Steps to reproduce
build CommonJS lib using --target lib --formats commonjs
npm run build:lib
node test_dist.js
the output of webpack4
module.exports = //...
the output of webpack5
module.exports["my-libname"] = //...
What is expected?
Consistent behavior
What is actually happening?
The behavior of output.library
is different from webpack@4
when setting output.libraryTarget: 'commonjs2'
maybe we should omit the output.library
when libraryTarget: 'commonjs2'
to make the behavior consistent
