How to specify the path of `package.json` to npm?

Question

I use npm scripts to build my project. I'd like to be able to run the scripts from a different directory. That is, instead of doing the following:

cd project;
npm run build;
cd ..

...I'd like to simply do something like:

npm run build -config project/package.json;

or

npm run build -wd project;

Is this possible?

Answer 1

This worked for me:

npm --prefix /path/to/project run build

Where path/to/project is the directory where your package.json with "build" command defined.
