Is t

Answer 1

GitHub is maintaining a namespace for each PR in the original repo, so this works as well:

npm install <user>/<repo>#pull/<id>/head

NOTE: It doesn't seeem to be working with NPM v. 5. See the comment below.

for example:

npm i --save-dev json-schema-faker/json-schema-faker#pull/129/head

or with yarn:

yarn add <user>/<repo>#<id>/head

for example:

yarn add json-schema-faker/json-schema-faker#129/head

Note that in Yarn case there is no pull/ segment in the package identifier.

This may be helpful if you need to automate the installation or repo / branch from where PR is originating is removed. See also Modifying an inactive pull request locally at GitHub.

"How to install NodeJS package from GitHub directly?" mentions that you can specify a branch.

So if you know the repo and branch from which a PR comes from, you can do a:

npm install git+https://github.com/user/repo.git#branch 

Worth saying that you might need to escape the # to use a specific branch from the shell, i.e.:

npm install git+https://github.com/user/repo.git\#branch 

Note that repository you want to install must be a npm module, it must contain a package.json file or else you will get this error:

Error: ENOENT, open 'tmp.tgz-unpack/package.json'.
