Just a simple mock server!
Install
npm i --save mqk-mock-server
Set up mock_home
Create a folder as mock_home
. mock_home
folder should be in following structure:
mock_home
|
|--data
| |
| |--[api-controller-folder-name]
| |
| |--_default.js | _default.ts
| |--[api-scenario-file-name]
|
|--preset
| |
| |--[preset-file-name]
|
|--routing
| |
| |--[route-file-name]
|
|--msconfig.json
(Optional) Use mqk cli to create mock server
For mqk cli usage see mqk-cli
# install cli tool
npm i -g mqk-cli
# install mock server template
npm i -g mqk-template-mock-server@latest
# create mock server instance
mqk g
# select mock-server
# created!
Route file
A route file should export an array of Route
settings.
interface Route {
path: string | string[];
methods: HTTP_METHOD[];
controller: string;
}
For example
export default [{
path: '/user',
methods: ['GET'],
controller: 'user-list',
}, {
path: '/user/:id',
methods: ['GET'],
controller: 'user',
}, {
path: ['/user', '/user-create'],
methods: ['POST'],
controller: 'user-create'
}];
Default Scenario Setting
Make sure there is a [_default.js | _default.ts]
file under each [api-controller-folder-name]
folder. It simply export the default scenario name/names of API Scenario File
.
For example
export default 'success';
If an array of scenarios is used, mock server will respond with senario data in sequence.
export default ['success', 'failed'];
API Scenario File
An API Scenario File
should return meta data for an API (regard as API Setting
). API Scenario File
can be in one of following format:
Plain Object (Declarative)
Export API Setting
in plain object directly.
export default {
delay: 1000,
data: {
brand: 'auto'
}
};
Async function (Programmatic)
Export an async function that returns a Promise which resolves / rejects with API Setting
.
For example
async function resolver(ctx: RouterContext) {
let result = await Promise.resolve({
delay: 1000,
data: {
name: 'Peter Pan',
address: '101 Bluestreet, NewYork'
}
});
if (ctx.params.id) {
const id = parseInt(ctx.params.id, 10);
if (id > 5) {
result = await Promise.reject({
status: 404,
data: {
message: 'not found'
}
});
}
}
return result;
}
export default resolver;
API Setting
API Setting
support following features.
Response data, status, delay,
export default {
delay: 1000,
data: {
brand: 'auto'
},
status: 200 // 200 by default
};
Proxy to remote API endpoint
export default {
proxy: true,
host: 'localhost',
protocal: 'http',
port: '3001',
path: '/fake-user-service/:id'
};
Set scenario for related APIs
Declarative
export default {
delay: 1000,
useScenario: [{
api: 'progress',
scenario: ['90-percent', '100-percent']
}]
};
Programmatic
async function resolver(ctx, next, server) {
const result = await Promise.resolve({
data: {
percent: 70
}
});
server.useScenario('progress', '80-percent');
return result;
}
(Optional) Use mqk cli to create API Scenario File
For mqk cli usage see mqk-cli
# install cli tool
npm i -g mqk-cli
# install mock server template
npm i -g mqk-template-mock-server-data@latest
# cd to mock_home/data folder
mqk g
# select mock-server-data
# input the data path
# input default scenario name
# choose whether to include proxy scenario
Validate request headers and data
export default {
data: {
name: 'Peter Pan',
address: '101 Bluestreet, NewYork'
},
validators: [{
rule: {
headers: {
'Content-Type': 'application/json',
'x-csrf-token': /.+/,
'x-extra-info': 'key-abc'
},
body: {
type: 'json',
schema: {
type: 'object',
properties: {
name: {
type: 'string',
},
address: {
'$ref': '/Address'
}
},
required: ['name']
},
refs: [{
'id': '/Address',
'type': 'object',
'properties': {
'street': {
'type': 'string'
},
'city': {
'type': 'string'
}
}
}]
}
},
status: 400
}]
};
Validate http header
rule.headers[key]
can be string
or RegExp
Validate http body
rule.body.type
can be one of json
, form
, text
For json
, following options are available:
rule.body.schema
:JSON schema
rule.body.refs
:JSON schema definitoin
to be referenced in schema
For form
, following options are available:
rule.body.schema
: JSON schema
For text
, following options are available:
rule.body.pattern
:string
orRegExp
Globa configuration file
The global configuration file msconfig.json
can be provided under mock_home
folder. Global configurations are overridden by API specific configurations.
Following is an example configuration file:
{
"delay": 100 // or range {"min": 100, "max": 150}
}
Start The Mock Server
Export your mock_home
path as process.env.MOCK_HOME
or pass it to the constructor of mock server.
For example
import { MockServer } from 'mqk-mock-server';
mockServer = new MockServer({
mockHome: path.resolve(__dirname, '../mock_home')
});
// Listen certain port
mockServer.listen(3000);
Enable HTTPS
import { MockServer } from 'mqk-mock-server';
mockServer = new MockServer({
mockHome: path.resolve(__dirname, '../mock_home'),
https: true,
httpsOptions: {
key: fs.readFileSync('path to key file'), 'utf8'),
cert: fs.readFileSync('path to cert file'), 'utf8')
}
});
// Listen certain port
mockServer.listen(9443);
Stop The Mock Server
mockServer.close();
