parcel@next isn't bundling at all (without further config)

See original GitHub issue

🐛 bug report

parcel is supposed to be zero-config, but parcel@2 seems to default to “bundling for node”, which isn’t Parcel’s most common purpose (I would guess)

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

This is the full repro:

npm i webext-options-sync parcel@next --no-save
echo "import 'webext-options-sync'" > source.js
npx parcel build source.js

Old repro

npm init -y
npm i webext-options-sync parcel@next
echo "import 'webext-options-sync'" > source.js
npx parcel build source.js

🤔 Expected Behavior

✨  Built in 1.93s.

dist/source.js.map    61.69 KB     21ms
dist/source.js        18.06 KB    1.62s

The module webext-options-sync is bundled just like parcel@1 does.

😯 Current Behavior

✨ Built in 2.06s.
 
index.js         31 B     95ms
└── source.js    75 B    964ms

It generates index.js with this content:

require("webext-options-sync");

💁 Possible Solution

Default to regular bundling for browsers, rather than generating a CommonJS file.

Ah, but that doesn’t happen for me?
