UnServ - stub-server with reverse proxy

Simple tool for developers to mock REST API without being dependent on any backend applications or servers.

Features

• simple endpoint creation
• reverse proxy (ability to redirect the endpoint request to a real working server)
• HTTP server (./build/index.html and ./build/static folder by default)

Installation

$ go get -u github.com/Joker/unserv

Example

Make API

If you want to make an endpoint on http://localhost:8080/api/v1/question/
you should create a file ./stub/api/v1/question.json in a file structure similar to this one:

$ tree

.
├── proxy
├── src
│   ├── App.js
│   └── App.scss
└── stub
    └── api
        ├── users.json
        └── v1
            └── question.json

$ cat ./stub/api/v1/question.json

{
    "answer": 42
}

$ unserv

server start on:  http://localhost:8080

endpoints:
  http://localhost:8080/api/users
  http://localhost:8080/api/v1/question

Response

$ curl http://localhost:8080/api/v1/question/

{
    "answer": 42
}

Proxy example

If you want redirect the endpoint request to a real working server move endpoint file to the ./proxy folder:

$ mkdir -p ./proxy/api/v1/
$ mv ./stub/api/v1/question.json ./proxy/api/v1/

$ tree

.
├── build
│   ├── index.html
│   └── static
│       └── bundle.js
├── proxy
│   └── api
│       └── v1
│           └── question.json
├── src
│   ├── App.js
│   └── App.scss
└── stub
    └── api
        └── users.json

$ unserv -proxy https://realserver.url

server start on:  http://localhost:8080

endpoints:
  http://localhost:8080/api/users


reverse on:  https://realserver.url

proxy url:
  http://localhost:8080/api/v1/question =>
      https://realserver.url/api/v1/question

Response

$ curl http://localhost:8080/api/v1/question/

{
    "answer": 2084
}
