watch command

[netgusto]

💡 Feature description

It seems that a "watch source" is missing for the build subcommand.

Workaround

First, install fswatch on your system; then, at the root of your project :

fswatch -o -r ./src|xargs -I {} wasm-pack build --debug

i think this sounds great! once i get 0.6.0 out the door we can schedule this for the next release

Here is another solution using cargo-watch:

cargo watch -i .gitignore -i "pkg/*" -s "wasm-pack build"

update! looking to do this soon :) cc @fitzgen rustwasm/rfcs@8aae141

there's a draft implementation of this (and the proposed serve command from rustwasm/rfcs#10 as well) in #745, for what it's worth

[jasonwilliams]

@ashleygwilliams @boringcactus what happened to this? Is there still any work in progress?

I hope this comes through. I used onchange because I didn't want to force fellow developers to install cargo-watch, but having Watch Mode built in would be great.
