snyk-task

A web service that, given a name of an npm package returns its dependent packages.

Installation

npm install

Run

Server

npm run watch-server

Request

GET to /packages/{name}/{versionOrTag}/tree Default port is 5745

The response should look like this:

{
  name: "name",
  version: "version",
  key: "key",
  dependencies: [
    {name: "name1", "version: "version1", ...}
    ...
  ]
}

• name - The package name (e.g. snyk-task)
• version - The package version (e.g. 1.0.0)
• key - The db key (e.g. snyk-task@1.0.0)
• dependencies - The dependencies of the package. Usually contains an array of dependencies ([] if there aren't any). If an error has occured when asking for the package's data it will be an empty object ({}). It'll also be an empty object if the server has reached the level to fetch to.

Further Notes

• With each dependency, a request to the npm-registry is performed. The returned data is being cached to a redis database (default port is 6379). In order to free up the db just npm run clean-cache.
• The server returns the dependencies tree of a package, considering both dependencies and devDependencies.

Future Features

• Add tests.
• Add /packages/{name}/{versionOrTag}/list to return a simple list of dependencies rather than a tree.
• Add a proper logger.
• Add more specific validations to make the request fully covered.
• Make a boolean for fetchDependencies and fetchDevDependencies.
• Make the level to fetch to a configurable variable.
• Decide on a valid and more relevant version when a version range is requested. Currently it just chooses the minimal version possible, i.e. ~1.0.0 will be 1.0.0.
