​
Installing the CLI

Prerequisite: Please install Node.js before proceeding.
1

Install the CLI.

Run the following command to install the CLI:
npm i -g mint
2

Preview locally.

Navigate to your docs directory (where your docs.json file is located) and execute the following command:
mint dev
A local preview of your documentation will be available at http://localhost:3000.
Alternatively, if you do not want to install the CLI globally, you can run a one-time script: 
npx mint dev

​
Updates

If your local preview is out of sync with what you see on the web in the production version, update your local CLI: 
mint update
If this mint update command is not available on your local version, re-install the CLI with the latest version: 
npm i -g mint@latest

​
Custom ports

By default, the CLI uses port 3000. You can customize the port using the --port flag. To run the CLI on port 3333, for instance, use this command: 
mint dev --port 3333
If you attempt to run on a port that is already in use, it will use the next available port: 
Port 3000 is already in use. Trying 3001 instead.

​
Additional commands

While mint dev is the most commonly used command, there are other commands you can use to manage your documentation. The CLI can assist with validating reference links made in your documentation. To identify any broken links, use the following command: 
mint broken-links

​
Checking OpenAPI spec

You can use the CLI to check your OpenAPI file for errors using the following command: 
mint openapi-check <openapiFilenameOrUrl>
You can pass in a filename (e.g. ./openapi.yaml) or a URL (e.g. https://petstore3.swagger.io/api/v3/openapi.json).

​
Renaming files

You can rename and update all references to files using the following command: 
mint rename <oldFilename> <newFilename>

​
Formatting

While developing locally, we recommend using extensions in your IDE to recognize and format MDX files. If you use Cursor, Windsurf, or VSCode, we recommend the MDX VSCode extension for syntax highlighting, and Prettier for code formatting. If you use JetBrains, we recommend the MDX IntelliJ IDEA plugin for syntax highlighting, and setting up Prettier for code formatting.
