Bit is the AI-powered development workspace with reusable components and zero overhead for the era of AI. Bit organizes source code into composable components, empowering to build reliable, scalable and consistent applications. It supports local AI agents via MCP for creating and composing reusable components at ease.

⚡Features

• Shell applications. Compose reusable components and features into application shells.
• Reusable components. Create reusable UI components and modules to reuse across your software.
• Standard building blocks. Define the blueprints templates for creating components for devs and AI as one.
• Atmoic and safe deployments. Ensure simple, safe and optimized deployments of apps and services for testing and production.

Bit supports all tooling in the JS ecosystem and comes out of the box with official dev environments forNodeJS,React,Angular,Vue,React Native,NextJS andfar more. All are native to TypeScript and ESM and equipped with the best dev tooling.

Bit is a fit to every codebase structure. You can use Bit components in a monorepo, polyrepo, or even without repositories at all.

Use the Bit installer to install Bit to be available on your PATH.

npx @teambit/bvm install

Initialize Bit on a new folder or in an existing project by running the following command:

bit init --default-scope my-org.my-project

Make sure tocreate your scope on the Bit platform and use the right org and project name. After running the command, Bit is initialized on the chosen directory, and ready to be used via Bit commands,AI agent, your editor or the Bit UI!

Create the application shell to run, compose and deploy your application:

bit create react-app corporate-website

Run the platform:

bit run corporate-website

Head tohttp://localhost:3000 to view your application shell. You can start composing the application layout and specific pages to build your application. Learn more onbuilding shell applications.

Create the components to compose into the feature. Run the following command to create a new React UI component for the application login route:

bit create react pages/login

Find simple guides for creating NodeJS modules, UI components and apps, backend services and more on theCreate Component docs.

Compose the component into the application shell:

import{Login}from'@my-org/users.pages.login';import{Routes,Route}from'react-router-dom';exportfunctionCorporateWebsite(){return(<AcmeTheme><NavigationProvider><Routes><Routepath="/"element={<div>Helloworld</div>}/><Routepath="/login"element={<Login/>}/></Routes></NavigationProvider></AcmeTheme>);}

Head tohttp://localhost:3000/login to view your new login page.You can use bit templates to list official templates or find guides for creating React hooks, backend services, NodeJS modules, UI components and more on ourcreate components docs. Optionally, use bit start to run the Bit UI to preview components in isolation.

You can either use hosted scopes onBit Cloud or byhosting scopes on your own. Use the following command to create your Bit Cloud account and your first scope.

bit login

Use semantic versioning to version your components:

bit tag --message"my first release" --major

By default, Bit usesRipple CI to build components. You can use the--build flag to build the components on the local machine. To tag and export from your CI of choice to automate the release process or useour official CI scripts.

After versioning, you can proceed to release your components:

bitexport

Head over to yourbit.cloud account to see your components build progress. Once the build process is completed, the components will be available for use using standard package managers:

npm install @my-org/users.pages.login

• Create more components
• Setup your editor
• Configure CI of choice
• Start from an existing project

Bit is entirely built with Bit and you can find all its components onBit Cloud.
