🚀 CodeGear - Online Code Editor

Documentation

Take a look at the documentation to see a detailed overview of the project.

Why it is awesome?

CodeGear is an online code editor (like VS Code) in which youcould conduct online interviews and edit code in real time with other people.

Customization

It supports 10-15 themes (including popular ones like Monokai or Nord)

Moreover, you can create your own unique theme. You can customize the color, background, font size, tab size (default is 4 spaces) and much more!

Functionality

You can find, replace text, create tabs, and also run your code (javascript and python are currently supported).

Note All your changes are saved to localStorage automatically, so you don't have to save your code manually.

Real-time Changes

You can also log in and send a link to another person so that he can come in and edit the code with you in real time.

What is the essence of this project?

In fact, the project was seen as an opportunity to try out a large number of different technologies. And I succeeded - I created an environment in which you can experiment and introduce new technologies and functionality.

Technology Stack

🌟 Frontend

• Preact
• MobX
• Styled-components
• react-spring
• FSD + Microfrontends

💻 Backend

• NestJS
• Kafka
• Docker
• Microservices + CQRS
• Prisma

And, of course, Nx, with its configurations and a lot of binding scripts.

Why are there so many configurations?

Firstly, I am an enjoyer of complex solutions and large projects. Secondly, this was the goal of the project - to create something unusual, large and unlike ordinary pet projects.

This project is more about how it is made than what it can do. Check out the documentation to learn more about the project.

Something like that! 🚀 💫

Installation

Prerequisites

• Node.js version 20 or higher.
• Docker version 21 or higher.
• Yarn version 3.2.0 or higher.

Setting environment variables

Copy the environment variables from env folder. This file contains all the configuration needed to run the project.

$ cp tools/dev/src/env/* .
$ mv .override.env .docker

1. Manual Installation

Install dependencies.

$ yarn install

Run services like redis, kafka, zookeeper and others in docker in a virtual environment.

$ nx run:dev docker

Start the project. This simple command will launch a cluster of microservices and all frontend applications! It will also collect all dependent libraries that are located in the packages folder.

$ nx serve

2. Run in docker virtual environment (development mode)

You can run the project in one large container, with docker volumes set to apps and packages to enable hot-reload.

$ yarn dlx nx run:dev:full docker

Since this is a monorepository, running each microservice in a separate container is not beneficial in terms of memory (2.5GB per container) in development mode.

The full flag means that in addition to the main services like mysql, you also run runtime services, that is, microservices and applications.

3. Run in docker virtual environment (production mode)

$ yarn dlx nx run:prod docker

Unlike development mode, each application or microservice will be launched in isolation from others (using multistage build) and thus it will not take up much memory on your disk (40MB-200MB each container).

The dev server should be running at http://localhost:3000. Visit the URL in your browser to see project in action.

Nx-Console It is highly recommended to add the Nx-Console plugin to your IDE, as it greatly simplifies the management of > various scripts and is indispensable in my opinion in a monorepository.
