This documentation will show you how to set up your environment for Assemblyline frontend development.
-## Install development environment prerequisites
+## Libraries
+
+First off, Assemblyline's frontend uses the following libraries. Here are some key notes when using them while developing a feature on the frontend.
+
+### **[React](https://react.dev)**
+
+The Assemblyline frontend was developed using the React library. It was originally chosen for its popularity and has stood the test of time. Where Angular is a framework because some decisions were made for the developer, React is an unopinionated library allowing the developer to make their own decision for their app. The main advantage of using React is it allows developers to create modular and reusable components throughout the app.
+
+**[ReactDOM](https://react.dev/reference/react-dom)**: React comes with the ReactDOM library that implements the concept of Virtual DOM (VDOM). It works by storing a virtual representation of the DOM tree in memory and whenever an event causes changes of state such as a user clicking on a button or entering text in an input field, the VDOM will reconcile the differences and re-render the components and associated child components where the state change occurred .
+
+**[React Developer Tools](https://react.dev/learn/react-developer-tools)**: You can install this tool as a browser extension to be able to view and track the component's state and to optimize the rendering performance of the app.
+
+- **functions over classes**: In Assemblyline, we prefer to use functional components instead of class components as they seem to have been deprecated or are in legacy support.
+- **Hooks**: Similarly, we use hooks in most use cases ever since they became popular.
+- **Components in a single file**: Components that are only used a limited amount of time should be stored in the same file that they are used in to avoid having to search all over the place for them.
+- **Memoize everything**: Performance optimization is a key factor when it comes to developing Assemblyline's frontend where frequent DOM changes occur. As explained before, a component will have to re-render all its content if one of its props, state or state resulting from hooks has changed. As a good rule of thumb, functional components should be wrapped with `React.memo()`, methods within a component should be implemented with `useCallback()` and use `useMemo()` for state-derived variables to avoid unnecessary re-rendering. Note that React 19 will finally remove the need to memoize everything.
+
+### **[React Router](https://reactrouter.com)**
+
+This library handles all of the "client-side routing" and provides all the hooks to track the state of the location, its parameters and the need to navigate to another location.
+
+- **Code-Splitting and Lazy loading**: In order to reduce the initial bundling size, every page of Assemblyline's frontend is lazy loaded meaning that page's code and all underlying components will only be sent to the user's browser when they first navigate to it.
+- **Vite Chunking**: When building for production, Vite is configured to create chunks, or to split the resulting JavaScript code into multiple files in order to reduce their size. In effect, this reduces the initial loading time by only sending the chunk of code needed to display the requested page.
+
+### **[Typescript](https://www.typescriptlang.org)**
+
+This library adds additional syntax for types that builds on JavaScript. Well integrated into VSCode, it provides the type inference needed to catch errors during development.
+
+- **Type everything**: To make full use of this library, it is encouraged to add typing to all parameters in order to be able to catch potential issues during development.
+
+### **[Material UI](https://mui.com/material-ui)**
+
+Most of the React components that are used in Assemblyline come from the Material UI (MUI) library. It provides all the standard UI element one might expect with minimalistic animation making easy and fast to develop on the frontend.
+
+**[Material Icon](https://mui.com/material-ui/material-icons/)**: Most of Assemblyline's icons and symbols are from Material Icon as they are well integrated with its components.
+
+- **Performance over style**: Note that there's a performance trade-off with using the MUI components where you get the functionalities and the styling but lose a lot of performance. In the case of rendering thousands of elements like buttons in a table, it is much faster to use regular HTML and pure CSS since the UI doesn't have to process all the component's parameters. As an example, we rarely use the `` component from MUI as it doesn't offer anything more than a regular `
` doesn't and the rendering time differences is considerable at scale.
+
+### **[Vite](https://vitejs.dev)**
+
+Vite.js is a build tool which aims to streamline the web development process, making it faster and more efficient for developers. The term comes from the French word for "fast" or "quick". The Assemblyline frontend previously used [Create React App](https://create-react-app.dev/), but moved from it to get faster startup time, hot module replacement (HMR) and build time.
+
+### **[Vitest](https://vitest.dev)**
+
+Because the frontend now uses Vite, it uses Vitest as its testing framework. For the time being, testing components on the frontend is done selectively and mostly on pure functions. Otherwise, having both Typescript and ESLint helps to find issues that might occur during development.
+
+### **[ESLint](https://eslint.org)**
+
+ESLint is a static code analysis tool for identifying problematic patterns or code that don't adhere to certain guidelines or standards in order to maintain code quality and consistency within a codebase. For the most part, the Assemblyline's frontend uses standard rulesets written by the React community.
+
+- **Vite integration**: ESLint was not integrated with Vite runtime to preserve its fast response time during development. To view all the warnings and errors on the frontend's code, execute the `yarn eslint .` command.
+
+## Install the development environment prerequisites
### Clone the UI frontend code
- cd ~/git
- git clone https://github.com/CybercentreCanada/assemblyline-ui-frontend.git
+``` bash
+cd ~/git
+git clone https://github.com/CybercentreCanada/assemblyline-ui-frontend.git
+```
-### Install NodeJS (Ubuntu)
+### Install Node.js (Ubuntu)
-Follow these simple commands to install NodeJS
+[Node.js](https://nodejs.org/en) is the JavaScript runtime that will execute the frontend's code. Using the [Node Version Manager](https://nodejs.org/en/download/package-manager) (NVM) makes it easy to install and manage your Node.js environment. Use these following commands install the Node.js version 20.
- curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -
- sudo apt-get install -y nodejs
+``` bash
+# installs nvm (Node Version Manager)
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh |
+
+# download and install Node.js (you may need to restart the terminal)
+nvm install 20
+
+# verifies the right Node.js version is in the environment
+node -v # should print `v20.14.0`
+
+# verifies the right NPM version is in the environment
+npm -v # should print `10.7.0`
+```
+
+Otherwise, you can follow these simple commands to install Node.js
+
+``` bash

