Parcel: Multiple extension support

[tomerigal]

🙋 feature request

Multiple extension support (e.g tar.gz)

🤔 Expected Behavior

Resolve asset with full extension

😯 Current Behavior

Resolve asset with part of extension (e.g .gz)

💁 Possible Solution

Split extension from the first dot.

🔦 Context

Create plugin with multiple dots extensions, or just load tar.gz file.

💻 Examples

import download from './compress.tar.gz';

I found a regex which might be helping: https://regex101.com/r/nQ4oW8/1
/(?:\.ext[1-4])+$/i

found here: https://stackoverflow.com/a/21607977/3793309

This requires a set of predefined extensions, but it's the most straightforward approach I could think of right now.

I wouldn't split after first dot, since this could bring new issues, e.g. a plugin which has files like myPlugin.v1.1.js or like your example: import download from './compress.tar.gz'; <= .tar.gz

The actual extracting of the extension will be fairly hard as a filename is allowed to contain dots that are not part of any extension, I propose the following:

Regex out extensions
=> Search known extensions
  => Match? => Use specified Asset
  => No Match? => Use last extension
        => Match? => Use specified Asset
        => No Match? => Fallback to RawAsset

Going to close this since it is solved in Parcel 2 where plugins are matched using globs. You could use something like *.tar.gz
