Do not use npm install or npm update because we don't have package.json in Git repo. You should always use the following command:
./makeThis command will generate package.json, do npm update and compile.
Before testing or publishing, also use ./make command.
mocha test-target-cjs/main.mjsBefore publishing write the changelog.
Q: Why in target-cjs the filename is in .mjs.js format?
A: This way we make the form import "./module-name.mjs" compatible for both browser and Node.js. Note that browsers can't guess file extensions, so to make it browser-compatible we must include the .mjs extension. If we're on browser, then target directory is used, and the import string exactly refers to the full filenames in this directory. If we're on Node.js, then target-cjs is used, and the import string refers to the basename of the filenames in this directory. Node.js can guess file extensions, so omitting file extensions is OK. Therefore, the same import string is correct in both scenarios.
