codeowners-api

Simple module to interact with github codeowners This npm module was implemented mainly to support the chrome extension - codeowners-ext

Note on Github Oauth2 access tokens

In order to get all the teams a user is part of, you need to provide a Github access token. The required permissions are:

• repos:public_repo
• user:read:user
  For private repos you would need to add access to private repos

Quick start

> yarn add codeowners-api

    import {Codeowner} from 'codeowners-api';
    
    const repoParams = {repo: 'my-repo', owner: 'repo-owner'}
    const authParams = {type: 'token', token: 'xxxx'}
    
    const codeOwnersApi = new Codeowner(repoParams, authParams);
    const result = await codeOwnersApi.filterForCodeOwner(
        ['/something/a.py', 'tests/something.js', 'tests/something.txt', 'packages/some/deep/dir/index.tsx'],
        '@elaygl'
    );

    console.log(result) // [ 'tests/something.txt', 'packages/some/deep/dir/index.tsx' ]

API

filterForCodeOwners(paths: string[], users: string[])

Given an array of paths and an array of github users/teams (prefixed with @), returns the paths that these users/teams are the codeowners of.

Example:

 const result = await codeOwnersApi.filterForCodeOwners(
        ['package.json', 'tests/something.js', 'tests/something.txt', 'packages/some/deep/dir/index.tsx'],
        ['@elaygl', '@Soluto/mobile-team']
    );
    console.log(result) // ['package.json']

filterForAuthenticatedUser(paths: string[])

Given an array of paths, returns the paths that this authenticated user is the codeowner of (based on the Auth credentials passed in the constructor). Using GithubAPI, the library will also get all the list of teams that this user is part of, inorder to return the mapping which includes this user, and all his/her teams

Example:

 const result = await codeOwnersApi.filterForAuthenticatedUser(
        ['package.json', 'tests/something.js', 'tests/something.txt', 'packages/some/deep/dir/index.tsx']
    );
    console.log(result) // ['package.json']

codeownersFileExists()

Returns true if a CODEOWNERS file exists for the given github repo

getCodeownersFile()

Returns string of the CODEOWNERS file in the given repo

Testing

> yarn test

Full Example

Based on this CODEOWNERS file:

#This is a comment

* @oreporan
/tests/*.txt @elaygl

# Another Comment!!
/tests/test2/someFile.txt @oreporan

/packages/some/ @elaygl

Will generate this result:

    import {Codeowner} from 'codeowners-api';
    
    const repoParams = {repo: 'my-repo', owner: 'repo-owner'}
    const authParams = {type: 'token', token: 'xxxx'}
    
    const codeOwnersApi = new Codeowner(repoParams, authParams);
    const result = await codeOwnersApi.filterForCodeOwner(
        ['/something/a.py', 'tests/something.js', 'tests/something.txt', 'packages/some/deep/dir/index.tsx'],
        '@elaygl'
    );

    console.log(result) // [ 'tests/something.txt', 'packages/some/deep/dir/index.tsx' ]
