1. git cli latest version
2. docker latest version
3. npm cli 6.*
4. Node.js LTS v10.*

Note: the following instalation steps have been tested on a MacOS system only, however because most of the commands can be executed via the docker container (as well as locally via npm) it should work on other systems without issues.

1. Open a terminal window and clone this repo: git clone [email protected]:rossanthony/github-miner.git
2. Run setup: npm run docker-setup (this will trigger a download and build of the required docker containers, plus installation of the npm module dependencies)
3. Make a copy of .env.default named .env (at the same root level in the project folder, note: this file is in the .gitignore so it won't be commited to avoid exposing secrets), update the following two lines:

GITHUB_CLIENT_ID=
GITHUB_CLIENT_SECRET=

with credentials from your own OAuth Github app. To obtain these to your github account and go to /settings/developers, for more details on this process see here. Without this step the rate-limit will kick in at 10 requests p/min. Authenticated apps are permitted up to 30 requests p/min. 4. Install the neo4j plugins: npm run install-neo4j-plugins

1. Start mining: npm run mine (local machine) or npm run docker-exec mine (to execute inside the docker container)
2. Import the mined data into Neo4j: npm run insert (local) or npm run docker-exec insert (docker)
3. Explore the data via the locally running instance of Neo4j browser: https://localhost:7474

To import the dependencies for a specific repository use the following command npm run insert <username> <repo>, for example to run it against this repo run:

npm run insert rossanthony github-miner

Once this has run and imported the data, it is possible to run a cypher query like the example below:

MATCH (repo:GitRepo {
	full_name:'rossanthony/github-miner'}
)-[:DEPENDS_ON*]->(dependencies)
RETURN repo, dependencies

This should return all node_modules (direct imports and sub-dependencies) of the project.

For examples of other queries to run see /documentation/queries.md.

• Local: npm run test
• Docker: npm run docker-exec test
