rewrite-shrinkwrap-urls

Rewrite URLs in npm-shrinkwrap.json or package-lock.json

Build Status Coverage Status Greenkeeper badge

Sometimes it's necessary to update the "resolved" URLs in an npm-shrinkwrap.json file or a package-lock.json file - for instance, when you want to point all packages to a private npm registry like npm Enterprise.

This package provides a tool to do just that. It comes with a convenient CLI, but it can be easily used as a module in some other grander logic as well.

Install and Usage

CLI

Install as global (binary) module:

$ npm install -g rewrite-shrinkwrap-urls

View help content:

$ rewrite-shrinkwrap-urls --help
Usage: rewrite-shrinkwrap-urls [npm-shrinkwrap.json] -r <registry> [options]
 
Arguments:
  [npm-shrinkwrap.json]  The input shrinkwrap file containing urls to
                         rewrite. You can omit this if --stdin is used.
                         [file] [default: npm-shrinkwrap.json]

Options:
  -f, --file <output>  Path of file to write modified shrinkwrap to,
                       defaults to input file
                       [file]
 
  -i, --stdin          Read shrinkwrap file contents from stdin

Rewrite all URLs in the current directory's npm-shrinkwrap.json, pointing to the private registry at https://private-registry:

$ rewrite-shrinkwrap-urls -r https://private-registry

The equivalent command for a package-lock.json file would be:

$ rewrite-shrinkwrap-urls package-lock.json -r https://private-registry

Read npm-shrinkwrap-OLD.json and write the modified content to npm-shrinkwrap-NEW.json:

$ rewrite-shrinkwrap-urls npm-shrinkwrap-OLD.json -r https://private-registry -f npm-shrinkwrap-NEW.json

Read shrinkwrap file from stdin and output the modified content to stdout:

$ rewrite-shrinkwrap-urls -r localhost:8080 -i < npm-shrinkwrap.json
$ cat npm-shrinkwrap.json | rewrite-shrinkwrap-urls -r localhost:8080 -

Module

Install to local node_modules directory and add dependency to package.json:

$ npm install --save rewrite-shrinkwrap-urls

Use the module to synchronously modify an object in-place:

// require the module
var rewriteShrinkwrapUrls = require('rewrite-shrinkwrap-urls')
 
// read shrinkwrap object into memory
var shrinkwrap = JSON.parse(require('fs').readFileSync('npm-shrinkwrap.json', { encoding: 'utf8' }))
 
// modify the shrinkwrap object synchronously
rewriteShrinkwrapUrls(shrinkwrap, { newBaseUrl: 'https://private-registry' })
 
// do something with shrinkwrap
console.log(shrinkwrap)

API

rewriteShrinkwrapUrls(shrinkwrap, opts)

Arguments

  • shrinkwrap: object

    Content from a shrinkwrap or package-lock file, as an object in memory.

  • opts: object

    Options object.

Options

  • newBaseUrl: string

    Base URL of new registry to point package URLs at. Default is 'http://localhost:8080'.

  • public: boolean

    Whether to use public registry style URLs or not. A public registry tarball URL looks like https://registry.npmjs.org/through/-/through-2.3.8.tgz while a private registry tarball URL looks like http://localhost:8080/t/through/_attachments/through-2.3.8.tgz. Default is false (use private registry URL style).

  • transformer: function

    A function that will be called for each modified URL, allowing any custom check or modification to be done. The default function simply returns the newUrl.

    Arguments:

    • newUrl: string
    • oldUrl: string
    • packageName: string
    • version: string

    Returns the desired URL as a string

  • syncFrom: boolean

    Whether to sync the "from" field with the "resolved" field for each dependency in the shrinkwrap content. Syncing them means that both fields will updated/rewritten to the new URL.
