Frontend Setup and Development Guide¶

Setting up and running the frontend of the Trustworthy and Ethical Assurance (TEA) Platform is straightforward with Node.js and npm (Node Package Manager). This guide will walk you through installing the necessary tools, running the development server, and executing tests to ensure everything is set up correctly.

Prerequisites¶

Node.js and npm: Ensure you have Node.js and npm installed on your system. Node.js is a runtime environment that allows you to run JavaScript on the server side. npm, included with Node.js, is the world's largest software registry that facilitates package management for JavaScript.

Backend Setup: Before starting with the frontend, make sure the backend server is up and running as the frontend will need to communicate with it.

Setting Up the Frontend¶

Clone the Repository Start by cloning the TEA Platform repository to your local machine, if you haven't already done so.
```
$ git clone https://github.com/alan-turing-institute/AssurancePlatform.git
```
Navigate to the Frontend Directory Change into the frontend directory within the cloned repository.
```
$ cd AssurancePlatform/frontend
```
Install Dependencies

Run the following command to install all required npm packages specified in the package.json file.
```
$ npm install
```
Run the Development Server

Start the development server to launch the TEA Platform in your default web browser.
```
$ npm start
```
This command will automatically open a new browser tab pointing to http://localhost:3000, where you can start interacting with the frontend application.
Run Tests

It's good practice to run the available tests to ensure that the frontend components are functioning as expected.
```
$ npm run test
```

Additional Setup for SVG Export¶

To enable the export of SVG images from the frontend, you need to install the Mermaid CLI globally on your system.

npm install -g @mermaid-js/mermaid-cli

Troubleshooting SSL Errors¶

If you encounter any SSL errors during setup, try updating npm and forcing an audit fix, followed by updating react-scripts to the latest version.

npm update && \
npm audit fix --force && \
npm i react-scripts@latest

Conclusion¶

By following these steps, you'll have the frontend of the TEA Platform running locally on your development machine, ready for further development and testing.
