Publish a package using bun

[infodusha]

So basically when I did migration of my packages I has issues when publishing.
Since bun has no publish command you actually have to install npm: bun add -g npm
Therefore, you need to auth and that may be not that clear in CI - NODE_AUTH_TOKEN env no more works when running npm with bun.
I found a solution in the bun codebase.
What you need it to add .npmrc with following content:

//registry.npmjs.org/:_authToken=${NODE_AUTH_TOKEN}

So you can read auth token from env again and everything works.

Now bun supports publish but you will likely still fail in CI publishing - that is because bun uses NPM_CONFIG_TOKEN and does not support NODE_AUTH_TOKEN. So the solution is to simply replace NODE_AUTH_TOKEN by NPM_CONFIG_TOKEN

(and you don't need echo "//registry.npmjs.org/:_authToken=\${NODE_AUTH_TOKEN}" > ~/.npmrc as suggested here or by ChatGPT/GitHub Copilot, this solution is outdated)
