Mock Node Server

A simple node server that can run in a docker container that can be used for simple testing.

It console.log all requests received including the body. An optional rules file can be specified to inidcate how any request should be handled. If not provided it responds with Http 200

Rule File

Two types of rules file is supported

• json (v1.0.0)
• toml (v2.0.0)

The advantage of using toml is that it support multilines without escaping. It is recommened to use toml format unless you love json and escaping too much :).

Toml format (Supported in v2.0.0)

  ["/a/b/c"] # the path
  body = '''
     {"text": "I love toml"}
  '''
  headers = {content-type = "application/json"}
  responseCode = 200

  ["a/b/d"] # another path    

Json Format (Only supported in v1.0.0)

The rule file is a simple json file that has the following fields.

• path - specify the path for the rule. The mock server will use simple String.find to see if the request path matches and if it does then the specific entry will be used. No fancy regex at the moment.
• body - response body
• headers - response headers
• responseCode - Http Response code

No validation is done for the rules file. Sample rule file

[
  {
    "path": "/abc",
    "body": "hello world",
    "headers": [{"key": "content-type", "value": "text"}, {"key" : "abc", "value": "def"}],
    "responseCode" : 200
  },
  {
    "path": "/def",
    "body": "hello world 2",
    "headers": [{"key": "content-type", "value": "text"}, {"key" : "abc", "value": "def"}],
    "responseCode" : 400
  }
]

Creating image locally

docker build -t "node-mock-server" .

Running

docker pull tabiul/node-mock-server:v1.0.0 (json) docker pull tabiul/node-mock-server:v2.0.0 (toml)

The server takes the following arguments

• -p : specify port, defaults to 9080
• -f : path to rules file, default no file

Running in docker

docker run -it -p 9080:9080 -v /path/to/rules.json:/rules.json node-mock-server:v1.0.0 -f /rules.json (json)

docker run -it -p 9080:9080 -v /path/to/rules.toml:/rules.toml node-mock-server:v2.0.0 -f /rules.toml (toml)
