This is a Redis starter template for Go:

• Redis Cloud
• Echo

Requirements

• make
• go>=1.26.1
• docker
  • Optional

Getting started

Copy and edit the .env file:

cp .env.example .env

Your .env file should contain the connection string you copied from Redis Cloud. The additional settings are optional:

• APP_ENV defaults to development and also accepts test or production
• LOG_LEVEL defaults to info
• LOG_STREAM_KEY defaults to logs

If APP_ENV is unset, NODE_ENV is accepted as a fallback alias.

Your .env.docker file will look similar to .env, but should use the appropriate docker internal URLs. Here is an example:

HOST_PORT=8081
REDIS_URL="redis://redis:6379"

Next, spin up docker containers:

make docker

You should have a server running on http://localhost:<host-port> where HOST_PORT comes from .env.docker (default is 8081). The app still listens on the internal PORT value (default 8080). You can test the following routes:

1. GET /api/todos - Gets all todos
2. GET /api/todos/:id - Gets a todo by ID
3. GET /api/todos/search?[name=<name>]&[status=<status>] - Search for todos by name and/or status
4. POST /api/todos - Create a todo with { "name": "Sample todo" }
5. PATCH /api/todos/:id - Update todo by ID with { "status": "todo|in progress|complete" }
6. DELETE /api/todos/:id - Delete a todo by ID

Running tests

There are unit and Docker-backed integration tests that can be run with the following command:

make test

These tests setup and teardown on their own with Testcontainers. If you want to skip the Docker-backed coverage, run:

make test-short

Running locally outside docker

To run the development server outside of docker:

make dev

Other Scripts

Run make to see the list of available commands. Application and request logs are written to stdout and also appended to the Redis stream named by LOG_STREAM_KEY.

Connecting to Redis Cloud

If you don't yet have a database setup in Redis Cloud get started here for free.

To connect to a Redis Cloud database, log into the console and find the following:

1. The public endpoint (looks like redis-#####.c###.us-east-1-#.ec2.redns.redis-cloud.com:#####)
2. Your username (default is the default username, otherwise find the one you setup)
3. Your password (either setup through Data Access Control, or available in the Security section of the database page.

Combine the above values into a connection string and put it in your .env and .env.docker accordingly. It should look something like the following:

REDIS_URL="redis://default:<password>@redis-#####.c###.us-west-2-#.ec2.redns.redis-cloud.com:#####"

Run the tests to verify that you are connected properly.
