### Synopsis

<!-- AUTOGENERATED USAGE DESCRIPTIONS -->

### Description

Manages the `allowScripts` field in your project's `package.json`, which
records which of your dependencies are permitted to run install scripts
(`preinstall`, `install`, `postinstall`, and `prepare` for non-registry
sources). This command is the recommended way to maintain that field.

Dependency install scripts are blocked by default. Install commands
silently skip lifecycle scripts for any dependency that does not have a
matching entry in `allowScripts`, and end with a list of the packages
whose scripts were skipped so you can review them with this command.

This command only works inside a project that has a `package.json`. Running
it with `--global` (`-g`) fails with an `EGLOBAL` error, since global
installs (`npm install -g`) and one-off executions (`npm exec` / `npx`) have
no project `package.json` to write to. To allow install scripts in those
contexts, use the `--allow-scripts` flag at install time (for example
`npm install -g --allow-scripts=canvas,sharp`) or persist the setting with
`npm config set allow-scripts=canvas,sharp --location=user`.

There are three modes:

```bash
npm approve-scripts <pkg> [<pkg> ...]
npm approve-scripts --all
npm approve-scripts --allow-scripts-pending
```

`<pkg>` matches every installed version of that package. By default the
command writes pinned entries (`pkg@1.2.3`), which keep their approval
narrowed to the specific version you reviewed. Pass `--no-allow-scripts-pin` to write
name-only entries that allow any future version.

`--all` approves every package with unreviewed install scripts in one go.

`--allow-scripts-pending` is read-only: it lists every package whose install scripts
are not yet covered by `allowScripts`, without modifying `package.json`.

`approve-scripts` honours the asymmetric pin rule: if you re-approve a
package whose installed version has changed, the existing pin is rewritten
to track the new installed version. Multi-version statements
(`pkg@1 || 2`) are left alone, since they likely capture intent that
the command cannot infer. Existing `false` entries always win;
`approve-scripts` will not silently re-allow a package you previously
denied.

### Examples

```bash
# Approve all currently-installed install scripts after reviewing them
npm approve-scripts --all

# Approve specific packages, pinned to their installed version
npm approve-scripts canvas sharp

# Approve name-only (any version of this package is allowed)
npm approve-scripts --no-allow-scripts-pin canvas

# Preview which packages still need review
npm approve-scripts --allow-scripts-pending
```
