WIP ES2015+ to ES5 transpiler + bundler + minifier in Rust.
Because Webpack+Babel+UglifyJS are both awesome and terrible at the same time.
Requirements
- Rust 1.8.0
Usage
To print out the compiled code to stdout:
$ cargo run -- -f input.js
To compile to a file:
$ cargo run -- -f input.js -o output.js
Things that work:
- A basic pipeline for parsing, transofrmation and code generation.
- Can parse and code gen a large chunk of ES2015+ syntax (not all yet, but getting there).
- The transformer can turn arrow functions into regular function expressions,
adding
.bind(this)
when necessary. - Object shorthand as well as computed properties get transmuted to ES5.
Things that are missing:
- Keep track of location of tokens and later on AST constructs in the original source code.
- Meaningful parse error reporting.
- Any sort of bundling.
- A way to configure which transformations to do, and which to skip.
- Interface with external compilers (Sass, Less, Handlebars), maybe use Neon?
- Think of ways to analize function scopes (necessary for variable name scramling).
