You can use the generator library to generate whatever you want in your event-driven architecture apps. Find your preferred method below:


Before you install and use the AsyncAPI CLI and the generator library, ensure you meet the prerequisites below, then install the CLI.

  1. Node.js v12.16 and higher
  2. Npm v6.13.7 and higher

To verify the versions of Node and Npm you have, run the following command on your terminal:

npm -v
node -v

If you don't have either Node or Npm installed, use the official node.js installer.

If you have the correct versions installed, proceed to the CLI installation guide below. Otherwise, upgrading the Npm or Node version is lower than the recommended versions specified above.


The AsyncAPI CLI tool allows you to do many different things with the AsyncAPI document. You can generate message-based API boilerplate code, documentation, or anything else you need as long as you specify it in your template or the existing template already supports it. To use the generator via the AsyncAPI CLI, you need to install the AsyncAPI CLI tool.


Install AsyncAPI CLI using NPM

The AsyncAPI CLI is a NodeJS project, so the easiest way to install it is by using the following npm command:

npm install -g @asyncapi/cli

To install a specific version of the generator tool, pass the version during installation:

npm install -g @asyncapi/cli@{version}


You can install in MacOS by using brew: brew install asyncapi.


You can install in Linux by using dpkg, a package manager for debian:

  1. curl -OL
  2. sudo dpkg -i asyncapi.deb

Other operating systems

For further installation instructions for different operating systems, read the AsyncAPI CLI documentation.

Remember: Each community-developed template is dependent on a certain version of the generator for it to work correctly. Before you install the generator CLI, check the template's package.json for the version of the generator CLI your template is compatible with. Read the versioning docs to learn why it's important to use certain generator versions with your templates.

Update AsyncAPI CLI

There are several reasons why you might want to update your generator version:

  • You have the generator tool installed but want to use the latest released features. To upgrade to the latest version, use the command below:
npm install -g @asyncapi/cli
  • If your template isn't compatible with the latest generator version, you can update it to a specific version of the generator. Check the version you need and specify the version you want by using the @ symbol as shown in the command below:
npm install -g @asyncapi/cli@{version}

Sometimes you have to force additional npm installation like this: npm install -g --force @asyncapi/cli

Uninstall AsyncAPI CLI

To uninstall the generator, use the following command:

npm uninstall @asyncapi/cli -g

📝 Note: To use the generator in your CI/CD pipeline to automate whatever you generate for your event-driven architecture apps, install the AsyncAPI CLI in your pipeline. If you are using GitHub Actions, use Github Actions for Generator.

Generator library in Node.js apps

Use the generator library in your Node.js projects by installing it via the following command: npm install @asyncapi/generator.

Don't include the -g flag in the installation command above since you're not installing the generator library globally but in your Node.js project.
