Parcel: newly generated css is not injected into html

[gnijuohz]

Choose one: is this a 🐛 bug report or 🙋 feature request?
I think it's a bug

1) If a HTML file links to index.js and index.js import index.css, parcel will insert a link tag in the generated HTML. Everything works fine. 👍

2) However, if index.js initially doesn't import index.css and instead the css file is created and imported in index.js after running Parcel, a css bundle is correctly generated but not inserted in the generated HTML files. 😢

🎛 Configuration (.babelrc, package.json, cli command)

no babel configuration.

🤔 Expected Behavior

a new link tag is inserted into the generated HTML and points to the newly generated CSS bundle

😯 Current Behavior

The generated HTML file does not link to the generated CSS bundle

💁 Possible Solution

Not sure. Maybe detecting cases like this and re-generating the HTML accordingly? I see some relevant logic in HTMLPackage.js but it's not rerun in this case.

🔦 Context

I sometimes start a project without CSS and only create them and import them after I started running Parcel. Currently I have to restart Parcel after doing that to make it work.

Just got the same problem.
Oh change parcel build index.js to parcel build index.html works.

Yup, I have the same issue. Wasted about 20 minutes trying to figure out what I was doing wrong until I realized I needed to restart.
