parcel: Only first change is tracked when index.html is not in the root dir

🐛 bug report

When running parcel and then changing source files a few times, the page is reloaded after the first edit only and no more reloads happen.

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

parcel src/index.html

{
  "name": "parcel-example1",
  "version": "1.0.0",
  "description": "example",
  "scripts": {
    "start": "parcel src/index.html"
  }
}

🤔 Expected Behavior

Page reloads after each change.

😯 Current Behavior

Page reloads after first change only.

💁 Possible Solution

💻 Code Sample

src
  - index.html
  - main.js
package.json

<html>
  <head>
    <title>Parcel Example</title>
    <meta charset="UTF-8"/>
  </head>
  <body>
    <div id="calendar">Hello world!</div>
    <script src="main.js"></script>
  </body>
</html>

FYI, we’ve decided to build our own watcher for Parcel 2, and it should be much more reliable with safe write and other issues we’ve seen with chokidar. https://github.com/parcel-bundler/watcher

Fadora 28 parcel 1.10.3 - same problem reload works only first time for each file.

Here a repo: https://github.com/ManzDev/css-grid-cards

git clone and parcel serve src/index.pug and fail on checkout branches. Test on Windows 10 Pro N and Windows 10.

Fails on Parcel 1.9.6 Fails on Parcel 1.9.7 Down to Parcel 1.9.2 and works.

Ive looked a bit at other file system watchers and I think https://github.com/Axosoft/nsfw seems to be a good match to what parcel needs. Its used by VS Code among others, so it should be battle tested.

Edit: would a pull request for using nsfw be welcomed?

Im having a similar issue, where parcel is running inside a docker container (debian based, node v9, entrypoint = src/index.html) and only the first change to a file is registered by parcel. Any subsequent changes to a file can be seen in the docker container but the parcel file watcher seems to not care.

How come parcel needs its own home rolled file watcher? Please consider using a more battle tested solution.

We are stuck using parcel 1.9.2 at the moment.
