Install Farfetched ​

Basic setup ​

First, you need to install Farfetched and its peer dependency:

pnpm install @farfetched/core effector

yarn add @farfetched/core effector

npm install @farfetched/core effector

Actually, that is all what you need to start, but consider installing one of the following integrations to improve your DX with popular tools:

• effector-solid and @farfetched/solid with delicious helpers for Solid
• effector-react with nice hooks for React

Additional tools ​

For some advanced usage, like writing tests and server-side rendering, Farfetched requires a few code transformations. You can write it by hands, but it is a boring job that you can forward to a machine. Effector's ecosystem provides a few tools to help you with that.

Babel plugin

If your project already uses Babel, you do not have to install any additional packages, just modify your Babel config with the following plugin:

{
  "plugins": ["effector/babel-plugin"]
}

SWC plugin

SWC is a blazing fast alternative to Babel. If you are using it, you can install @effector/swc-plugin to get the same DX as with Babel.

pnpm install --dev @effector/swc-plugin @swc/core

yarn add --dev @effector/swc-plugin @swc/core

npm install --dev @effector/swc-plugin @swc/core

Now just modify your .swcrc config to enable installed plugin:

{
  "$schema": "https://json.schemastore.org/swcrc",
  "jsc": {
    "experimental": {
      "plugins": ["@effector/swc-plugin"]
    }
  }
}

Vite

If you are using Vite, please read the recipe about it.
