|
||
It is both a series of command line scripts which you can use to test different states, and an Azure Function App which handles incoming webhooks from the DefinitelyTyped repo. | ||
|
||
This repo is deployed to Azure on every push to master. | ||
To ensure we can handle timeouts on older PRs, there is a [GitHub Action](https://github.com/DefinitelyTyped/dt-mergebot/actions) that runs the bot every 6 hours against [all open PRs](./src/run.ts), and has a bunch of useful flags for running manually too. | ||
|
||
# Setup | ||
|
||
```sh | ||
# Clone it | ||
git clone https://github.com/DefinitelyTyped/dt-mergebot.git | ||
cd dt-mergebot | ||
|
||
# Deps | ||
pnpm install | ||
|
||
# Validate it works | ||
pnpm test | ||
``` | ||
|
||
# How the app works | ||
|
||
There are three main stages once the app has a PR number: | ||
|
||
* Query the GitHub GraphQL API for PR metadata ([`pr-info`](src/pr-info.ts)) | ||
* Create a PR actions metadata object ([`compute-pr-actions`](src/compute-pr-actions.ts)) | ||
* Do work based on the resulting actions ([`execute-pr-actions`](src/execute-pr-actions.ts)) | ||
|
||
# How the bot works | ||
|
||
There is an Azure function in `PR-Trigger` that receives webhooks; this function's job is to find the PR number then it runs the above steps. | ||
|
||
# Running Locally | ||
|
||
You _probably_ don't need to do this. Use test to validate any change inside the src dir against integration tests. | ||
|
||
However, you need to have a GitHub API access key in either: `DT_BOT_AUTH_TOKEN`, `BOT_AUTH_TOKEN` or `AUTH_TOKEN`. | ||
Ask Ryan for the bot's auth token (TypeScript team members: Look in the team OneNote). | ||
Don't run the bot under your own auth token as this will generate a bunch of spam from duplicate comments. | ||
|
||
```sh | ||
# Windows | ||
set BOT_AUTH_TOKEN=xxxxxxxxxxxxxxxxxxxxxxxxxxxx | ||
|
||
# *nix | ||
export BOT_AUTH_TOKEN=xxxxxxxxxxxxxxxxxxxxxxxxxxxx | ||
``` | ||
|
||
Then to run locally you'll need to install the [Azure Functions cli](https://docs.microsoft.com/en-us/azure/azure-functions/functions-run-local?tabs=macos%2Ccsharp%2Cbash). | ||
|
||
# Development | ||
|
||
```sh | ||
# Build | ||
pnpm run build | ||
|
||
# Run the CLI to see what would happen to an existing PR | ||
pnpm run single-info -- [PR_NUM] | ||
# or | ||
pnpm run single-info-debug -- [PR_NUM] | ||
``` | ||
|
||
### If you update any queries | ||
|
||
Run this to update the generate types: | ||
|
||
```sh | ||
# Code-gen the schema | ||
pnpm run graphql-schema | ||
``` | ||
|
||
### If you change project columns or labels | ||
|
||
Run this to update the cached values: | ||
|
||
```sh | ||
# Regenerate src/_tests/cachedQueries.json | ||
pnpm run update-test-data | ||
``` | ||
|
||
# Tests | ||
|
||
```sh | ||
# Run tests, TypeScript is transpiled at runtime | ||
pnpm test | ||
``` | ||
|
||
Most of the tests run against a fixtured PR, these are high level integration tests that store the PR info and then re-run the latter two phases of the app. | ||
|
||
To create fixtures of a current PR: | ||
|
||
```sh | ||
# To create a fixture for PR 43161 | ||
pnpm run create-fixture -- 43161 | ||
``` | ||
|
||
Then you can work against these fixtures offline with: | ||
|
||
```sh | ||
# Watch mode for all tests | ||
pnpm test -- --watch | ||
# Just run fixtures for one PR | ||
pnpm test -- --testNamePattern 44299 | ||
``` | ||
|
||
Run a test with the debugger: | ||
|
||
```sh | ||
node --inspect --inspect-brk ./node_modules/.bin/jest -i --runInBand --testNamePattern 44299 | ||
``` | ||
|
||
Then use "Attach to Process ID" to connect to that test runner | ||
|
||
If your changes require re-creating all fixtures: | ||
|
||
```sh | ||
pnpm run update-all-fixtures | ||
``` | ||
|
||
Be careful with this, because PRs may now be in a different state e.g. it's now merged and it used to be a specific | ||
weird state. | ||
|
||
## Running with real webhooks | ||
|
||
You need a tool like [ngrok](https://ngrok.com) to expose a URL from the [webhooks section](https://github.com/DefinitelyTyped/DefinitelyTyped/settings/hooks/new) on DT. | ||
|
||
Start two terminal sessions with: | ||
|
||
- `yarn watch` (for TypeScript changes) | ||
- `yarn start` (for the app) | ||
|
||
Then start a third with your localhost router like ngrok: | ||
|
||
- `ngrok http 7071` | ||
