Project guide

In this project, you'll see the following Midway based practice case (the upper layer uses egg.js) Midway is based on TypeScript development and combines OOP + Class + IoC. midway is similar to nestjs in its design concept

Usage

The following environmental support is required to run the project

Mongo
Redis
Jeager

Installation dependency by docker

docker-compose up -d
docker-compose down

Initializing db

docker exec -it mongo mongosh admin
use admin
db.auth('admin','admin')
use test
db.createUser({user:'admin',pwd:'123456',roles:[{role:'readWrite',db:'test'}]})

Development

$ npm i
$ npm run dev
$ open http://localhost:7001/

Deploy

$ npm start
$ npm stop

npm scripts

Use npm run lint to check code style.
Use npm test to run unit test

Redis

Access using Redis as user login credentials

Redis partition

user:accessToken:${id} Cache user Token information
user:userinfo:${id} Cache user basic information

Jaeger

Jaeger [OpenTracing] (https://opentracing.io/docs/)

This implementation is based on the ctx mechanism and combined with midway's dependency injection to realize non-intrusive spanContext delivery

Implements interface-level sampling by default

span can be manually managed if small particle size sampling is required

ctx.tracerManager.startSpan('SpanName1')
await doSomethine()
ctx.tracerManager.finishSpan()

Interface document

open http://127.0.0.1:7001/swagger-ui/index.html#/

Unit testing

The unit test framework is Mocha. Support the case for . Skip () . Only () combination of optional and to achieve fast, Suitable for scenarios involving complex, coupled business projects
