Supported JS libraries

Supported JavaScript libraries

To assist in streamlining the process of creating mock server definitions, we have included a selection of useful third-party JavaScript libraries within the mock server runtime. These libraries have been pre-installed and are automatically injected into the JavaScript context, eliminating the need for you to manually include them using the require() function. Simply begin utilizing them in your code.

The list of supported libraries are:

  • lo-dash v4.17.21 (general utility)
  • momentjs v2.30.1 (time and dates)
  • faker 5.5.3 (data generator)
  • ajv 6.10.0 (JSON schema validation)
  • validator 13.12.0 (validation helper)

If you have a suggestion for a library that is not currently available, contact us and suggest it.

 
mock.define("/example", "GET", function (req, res) { 
  // faker lib
  var myState = faker.lorem.text()
  faker.lorem.slug() // 'dolores-illo-est'
  faker.lorem.slug(5) // 'delectus-totam-iusto-itaque-placeat'
  faker.lorem.slug({ min: 1, max: 3 }) // 'illo-ratione'
 
   // ldash lib
  console.log(_.eq("Geeks", "Geeks" )); 
 
  // use moment lib
  moment().format('MMMM Do YYYY, h:mm:ss a'); // August 26th 2024, 5:35:05 pm
  moment().format('dddd');                    // Monday
  moment().format("MMM Do YY");               // Aug 26th 24
  moment().format('YYYY [escaped] YYYY');     // 2024 escaped 2024
  moment().format();   
  moment("20111031", "YYYYMMDD").fromNow(); // 13 years ago
  moment("20120620", "YYYYMMDD").fromNow(); // 12 years ago
  moment().startOf('day').fromNow();        // 18 hours ago
  moment().endOf('day').fromNow();          // in 6 hours
  moment().startOf('hour').fromNow(); 
  
  // Ajv lib
  const ajv = new Ajv()
  const schema = {
    type: "object",
    properties: {
      foo: {type: "integer"},
      bar: {type: "string"}
    },
    required: ["foo"],
    additionalProperties: false
  }
 
  const data = {foo: 1, bar: "abc"}
  const valid = ajv.validate(schema, data)
  if (!valid) console.log("invalid")
 
  // validator js
  var result = validator.isEmail('foo@bar.com');
  console.log(result ? "isEmail":"not email");
  
  return res.json(myState || {})
 });
