You should be able to access it from node_modules/.bin/ng

If you already have the workspace created.

You can invoke it like such

 npm run ng <command> 

there are also predefined scripts in your package.json like npm start and npm test etc...

Alternatively you could also use npx https://www.npmjs.com/package/npx

Closing this as its been answered.

@hansl Is there documentation anywhere for this? If not, I would like to keep this issue open. I can open a separate issue, but I think it would be better to keep it here.

Hi @alan-agius4 , why npm run ng <command> works when not globally cli installed? Does npm can figure out the ng means node_modules/.bin/ng ?
Look forward to your reply. Thanks.

[alan-agius4]

Yes, this is based on how node resolution work.

As when using a node package inside an npm script it will try locate the module locally first and then it will look for them globally.

[SangKa]

Thanks for your inspiring, I found the reason in the npm document.

In addition to the shell's pre-existing PATH, npm run adds node_modules/.bin to the PATH provided to scripts. Any binaries provided by locally-installed dependencies can be used without the node_modules/.bin prefix. For example, if there is a devDependency on tap in your package, you should write:

"scripts": {"test": "tap test/\*.js"}

instead of

"scripts": {"test": "node_modules/.bin/tap test/\*.js"}  

to run your tests.
