Give credentials to npm login command line

Question

I need to pass the credentials for npm login in a script. Is there a way to give the credentials similar to the git credentials?

git clone https://username:[email protected]

Answer 1

I found an npm package for this:

Install npm-cli-login and in the terminal/scripts use it as below:

npm-cli-login -u testUser -p testPass -e [email protected]

---

I found two other ways to pass the credentials without the need to use an external command, but be aware that these commands might not work in environments such as Jenkins.

Commands:

# First way
echo -e 'USERNAME\nPASSWORD\nEMAIL' | npm login -e EMAIL -r REGISTRY

# Second way
npm login -e EMAIL -r REGISTRY << EOF
USERNAME
PASSWORD
EMAIL
EOF

Answer 2

Take a look at the .npmrc file you can use this file to set npm configuration variables, such as credentials, registry location, etc... This file is located in your HOME directory. Here is an example .npmrc file to use for reference:

~/.npmrc

registry=https://registry.npmjs.com/
_auth="<token>"
email=<email>
always-auth=true

substitute your email and _auth token appropriately for your credentials. Your script will use these global configurations set within your .npmrc file.

Hopefully that helps!
