Here's my suggestion if you want faster builds: In development, use an index.html that loads it directly from the filesystem, using a single-pass annotation remover such as https://github.com/alangpierce/sucrase https://github.com/alangpierce/sucrase A single-pass transpiler doesn't build an AST, instead just looping over everything once, which will surely make it faster than esbuild. In production, use a bundler like snowpack.
