It supports all package specifier syntax that `npm install` and its ilk support. It transparently caches anything needed to reduce excess operations, using [`cacache`](https://npm.im/cacache). ## Install `$ npm install --save pacote` ## Table of Contents * [Example](#example) * [Features](#features) * [Contributing](#contributing) * [API](#api) * [`manifest`](#manifest) * [`packument`](#packument) * [`extract`](#extract) * [`tarball`](#tarball) * [`tarball.stream`](#tarball-stream) * [`tarball.toFile`](#tarball-to-file) * ~~[`prefetch`](#prefetch)~~ (deprecated) * [`clearMemoized`](#clearMemoized) * [`options`](#options) ### Example ```javascript const pacote = require('pacote') pacote.manifest('pacote@^1').then(pkg => { console.log('package manifest for registry pkg:', pkg) // { "name": "pacote", "version": "1.0.0", ... } }) pacote.extract('http://hi.com/pkg.tgz', './here').then(() => { console.log('remote tarball contents extracted to ./here') }) ``` ### Features * Handles all package types [npm](https://npm.im/npm) does * [high-performance, reliable, verified local cache](https://npm.im/cacache) * offline mode * authentication support (private git, private npm registries, etc) * github, gitlab, and bitbucket-aware * semver range support for git dependencies ### Contributing The pacote team enthusiastically welcomes contributions and project participation!

Manifest objects are similar and based on the `package.json` for that package, but with pre-processed and limited fields. The object has the following shape: ```javascript { "name": PkgName, "version": SemverString, "dependencies": { PkgName: SemverString }, "optionalDependencies": { PkgName: SemverString }, "devDependencies": { PkgName: SemverString }, "peerDependencies": { PkgName: SemverString }, "bundleDependencies": false || [PkgName], "bin": { BinName: Path }, "_resolved": TarballSource, // different for each package type "_integrity": SubresourceIntegrityHash, "_shrinkwrap": null || ShrinkwrapJsonObj } ``` Note that depending on the spec type, some additional fields might be present. For example, packages from `registry.npmjs.org` have additional metadata appended by the registry. ##### Example ```javascript pacote.manifest('pacote@1.0.0').then(pkgJson => { // fetched `package.json` data from the registry }) ``` #### `> pacote.packument(spec, [opts])` Fetches the *packument* for a package. Packument objects are general metadata about a project corresponding to registry metadata, and include version and `dist-tag` information about a package's available versions, rather than a specific version. It may include additional metadata not usually available through the individual package metadata objects. It generally looks something like this: ```javascript { "name": PkgName, "dist-tags": { 'latest': VersionString, [TagName]: VersionString, ... }, "versions": { [VersionString]: Manifest, ... } } ``` Note that depending on the spec type, some additional fields might be present. For example, packages from `registry.npmjs.org` have additional metadata appended by the registry. ##### Example ```javascript pacote.packument('pacote').then(pkgJson => { // fetched package versions metadata from the registry }) ``` #### `> pacote.extract(spec, destination, [opts])` Extracts package data identified by `` into a directory named ``, which will be created if it does not already exist. If `opts.digest` is provided and the data it identifies is present in the cache, `extract` will bypass most of its operations and go straight to extracting the tarball. ##### Example ```javascript pacote.extract('pacote@1.0.0', './woot', { digest: 'deadbeef' }).then(() => { // Succeeds as long as `pacote@1.0.0` still exists somewhere. Network and // other operations are bypassed entirely if `digest` is present in the cache. }) ``` #### `> pacote.tarball(spec, [opts])` Fetches package data identified by `` and returns the data as a buffer. This API has two variants: * `pacote.tarball.stream(spec, [opts])` - Same as `pacote.tarball`, except it returns a stream instead of a Promise. * `pacote.tarball.toFile(spec, dest, [opts])` - Instead of returning data directly, data will be written directly to `dest`, and create any required directories along the way. ##### Example ```javascript pacote.tarball('pacote@1.0.0', { cache: './my-cache' }).then(data => { // data is the tarball data for pacote@1.0.0 }) ``` #### `> pacote.tarball.stream(spec, [opts])` Same as `pacote.tarball`, except it returns a stream instead of a Promise. ##### Example ```javascript pacote.tarball.stream('pacote@1.0.0') .pipe(fs.createWriteStream('./pacote-1.0.0.tgz')) ``` #### `> pacote.tarball.toFile(spec, dest, [opts])` Like `pacote.tarball`, but instead of returning data directly, data will be written directly to `dest`, and create any required directories along the way. ##### Example ```javascript pacote.tarball.toFile('pacote@1.0.0', './pacote-1.0.0.tgz') .then(() => /* pacote tarball written directly to ./pacote-1.0.0.tgz */) ``` #### `> pacote.prefetch(spec, [opts])` ##### THIS API IS DEPRECATED. USE `pacote.tarball()` INSTEAD Fetches package data identified by ``, usually for the purpose of warming up the local package cache (with `opts.cache`). It does not return anything. ##### Example ```javascript pacote.prefetch('pacote@1.0.0', { cache: './my-cache' }).then(() => { // ./my-cache now has both the manifest and tarball for `pacote@1.0.0`. }) ``` #### `> pacote.clearMemoized()` This utility function can be used to force pacote to release its references to any memoized data in its various internal caches. It might help free some memory. ```javascript pacote.manifest(...).then(() => pacote.clearMemoized) ``` #### `> options` `pacote` accepts [the options for `npm-registry-fetch`](https://npm.im/npm-registry-fetch#fetch-options) as-is, with a couple of additional `pacote-specific` ones: ##### `opts.dirPacker` * Type: Function * Default: Uses [`npm-packlist`](https://npm.im/npm-packlist) and [`tar`](https://npm.im/tar) to make a tarball. Expects a function that takes a single argument, `dir`, and returns a `ReadableStream` that outputs packaged tarball data. Used when creating tarballs for package specs that are not already packaged, such as git and directory dependencies. The default `opts.dirPacker` does not execute `prepare` scripts, even though npm itself does. ##### `opts.enjoy-by` * Alias: `opts.enjoyBy`, `opts.before` * Type: Date-able * Default: undefined If passed in, will be used while resolving to filter the versions for **
