified how the state of pipeline changes. +- In this example the state of pipeline changes as soon as one member performs an action which leads him client to proclaim the state of pipeline has moved to the next message +- States in TYPE_BTC_MULTISIG model are Create -> Transact -> Transact -> Broadcast -> close if it is 2 of 3 BTC Multisig +- After the processing, the message has to be given to inboxes of correct recipients like using `newInbox.messages[vc] = data;` +- You should also store a copy of that message locally like using `compactIDB.addData("messages", Object.assign({}, data),${pipeID}|${vc});` +- Every pipeline is identified by a system generated pipeID which is made available to creator and members when a new pipleline is created + +``` +//pipeline model for btc multisig + processData.pipeline[TYPE_BTC_MULTISIG] = function (pipeID) { + return (unparsed, newInbox) => { + if (!_loaded.pipeline[pipeID].members.includes(floCrypto.toFloID(unparsed.senderID))) + return; + let data = { + time: unparsed.time, + sender: unparsed.senderID, + pipeID: unparsed.receiverID + } + let vc = unparsed.vectorClock, + k = _loaded.pipeline[pipeID].eKey; + unparsed.message = decrypt(unparsed.message, k) + //store the pubKey if not stored already + floDapps.storePubKey(unparsed.senderID, unparsed.pubKey); + data.type = unparsed.type; + switch (unparsed.type) { + case "TRANSACTION": { + data.tx_hex = unparsed.message; + break; + } + case "BROADCAST": { + data.txid = unparsed.message; + //the following check is done on parallel (in background) instead of sync + btcOperator.getTx.hex(data.txid).then(tx_hex_final => { + getChat(pipeID).then(result => { + let tx_hex_inital = Object.keys(result).sort().map(i => result[i].tx_hex).filter(x => x).shift(); + if (btcOperator.checkIfSameTx(tx_hex_inital, tx_hex_final)) + disablePipeline(pipeID); + }).catch(error => console.error(error)) + }).catch(error => console.error(error)) + break; + } + case "MESSAGE": { + data.message = encrypt(unparsed.message); + break; + } + } + compactIDB.addData("messages", Object.assign({}, data), `${pipeID}|${vc}`); + if (data.message) + data.message = decrypt(data.message); + newInbox.messages[vc] = data; + } + } +``` + +## Ok. The model is created. How do I use it + +- After a model has been created in processData.pipeline[YOUR_MODEL_NAME] with pipeID as the input parameter, the first action is creation of pipeline using that model. +- Pipeline creation is a standard function, and as new model creator, the system does it all for you. All you have to do is to use messenger.createPipeline with model parameter as YOUR_MODEL_NAME. +- Pipeline creation does not need a special message type. It will be created by the initiator, and sent as messages to everyone who is member of that pipeline. +- However once the message has been given to all users, a valid action from any of them can move the state of pipeline forward, and your model processing logic has to handle what do do next. +- Such sequence of actions has to be defined till the state reaches closure. +- You can also define role based messages in model processing logic, and assign those roles to specific Bitcoin or FLO IDs. Each of them will need their own message type. Switch case of message type has has handle the sequencing of hange of state. +- Role based implementation was not needed in Multisig cases. But it could be created if use case emerges by expanding the processing states. +- In theory role definition can be done at model stage.
