Initial Setup

Create Discord Application

1. Create a new Application

2. Enable Privileged Gateway Intents under Bot

3. Invite to server with https://discord.com/oauth2/authorize?client_id=<client_id>&permissions=536870912&scope=applications.commands%20bot

   Note: Replace <client_id> with Application ID

4. After deploying the bot to AWS using either npm run deploy or npm run deploy:prod, paste InteractionsEndpoint into Interactions Endpoint URL under General Information

Configuration

Set environment configuration config.json

{
  "aws_region": "<AWS REGION>",
  "riot_key": "<RIOT API KEY>",
  "discord_public_key": "<DISCORD PUBLIC KEY>",
  "application_id": "<DISCORD APPLICATION ID>",
  "token": "<DISCORD BOT TOKEN>"
}

• aws_region - Region that AWS resources will be deployed to
• riot_key - obtained from Riot Developer Portal
• discord_public_key - found in Discord Developer Portal under General Information
• application_id - found in Discord Developer Portal under General Information
• token - found in Discord Developer Portal under Bot > Reset Token

Bot Deployment

Startup

The bot is configured to be able to deploy to multiple stages. This changes configurations in the AWS stack.

• npm run deploy - deploy dev stack, returns InteractionsEndpoint
• npm run deploy:prod - deploy prod stack, returns InteractionsEndpoint, URL

Production Deployment

Create Redirect

1. In the Discord Application on Discord Developer Portal under OAuth2, create a redirect URL using URL/load

   The redirect URL will look like this https://abcdefghijklm.cloudfront.net/load

2. Under Authorization Method, choose In-app Authorization

3. Enable Scopes: bot, application.commands

4. Enable Bot Permissions: Manage Webhooks

Integrate with GitHub Actions

Create IAM Role

Instructions to deploy SST apps using GitHub Actions can be found here

• aws-github-actions

Create Secrets

Automated Setup

1. Set environment configuration config.actions.json

{
  "pat": "<GITHUB TOKEN>",
  "owner": "<GITHUB REPO OWNER>",
  "repo": "<GITHUB REPO>",
  "aws_account_id": "<AWS ACCOUNT ID>",
  "aws_region": "<AWS REGION>",
  "riot_key": "<RIOT API KEY>",
  "dev": {
    "discord_public_key": "<DISCORD PUBLIC KEY>",
    "application_id": "<DISCORD APPLICATION ID>",
    "token": "<DISCORD BOT TOKEN>"
  },
  "prod": {
    "discord_public_key": "<DISCORD PUBLIC KEY>",
    "application_id": "<DISCORD APPLICATION ID>",
    "token": "<DISCORD BOT TOKEN>"
  }
}

2. In configs, create secrets used by GitHub Actions using npm run start

Manual Setup

1. In the repo, under Settings > Secrets and variables > Actions, create three new repository secrets

   • AWS_ACCOUNT_ID
   • AWS_REGION
   • RIOT_KEY

2. Repeat step 1 for Secrets and variables > Dependabot

3. Additionally, create a new environment called dev and create three new environment secrets

   • APPLICATION_ID
   • DISCORD_PUBLIC_KEY
   • TOKEN

4. Repeat step 3 for prod
