VTuber API

A Mongoose / GraphQL based API to serve VTuber information from multiple platforms.

Development

• Prerequisites:
  • Have node installed.
  • Have MongoDB and Memcached installed locally.
    • Optional: Download MongoDB Compass to access your database with a GUI.
  • Have a Google Cloud Project API Key with Youtube API enabled.
  • Setup some channels first before starting.

Installation

# Install dependencies and create your .env copy
$ npm i
$ cp .env.sample .env
# Make sure to adjust your .env file before continuing!

# Create a directory called organizations inside channels, then move the files from
# channels/default to channels/organizations, or check the template.json file to see how to create your own list.

# After populating channels/organizations, run:
$ npm run channel-manager
# OR
$ npm run init

# If all things went well, you can then start the api.
$ npm start
