+# Registry Only Dependencies
+
+## Summary
+
+When auditing dependencies with `npm audit`, the npm CLI should have a mechanism for communicating (and optionally failing on) dependencies that _do not_ come from a registry, like a [git URL](https://docs.npmjs.com/cli/v7/configuring-npm/package-json#git-urls-as-dependencies).
+
+## Motivation
+
+In an effort to give users of npm more insight and transparency into the packages they are installing, knowing that a package is _not_ coming from a registry and thus is susceptible to mutability and related supply chain attacks from that vector, seems like a meaningful heuristic missing from the package manager.
+
+Thus, npm should afford various levels of messaging and erroring through a flag to accommodate users of npm looking to gain this insight from their dependency graph.
+
+## Detailed Explanation
+
+For example a _package.json_ like this
+```json
+{
+  "dependencies": {
+    "@babel/cli": "^7.4.0",
+    "eslint": "git+https://github.com/eslint/eslint.git"
+  }
+}
+```
+
+Would trigger a message to the console for **eslint** if the `warn` value was passed when running `npm audit`.
+
+```sh
+$ npm audit --only-registry-deps=warn
+
+found 1 vulnerabilities
+
+...
+```
+
+## Rationale and Alternatives
+
+It could be argued that a user could write a script themselves that does all the look-ups and resolution from a given _package.json_ or _package-lock.json_ to vet their dependencies that way, potentially reusing arborist in a similar manner to how the CLI uses it.
+
+However, when this issue was raised no other alternatives were suggested at the time, even the one above, so it seems that most feel (implicitly at least) that the package manager is in the best position to vet the source of dependencies before they can be installed, and communicate that information to the user.
+
+## Implementation
+
+When running `npm audit`, the user should be informed if _any_ dependency in the tree is not using a valid [semver range](https://docs.npmjs.com/cli/v7/configuring-npm/package-json#dependencies) and emit a message to the terminal communicating that information.  Effectively, the audit messaging should get raised if any of the dependencies qualify as a [`type` of **git** or **remote* dependency per this document](https://github.com/npm/npm-package-arg#result-object).
+
+The flag would allow three values that the user could use to influence the level of messaging and command line behavior:
+```sh
+$ npm audit --only-registry-deps=silent|warn|fail
+
+found N vulnerabilities
+
+...
+```
+
+From a CLI perspective, this could easily (ideally) be delegated to the `npm query` command.
+```sh
+$ npm query ":is(:type(git,remote))"
+```
+
+### Options
+
+#### Silent
+Same behavior as it is now in the CLI effectively, in that there is no messaging in regards to the source of a dependency.
+
+```sh
+$ npm audit --only-registry-deps=silent
+```
+
+#### Warn (default)
+Emits a log message to the terminal indicating that a dependency is referencing a non-registry URL.  
+```sh
+$ npm audit --only-registry-deps=warn
+
+found 1 vulnerabilities
+
+npm WARN eslint is not installed from a trusted source; using tarball URL <URL>.  Please read more about our guidelines at https://docs.npmjs.com/cli/....
+```
+
+This would be the default value for the command with or without a value passed to the flag.
+```sh
+# both would behave the same way
+$ npm audit --only-registry-deps
+$ npm audit --only-registry-deps=warn
+```
+
+#### Fail
+Emits an error level log to the terminal indicating that a dependency has a non-registry URL AND exits the process with an exit code.
+
+```sh
+$ npm audit --only-registry-deps=fail
+
+found 1 vulnerabilities
+
+npm ERROR eslint is not installed from a trusted source; using tarball URL <URL>.  Please read more about our guidelines at https://docs.npmjs.com/cli/....
+```
+
+### Messaging
+
+In addition to calling out these types of specifiers numerically, it would be good to have the messaging include information about the dependency graph, similar to the `npm why` or `npm explain`.  This is important as users will want to be able to use `overrides` for those cases which they don't have direct control over and / or report upstream.
+
+For example, using the above **eslint** example, a more complete output might look like this:
+```sh
+$ npm audit --only-registry-deps=warn
+
+found 1 vulnerabilities
+
+npm WARN eslint is not installed from a trusted source; using tarball URL <URL>.  Please read more about our guidelines at https://docs.npmjs.com/cli/....
+
+eslint@6.8.0 dev
+node_modules/eslint
+  dev eslint@"^6.8.0" from the root project
+
+...
+```
+
+### Install
+It is understood that `npm install` leverages `npm audit` but I believe the output of `npm audit` does not directly influence the behavior of `npm install`, say in the case using the `fail` option here.
+
+If possible, it would be great for `npm install` to fail if `npm audit` fails.
+```sh
+$ npm install --fail-on-audit
+```
+
+### Documentation
+In addition to being added to the `npm audit` docs, this behavior should probably be called out or referenced in other relevant area(s) of the CLI documentation, specifically in the [dependencies section of the docs](https://docs.npmjs.com/cli/v7/configuring-npm/package-json#git-urls-as-dependencies), where non semver range versions like git URLs are discussed.
+
+## Prior Art
+
+As far as I know, while other package managers allow installing from URLs and git repositories, none of them call it out as a potential anti-pattern or area of caution.
+- **yarn**: [`add`](https://classic.yarnpkg.com/en/docs/cli/add#toc-adding-dependencies), [`install`](https://yarnpkg.com/cli/install)
+- **pnpm**: [`add`](https://pnpm.io/cli/add#install-from-git-repository), [`install`](https://pnpm.io/cli/install)
+
+This seems like a worthwhile area for npm to be the first mover.
+
+To demonstrate, if you see [this demo repo](https://github.com/thescientist13/npm-query-registry-only-deps-rfc-demo) and follow the steps to `npm link` with a version that has `npm query`, you will see output for **eslint** but not **babel**, which is the desired outcome in this situation given that _package.json_ has eslint as a `git` dependency.
