# NetlifyDeployer The `NetlifyDeployer` class handles packaging, configuration, and deployment by adapting Mastra's output to create an optimized version of your server. It extends the base [`Deployer`](https://mastra.ai/reference/deployer) class with Netlify specific functionality. It enables you to run Mastra within Netlify functions. ## Installation In order to use `NetlifyDeployer`, you need to install the `@mastra/deployer-netlify` package: **npm**: ```bash npm install @mastra/deployer-netlify@latest ``` **pnpm**: ```bash pnpm add @mastra/deployer-netlify@latest ``` **Yarn**: ```bash yarn add @mastra/deployer-netlify@latest ``` **Bun**: ```bash bun add @mastra/deployer-netlify@latest ``` ## Usage example Import `NetlifyDeployer` and set it as the deployer in your Mastra configuration: ```typescript import { Mastra } from "@mastra/core"; import { NetlifyDeployer } from "@mastra/deployer-netlify"; export const mastra = new Mastra({ deployer: new NetlifyDeployer(), }); ``` ## Output After running `mastra build`, the deployer generates a `.netlify` folder. The build output includes all agents, tools, and workflows of your project, alongside a special `config.json` file. The `config.json` file configures the behavior of Netlify functions. ```bash your-project/ └── .netlify/ └── v1/ ├── config.json └── functions/ └── api/ ├── index.mjs ├── package.json └── node_modules/ ``` The `config.json` file contains: ```json { "functions": { "directory": ".netlify/v1/functions", "node_bundler": "none", "included_files": [ ".netlify/v1/functions/**" ] }, "redirects": [ { "force": true, "from": "/*", "to": "/.netlify/functions/api/:splat", "status": 200 } ] } ```
