NPM publishing plugin for auto
npm install @auto-it/npmPublish to NPM.
Works in both a monorepo setting and for a single package.
This plugin is loaded by default when auto is installed through npm.
If you configure auto to use any other plugin this will be lost.
So you must add the npm plugin to your plugins array if you still want NPM functionality.
To publish to npm you will need an NPM_TOKEN set in your environment.
> Warning! Avoid using the prepublishOnly script as it can lead to errors. Read more here.
This plugin is included with the auto CLI so you do not have to install it. To install if you are using the auto API directly:
``bash`
npm i --save-dev @auto-it/npmor
yarn add -D @auto-it/npm
> WARNING: You can only use one "package manager" at a time!
> Mixing them will lead to undesired results.
`json`
{
"plugins": [
"npm",
// or with options
["npm", { "forcePublish": false }]
// other plugins
]
}
> If you're using the noVersionPrefix option you will also need to add tag-version-prefix="" to your .npmrc.v
> Otherwise when npm versions your code the tag it creates will have the and auto will get confused.
The npm plugin works out of the box with lerna in both independent and fixed mode.auto works on a repo basis and should be run from the root of the repo, not on each sub-package.
No additional setup is required.
> Do you have a package in your monorepo you don't want to publish but still want versioned?
> Just set that "private": true you that package's package.json!Options
When running the shipit command auto will try to set your .npmrc token while publishing. To disable this feature you must set the setRcToken to false.
`json`
{
"plugins": [
[
"npm",
{
"setRcToken": false
}
]
]
}
By default auto will force publish all packages for monorepos. To disable this behavior you must set the forcePublish to false.
`json`
{
"plugins": [
[
"npm",
{
"forcePublish": false
}
]
]
}
To force all packages publish with exact versions.
`json`
{
"plugins": [
[
"npm",
{
"exact": true
}
]
]
}
auto will create a changelog for each sub-package in a monorepo.subPackageChangelogs
You can disable this behavior by using the option.
`json`
{
"plugins": [
[
"npm",
{
"subPackageChangelogs": false
}
]
]
}
auto will group changelog lines by sub-packages in a monorepo.monorepoChangelog
You can disable this behavior by using the option.
`json`
{
"plugins": [
[
"npm",
{
"monorepoChangelog": false
}
]
]
}
Whether to create a commit for "next" version.
The default behavior will only create the tags.
`json`
{
"plugins": [
[
"npm",
{
"commitNextVersion": true
}
]
]
}
When publishing packages that require authentication but you are working with an internally hosted npm registry that only uses the legacy Base64 version of username:password.
This is the same as the NPM publish \_auth flag.
For security this option only accepts a boolean.
When this option is set true auto will pass --_auth $NPM_TOKEN to the publish command.$NPM_TOKEN
Set to the "Base64 version of username:password".
`json`
{
"plugins": [
[
"npm",
{
"legacyAuth": true
}
]
]
}
When publishing packages from a folder other than the project root the publishFolder config can be set.
When used with npm generates command similar to npm publish more info can be found here: npm-publish.
When used with lerna in a monorepo, this functionality implements the --contents flag, more info can be found here: lerna publish --contents.
> :exclamation: NOTE: This functionality should be combined with a valid npm Life Cycle script,
> otherwise the version of the produced package will not align with the calculated/expected version generated by auto.
> See Life Cycle Scripts for additional info.
`json`
{
"plugins": [
[
"npm",
{
"publishFolder": "./dist/some-dir"
}
]
]
}
#### Life Cycle Scripts
During the publish routine, this plugin will execute (npm version|npx lerna version), and then immediately follow-up with (npm publish|npx lerna publish). If you're attempting to publish a package from a directory other than the project root, its likely you're doing some sort of repository or package.json manipulation in an attempt to cleanup (remove devDependencies, scripts, fields) or otherwise manually construct your published package. Since this process is likely invoked prior to the version and publish event enacted by this plugin, the version in your processed package.json would not match the new version the plugin is attempting to publish (unless you've accounted for this in some other fashion). This simply means we need to insert ourselves between the version and publish stages of this plugin and re-process or otherwise update the package.json file in our publishFolder.
Appropriate life cycle scripts (which operate after version but before publish) would include [postversion, prepublishOnly, or prepack]. Its worth noting the postversion life cycle script will be enacted in the context of your root package.json file, while prepublishOnly and prepack would be enacted in the context of your publishFolder package.json file.
Example life cycle script which is triggered after (npm version|npx lerna version) and before (npm publish|npx lerna publish):
`
{
"scripts": {
"postversion": "cd
}
}
> :warning: Warning! Use caution when pairing long-running life cyle scripts with auto. Read more here.
Publishing canary versions comes with some security risks.
If your project is private you have nothing to worry about and can skip these, but if your project is open source there are some security holes.
> :warning: This feature works pretty easily/well for single packages. In a monorepo we have to deal with a lot more, and this options should be treated as experimental.
#### Setup
1. Create a test scope that you publish canaries under (ex: @auto-canary or @auto-test)NPM_TOKEN
2. Create a user that only has access to that scope
3. Set the default to a token that can publish to that scope (this is used for any pull request)secure
4. Set up a token that is only accessible on the main fork (still named NPM_TOKEN)
5. Set up alias (only monorepos)
Step 3 might not be possible on your build platform.
The following are the ways the auto team knows how to do it.
If you do not see the method for you build platform, please make a pull request!
Platform Solutions:
- CircleCI Context - Contexts provide a mechanism for securing and sharing environment variables across projects. The environment variables are defined as name/value pairs and are injected at runtime.
`json`
{
"plugins": [
[
"npm",
{
"canaryScope": "@auto-canary"
}
]
]
}
##### Set up alias
If you are managing a non-monorepo you do not have to do anything for this step!
If you manage a monorepo we still have to do handle our packages importing each other.
Since we just changed the name of the package all imports to our packages are now broken!
There are multiple ways to make this work and the solution might be different depending on your build target.
- module-alias - Modifiy node's require for your canary deploys (This is what auto uses). Useful for node packages
- Webpack Aliases Modify scoped requires for webpack based projects.
- babel-plugin-module-resolver - A Babel plugin to add a new resolver for your modules when compiling your code using Babel.
This error will occur when you do not have a NPM_TOKEN set.
Make sure that npm is trying to publish to the correct registry. Force npm/lerna to use the public registry by adding the following to your package.json:
`json``
{
"publishConfig": {
"registry": "https://registry.npmjs.org/",
"access": "public"
}
}
