Dapr components go SDK POC

This repository is a POC of a SDK for Dapr gRPC Components (a.k.a pluggable components)

Running examples

Start by running ./run.sh inside /examples folder. It will start the daprd runtime with pluggable components version + default in memory state store implementation from components-contrib, use ./run.sh redis to run redis instead.

Run ARGS=--no-cache ./run.sh if you want to rebuild the docker image.

See it working:

curl -X POST -H "Content-Type: application/json" -d '[{ "key": "name", "value": "Bruce Wayne", "metadata": { "ttlInSeconds": "60"}}]' http://localhost:3500/v1.0/state/default

curl http://localhost:3500/v1.0/state/default/name

Implementing a Pluggable State Store component

To create your own implementation:

1. Create a new folder under /examples
2. Implement a stateStore using the sdk
3. create a component.yml (copying from other sources and changing the component-specific metadata)
4. Run ./run.sh your_folder_goes_here

This will build your component and bootstrap the dapr runtime with the default options.

Getting started

Creating a new component is nothing more than implement a StateStore interface and Run the dapr component server.

package main

import (
	dapr "github.com/mcandeia/dapr-components-go-sdk"
)

func main() {
	dapr.MustRun(dapr.UseStateStore(MyComponentGoesHere{}))
}
