.dat wire

.dat wire is a monorepo for the trade-wire project. I'm not happy with how I designed the trade-wire project, so this is a full rewrite with microservice design implementation.

The project is 100% written in Go.

How to run it on your machine

Prequisites:

• Consul
• Golang

Consul Configuration

You will need to setup consul on your system to be able to run this project, see docs here. You will also need to register the services below:

• datwire-gateway
• datwire-auth
• datwire-users

Here's a consul service definition sample:

{
  "service": {
    "name": "datwire-gateway",
    "tags": ["golang", "datwire"],
    "address": "http://127.0.0.1",
    "port": 3001
  }
}

Typically, you should have a /etc/consuld dir as a config dir. Your config dir should look like this:

/etc/consul.d
├── datwire-auth.json
├── datwire-gateway.json
└── datwire-users.json

So to start a local dev agent, simply run:

consul agent -dev -ui -node=local-dev -config-dir=/etc/consul.d

I like using the web UI to monitor my services, so I included the -ui flag.

Consul KV

This project requires a Consul KV, specifically to store and fetch hash string for tokenization op. Run:

consul kv put datwire/config/hashString [SHA256 KEY HASH]

You can generate the hash via this site: https://www.liavaag.org/English/SHA-Generator/HMAC/

Then run:

consul kv get datwire/config/hashString

to verify.

The consul integration is far from finished, there's a lot of work to be done, so stay tuned!

Tests

To run existing tests simply run: go test -v ./... for now.

Design

note: I'll insert some sort of graph here

TODOs

I'm currently using Asana for my issue tracking and planning. I will eventually move to github issues after its initial public release.

• Service config abstraction
• API Gateway
• Integration tests (gateway tests)
• Test scripts
• Runner scripts
• Validation (struct validation)
• JWT claims should have expiration (1 week?)
• Auth service should have a refresh token method
• Consul integration for service discovery
• Implement Gokit microservice design principles

...and many more that I'll have to add as I go along!
