rustwasm/wasm-pack v0.4.0

🌟 0.4.0

on GitHub

This release has a ton of awesome things in it, but the best thing is that
almost all of this awesome work is brought to you by a new contributor
to wasm-pack. Welcome ya'll! We're so glad to have you!

✨ Features

• 🎏 New Flags

  • --mode flag for skipping steps when calling init - ashleygwilliams, pull/186

    After teaching and working with wasm-pack for some time, it's clear that people would
    like the flexibility to run some of the steps included in the init command and not others.
    This release introduces a --mode flag that you can pass to init. The two modes currently
    available are skip-build and no-installs and they are explained below. In the future,
    we are looking to change the init interface, and potentially to split it into two commands.
    If you have thoughts or opinions on this, please weigh in on issue/188!

    • skip-build mode - kohensu, pull/151

      wasm-pack init --mode skip-build
      

      Sometimes you want to run some of the shorter meta-data steps that
      wasm-pack init does for you without all the longer build steps. Now
      you can! Additionally, this PR was a fantastic refactor that allows even
      more custom build configurations will be simple to implement!

    • no-installs mode - ashleygwilliams, pull/186

      wasm-pack init --mode no-installs
      

      Sometimes you want to run wasm-pack and not have it modify your global
      env by installing stuff! Or maybe you are just in a hurry and trust your
      env is set up correctly- now the --mode no-install option allows you to
      do this.

  • --debug - clanehin, pull/127

    wasm-pack init --debug
    

    Find yourself needing to compile your Rust in development mode? You can now
    pass the --debug flag to do so! Thanks so much to clanehin for filing
    issue/126 for this feature... and then implementing it!

• ✅ New Checks

  • ensure you have cdylib crate type - kendromelon, pull/150

    One of the biggest mistakes we've seen beginners make is forgetting to declare
    the cdylib crate type in their Cargo.toml before running wasm-pack init.
    This PR fixes that, and comes from someone who ran into this exact issue learning
    about wasm-pack at JSConfEU! Love when it works out like this.

  • ensure you have declared wasm-bindgen as a dep - robertohuertasm, pull/162

    Another easy mistake to make is to forget to declare wasm-bindgen as a
    dependency in your Cargo.toml. Now wasm-pack will check and make sure you
    have it set before doing a bunch of long build steps :)

  • ensure you are running nightly - FreeMasen, pull/172

    wasm-pack currently requires that you run it with nightly Rust. Now, wasm-pack
    will make sure you have nightly installed and will ensure that cargo build is run
    with nightly. Thanks so much to FreeMasen for filing issue/171 and fixing it!

🤕 Fixes

• fixed broken progress bar spinner - migerh, pull/164

  Oh no! We broke the progress bar spinner in version 0.3.0. Thankfully, it's
  fixed now- with a thoughtful refactor that also makes the underlying code
  sounder overall.

🛠️ Maintenance

• WIP bot - ashleygwilliams & mgattozzi, issue/170

  We've got a lot of work happening on wasm-pack so it's good to have a bit
  of protection from accidentally merging a Work In Progress. As a result, we
  now have the WIP Github App set up on wasm-pack. Great suggestion mgattozzi!

• modularize command.rs - ashleygwilliams, pull/182

  Thanks to the growth of wasm-pack, command.rs was getting pretty long.
  We've broken it out into per command modules now, to help make it easier to
  read and maintain!

• improve PoisonError conversion - migerh, pull/187

  As part of the awesome progress bar spinner fix in pull/164, migerh introduced
  a small concern with an unwrap due to an outstanding need to convert PoisonError
  into wasm-pack's custom Error. Though not a critical concern, migerh mitigated
  this right away by replacing std::sync::RwLock with the parking_lot crate!
  This cleaned up the code even more than the previous patch!

• wasm category for crates.io discovery- TomasHubelbauer, pull/149

  crates.io has categories to help folks discover crates, be we weren't
  leveraging it! Now- if you explore the wasm category on crates.io
  you'll see wasm-pack!

• human panic is now 1.0.0 - spacekookie, pull/156

  Congrats friends! We like what you do.

📖 Documentation

• cleaned up the README - ashleygwilliams, pull/155

  Our README was struggling with a common problem- doing too much at once.
  More specifically, it wasn't clear who the audience was, contributers or
  end users? We've cleaned up our README and created a document specifically
  to help contributors get up and running.
