A simple TODO app

A simple TODO app that uses Buf Connect, JWTs for authentication, OTEL for tracing, and sqlc and Postgres for storage.

Try it out

docker compose up -d will run Postgres, Jaeger and the TODO app.

Prerequisite

Create a JWT with the sub claim set to a user id and set the JWT_SECRET env var, or just use

export TOKEN="eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJtcl9yb2JvdG8ifQ.oUD_0r5Q1H_akjeJFWYAxbcr2fckBEb7M25wVJw432Y"

with the default secret.

Usage

$ curl -XPOST http://localhost:8080/todoapp.v1.TodoAppService/Create \
-H "Authentication: Bearer $TOKEN" \
