Repo Ranker

Author: Gregory D. Hardy

This app allows you to browse commits on the default branch for a given public Github organization.

Running the App

To run the app you will need to generate a Github personal access token (PAT). The exact permissions your token will need are:

repo
read:packages
read:org
read:public_key
read:repo_hook
user
read:discussion
read:enterprise
read:gpg_key

1. Create a .env file in the root of the project directory
2. Add the REACT_APP_GITHUB_TOKEN environment variable to the .env file

REACT_APP_GITHUB_TOKEN="<YOUR_PERSONAL_ACCESS_TOKEN>"

3. Run npm run start to launch the development server. The app will start on http://localhost:3000/

Running Tests

Test suites can be excuted by running npm run test. Press the A key to ensure all suites are executed.

There are three tests:

Commits.test.tsx
Repositories.test.tsx
OrganizationControler.test.tsx

What Was Built

The following features were specifically built into this project

• Search functionality returns organization by Github login id
• Repositories ranked by descending stargazer count
• First ten (10) repositories and commits fetched by default
• Commits link to commit details on Github.com
• Paginated record fetching on button click
• GraphQL query result caching to minimize trips to the API server
• Controller unit test and View snapshot samples

General Design

An OrganizationController handles the details of fetching data from the Github API. The Repositories and Commits views produced by the ItemFactory component handle display of the repository and commit information. A SearchController component handles user input.

Tooling Used

• Create React App
• React Router
• Apollo Client
• Tailwind CSS & UI
• TypeScript
• Jest

Tooling Choice Considerations

Create React App provided a quick development set up without having to worry about configuration details of Webpack, Babel, and Jest. Apollo Client was chosen for it's convenient GraphQL query caching and merging capabilities. Tailwind CSS & UI was chosen to reduce the time spent on building a functional but beautiful UI. TypeScript was chosen to enforce strict typing and reduce bugs related to ill-constructed interfaces between the app and the GitHub API.
