npm adduser via bash

Question

I want to automate the npm login process via a bash script.

I tried it with this snippet:

/usr/bin/expect -f - <<EOD
spawn npm adduser
expect "Username:"
send "myUserName\n"
expect "mail: (this IS public)"
send "my@email.com\n"
EOD

But without luck.

Note: I will change the strings with env variables

for automation it may be better to set up the ~/.npmrc like this https://stackoverflow.com/a/57014522/442837 — dres, Jul 12 '19 at 22:17

@Aurélien Thieriot: thanks for the hint.

I have two solutions for my problem:

Solution 1

export NPM_AUTH_TOKEN=myToken
export NPM_EMAIL=myEmail

create/override ~/.npmrc by following shell script:

echo "_auth = $NPM_AUTH_TOKEN" > ~/.npmrc
echo "email = $NPM_EMAIL" >> ~/.npmrc

Solution 2

export NPM_USERNAME=myUsername
export NPM_PASSWORD=myPassword
export NPM_EMAIL=myEmail

I know the order of the questions. So I can do the following:

npm adduser <<!
$NPM_USERNAME
$NPM_PASSWORD
$NPM_EMAIL
!

Note: solution 2 works only when the user isn't added yet
Otherwise the $NPM_PASSWORD is not necessary

For solution 1, I had to remove the `$` when I ran export. – The Unknown Dev Aug 15 '16 at 15:46

For solution 2, remove $ when exporting. – l.cotonea Oct 16 '16 at 21:53

This way works and with a more elegant expect:

/usr/bin/expect <<EOD
spawn npm adduser
expect {
  "Username:" {send "$USERNAME\r"; exp_continue}
  "Password:" {send "$PASSWORD\r"; exp_continue}
  "Email: (this IS public)" {send "$EMAIL\r"; exp_continue}
}
EOD

maybe this can be done within one line? I have no idea how to put this to gitlab-ci.yml – holms Jun 27 '18 at 11:47
@holms, you can create a script with this content and run it via CI. In my case I run it via Dockerfile: `ADD npm-login.sh $APP_HOME/npm-login.sh` `RUN chmod +x $APP_HOME/npm-login.sh` `RUN $APP_HOME/npm-login.sh` – Seralto Jun 27 '18 at 15:26
I'm using gitlab-ci so I've ended up with this: https://stackoverflow.com/questions/51062370/how-can-i-add-multi-line-bash-eod-command-to-gitlab-ci-yml/51079382#51079382 – holms Jun 28 '18 at 09:32

For people working with a private registry (typically for CI purpose), reaching directly the Rest API may be a solution :

curl -XPUT -H "Content-type: application/json" -d '{ "name": "your_username", "password": "your_password" }' 'http://localhost:4873/-/user/org.couchdb.user:your_username'

This is what npm adduser is doing behind the scene.

Didn't have luck with any answers above on OSX.

This did work though:

npm install -g npm-cli-adduser
npm-cli-adduser -u username -p password -e email -r https://repo.com/nexus

export NPM_USER=user
export NPM_PASS=pass
export NPM_EMAIL=valid email syntax
npx npm-login-cmd

I don't know if it is in any way secured so please do some research before.

But the fact is that npm is storing all those informations into a file. If you look at:

cat ~/.npmrc

It could be interesting enough so you could do the login dance only once.

Everyone knows in here that it's stored there, question how to have a single command for generating it. This is required for automation software like ansible and dockerfiles. – holms Jun 27 '18 at 11:34

I had this issue but the only way of getting round it was to wrap expect into a docker image. You can use it like so:

docker run \
    -e NPM_USER=$NPM_USER \
    -e NPM_PASS=$NPM_PASS \
    -e NPM_EMAIL=$NPM_EMAIL \
    bravissimolabs/generate-npm-authtoken \
    > ~/.npmrc

I found that on Windows Server 2012R2, there is some odd behaviour with service accounts. This method worked for me (as part of a Jenkins build, under bash):

cat > ~/.npmrc <<EOL
//my.local.registry:4873/:_authToken="G....................A=="
always_auth=true
registry=http://my.local.registry:4873/
user=aRegisteredUser
EOL

using with npm-cli-login package it worked

# npm install -g npm-cli-login
# npm-cli-login -u myUser -p myPass -e t@ex.com -r http://192.168.56.1:4873

Checking if it is installed or not:

# whereis npm-cli-login
npm-cli-login:
# whereis npm-cli-login | grep '/npm-cli-login' -ic
0

After installation:

# npm install -g npm-cli-login

Check if it is installed:

# whereis npm-cli-login
npm-cli-login: /usr/bin/npm-cli-login
# whereis npm-cli-login | grep '/npm-cli-login' -ic
1

Let's login:

npm-cli-login depends on `snyk`, snyk downloads its own closed source binary 85MB from `https://static.snyk.io/cli/*/snyk-*`. It is too much for npm auto login, Carl =) I would go with expect instead. — puchu, Aug 29 '23 at 08:30
