Babel Plugin

Relay requires a Babel plugin to convert GraphQL to compiler-generated runtime artifacts. Depending upon what framework/bundler you are using, there may be a framwork-specific plugin you can use:

• Vite: vite-pugin-relay
• Next.js: Relay config opton
• SWC: @swc/plugin-relay

If not, you can install the Babel plugin manually:

yarn add --dev babel-plugin-relay graphql

Add "relay" to the list of plugins in your .babelrc file:

{
  "plugins": ["relay"]
}

Please note that the "relay" plugin should run before other plugins or presets to ensure the graphql template literals are correctly transformed. See Babel's documentation on this topic.
