How toConfigure scoped private packages in Bun

Create a bunfig.toml file and put the following code:

bunfig.toml
[install.scopes]
"@scope" = { token = "REGISTRY_TOKEN", url = "REGISTRY_URL" }

Replace @scope with your package scope, e.g. @company-name.

Replace REGISTRY_TOKEN with an actual token your registry provides you, you can use $TOKEN (with the leading $) to reference a environment variable, useful to avoid hard coding it specially on public repos and it can be set in your deployment platform too.

Then replace REGISTRY_URL with the URL of the registry that holds your package, e.g. https://npm.pkg.github.com can be used to point to GitHub Package Registry which can be used for private package within an organizations.

And that's it, now you can do bun add @scope/package and it should work.

If you're on v1.1.18 on Bun, you can also just use .npmrc file.

.npmrc
@scope:registry=REGISTRY_URL
//REGISTRY_URL/:_authToken=REGISTRY_TOKEN

Same as with bunfig.toml, you can use $TOKEN as replacement of REGISTRY_TOKEN to use an environment variable.
