 By default, TypeScript (LSP) will complain about importing files with the `.gleam` extension. There are two choices for fixes:

 - Alternatively, if the vite dev server is running you can have full type safety when importing from Gleam. `npm i ts-gleam`. Create a `tsconfig.json`/`jsconfig.json` and set `compilerOptions.plugins` to `[{"name": "ts-gleam"}]` (**RECOMMENDED**)
