Creating your mocks

API definition

You can create mock definition file to mock directory. Mock API URL is auto generated by directory path. mock/api-name/@METHOD is mapped to METHOD: http://localhost:3000/mock/api-name METHOD can use get/post/put/patch/delete.

If you need route parameters, can use PARAM directory. mock/api-name/$id/@get is mapped to GET: http://localhost:3000/mock/api-name/:id

Request parser

Request for mock is parsed by user definition parser file. User definition parser file name start with "parser-" and format is yaml or js.

Try create a parser file below, and access to http://localhost:3000/mock/books after restart the instant-mock.

/mock/books/@get/parser-default.yml:

status: 200                   # Response status code.
headers:                      # Response headers.
  Content-Type: application/text
rawBody: 'test body'          # Response body.

Define the response body to other file

You can define response body to a any file.

./mock/books/@get/body.json:

{
  "key": "value"
}

./mock/books/@get/parser-default.yml:

status: 200
headers:
  Content-Type: application/json
body: 'body.json'    # Response body file.

Change a reponse by request

Parser file can define multiple resonse for switing by request. Define request parsing rule to if, and response to then.

Try create a parser file below, and access to http://localhost:3000/mock/books/:id after restart the instant-mock. If :id is "1" then response body is "user 1", and if it is "3" then response is 404.

./mock/books/$id/@get/parser-default.yml:

- if:
    params:
      id: 1
  then:
    rawBody: 'book 1'

- if:
    params:
      id: 2
  then:
    rawBody: 'book 2'

- then:
    status: 404

if is can use params/query/body, and it is "and" condition.

• params: Route parameter.
• query: Query string parameter.
• body: Parsed json body parameter.

Advanced parser

YAML format parser is support simple rule only. Use a js parser if you need more advanced rules.

./mock/shelves/:id/@get/parser-default.js:

exports.default = function (req) {
  return {
    status: 200,
    headers: {
      'content-type': 'application/text',
    },
    rawBody: 'your book is ' + req.params.id,
  };
};

Web console

You can open http://localhost:3000 to view the instant-mock web console. Web console can change parser, and show mock api access logs.
