Ender Repository Build Status

A component of the Ender CLI, providing an interface to npm, all npm interaction goes through here so it's safely abstracted away from the rest of the code.

The important parts are the setup() and packup() methods which must wrap around any call to an npm command. If you don't do a setup() then you'll get an error, if you don't do a packup() then you'll likely have a hanging-process.

These two methods manage npm initialisation and also manage an npm logfile that goes into /tmp/ender_npm_... If packup() is called with a falsy first arg then the log file is deleted, otherwise it is left alone for debugging.

Note that multiple npm commands can be run between setup() and packup(), they only need to be done once per app execute.

This repository may be used as a base for providing additional (non-npm) repositories for the Ender CLI.

setup() must be called prior to performing any repository operations. It will also create a 'node_modules' directory in the current working directory if one doesn't already exist. If it has previously been called within the current executing process the callback will be executed immediately.

enderRepository.packup(wasError, callback)

packup() should be called when the repository is no longer required. The wasError boolean argument is used to dictate whether the log file collected from the underlying repository, npm, should be kept, otherwise it is automatically removed., callback)

search() is a simple interface to the standard npm search command.

Note that this is a generic npm search, not a specific Ender search, the filtering is done upstream (at the moment).

enderRepository.install(packages, callback)

install() will install the given packages from npm. The callback is given an object containing properties for the installed tree, a pretty version of the tree and a list of installed packages resulting from the command.

enderRepository.uninstall(packages, callback)

uninstall() uninstalls the given packages using npm.


If you install with npm install ender-repository -g (why would you?) then you'll get an ender-repository executable that will perform install, uninstall and search commands.


Contributions are more than welcome! Just fork and submit a GitHub pull request! If you have changes that need to be synchronized across the various Ender CLI repositories then please make that clear in your pull requests.


Ender Repository uses Buster for unit testing. You'll get it (and a bazillion unnecessary dependencies) when you npm install in your cloned local repository. Simply run npm test to run the test suite.
