 If you prefer co-locating your GraphQL queries in your Javascript files, you typically use the [graphql-tag](https://github.com/apollographql/graphql-tag) library to write them. That requires to process the query strings into a GraphQL AST, which will add to the startup time of your application, especially if you have many queries.
 
-To avoid this runtime overhead, you can precompile your queries created with `graphql-tag` using [Babel](http://babeljs.io/). Here are two ways you can do this:

 If you prefer to keep your GraphQL code in separate files (`.graphql` or `.gql`) you can use [babel-plugin-import-graphql](https://github.com/detrohutt/babel-plugin-import-graphql). This plugin still uses `graphql-tag` under the hood, but transparently. You simply `import` your operations/fragments as if each were an export from your GraphQL file. This carries the same precompilation benefits as the above approaches.

 And that's it! All the usages of `import gql from 'graphql-tag'` will be removed, and the calls to `gql` will be replaced by the compiled version.
 
+## Using graphql-tag-swc-plugin
+
+This plugin is the same as [babel-plugin-graphql-tag](#using-babel-plugin-graphql-tag) but for [swc](https://swc.rs/), a fast rust based babel alternative.
+
+Install the plugin in your dev dependencies:
+
+```
+# with npm
+npm install --save-dev graphql-tag-swc-plugin
+
+# or with yarn
+yarn add --dev graphql-tag-swc-plugin
+```
+
+Then add the plugin in your `.swcrc` configuration file:
+
+```
+{
+  jsc: {
+    experimental: {
+      plugins: [
+        ["graphql-tag-swc-plugin",

 ## Using graphql-tag.macro
 
 This approach is a bit more explicit, since you change all your usages of `graphql-tag` for `graphql-tag.macro`, which exports a `gql` function that you can use the same way as the original one. This macro requires the [babel-macros](https://github.com/kentcdodds/babel-macros) plugin, which will do the same as the previous approach but only on the calls that come from the macro import, leaving regular calls to the `graphql-tag` library untouched.
