@hendotcat/11tysnap NPM

11tysnap is a server-side React plugin for Eleventy. It lets you hook up React to do server-side rendering in your Eleventy site without any painful Webpack or Babel configuration work. Just add the plugin, set up the runtime JSX/TSX loader of your choice, and start writing Eleventy templates in React right away.

This plugin deliberately doesn't include any client-side React bundling. If you really need client-side React then Eleventy might not be the best option for you. If you really really really need client-side React and Eleventy then unfortunately this probably isn't the plugin for you.

Installation

yarn add -D @hendotcat/11tysnap react react-dom

Usage

This example uses esbuild-register. If you're trying to set up a React-based Eleventy site for the first time and aren't sure of yourself yet, esbuild-register is your best option: it'll work with both JSX and TSX without requiring any config of its own apart from the register() call below.

const { reactPlugin } = require("@hendotcat/11tysnap")
const { register } = require("esbuild-register/dist/node")

register()

module.exports = function(eleventyConfig) {
  eleventyConfig.addPlugin(reactPlugin)
}

If you know what you're doing and you want to use another loader such as @babel/node, @babel/runner, @esbuild/runner, or ts-node, those all work just fine with 11tysnap too. Check out the examples directory to see usage examples of all of those and more.

Options

`verbose`

Pass verbose: true to the plugin and it'll output a whole bunch of information about what it's doing. This is mostly useful for debugging. Please enable this this option if you're reporting a bug in 11tysnap.

Error Codes

11tysnap will try to help you set it up properly. If you make a mistake, it'll try to help you understand. For some mistakes that it can recognize, it'll print a link in the build output pointing at one of these error codes to help you troubleshoot.
