build/js/ngl.dev.js

[forever-happy-h]

Here I want to ask a stupid question: I downloaded NGL but did not find the build/js/ngl.dev.js file, how do I get it？

Thank you

The git repository contains the sources. You can either

Build from source using node:

• you'll need some kind of vaguely posix-y terminal: (most linux and mac would just work, or WSL/git-bash on Windows)
• Have node installed

git clone https://github.com/nglviewer/ngl.git
cd ngl
npm install
npm run build

You can grab the built version from npm (it won't have the ngl.dev.js file, but it'll have a couple of different minified formats). You can get directy from npm: https://registry.npmjs.org/ngl/-/ngl-2.3.1.tgz

Or the unpkg site is quite useful for browsing / picking individual files: https://unpkg.com/browse/ngl@2.3.1/dist/

Note, there's both ngl.js and ngl.js.map files, ngl.js is minified production code, but if you put them in the same directory on your webserver then when you open dev tools in your browser you should see and be able to step through NGL source code.