+sudo apt-get install -y nodejs
+```
+
+### Install Yarn
+
+[Yarn](https://classic.yarnpkg.com/en/) is a package manager that is faster and more reliable than NPM to manage and install Node.js packages. Type the following command to install Yarn globally.
+
+``` bash
+# install Yarn
+npm install --global yarn
+
+# check that Yarn is installed by running:
+yarn --version
+```
### Install NPM dependencies

-## Launch the dev environment
+## Frontend development only
+
+The default `docker-compose` configuration is setup for users who only want to work on Assemblyline's frontend. It will deploy the required docker containers of `nginx`, `minio`, `redis` and `elasticsearch` used for any development environment, but will also deploy the `ui` and `socketio` instances as docker containers and will create some test data.
### Dependencies
Go to the `docker` directory and run the following command to launch the Assemblyline database and user interface.
- docker-compose up
+``` bash title="~/git/assemblyline-ui-frontend/docker"
+docker-compose up -d

+
+## Full-Stack Web Development
+
+This development environment is for users who want to make changes to every aspect of Assemblyline. For example, you may want to create new API routes for a new frontend's page.
+
+### Docker configuration
+
+Open the `docker-compose` config file located in the `assemblyline-ui-frontend/docker` directory. Comment out the `create_test_data`, `al_ui` and `al_socketio` services as we will make them run as processes instead of docker containers.
+
+You can also uncomment the `kibana` service if you want a dashboard to view the raw data stored in `elasticsearch`.
+
+### Setup the core services
+
+Follow the instruction highlighted on the [setup script](../env/vscode/setup_script.md) page to create the `alv4` directory with all the core services. With VSCode, you only need to start a `[UI] API Server` process and maybe `[UI] Socket Server` if you are working on a component that requires a socket connection like the `/dashboard`. Keep in mind that any changes made to those processes will require you to reset its instances to see its effect.
