  + Note that the `GraphQLApi` construct used to create both `GET` and `POST` routes. In most cases, only `POST` is used. You can also create the `GET` route like this:
  +
  + ```diff
  + new Api(stack, "api", {
  + routes: {
  + + "GET /": {
  + + type: "graphql",
  + + function: "src/graphql.handler",
  + + },
  + "POST /": {
  + type: "graphql",
  + function: "src/graphql.handler",
  + }
  + }
  + });
  + ```
  +
  3. ViteStaticSite: The `ViteStaticSite` construct is deprecated, and will be removed in SST v2. **Use the `StaticSite` construct instead. Specify `buildCommand`, `buildOutput`, and rename `typesPath` to `vite.types`**.
