• validate a string
• validate an enum type
• validate an array
• ExpressJS example

This library was intended to validate user req.body in your node/express projects for example.

See the code version example here

const validation = makeValidation((types) => {});

makeValidation method returns a callback, the callback has all the valid types of validations available.

const validation = makeValidation((types) => {
  return {
    payload: {
      firstName: 'john',
      lastname: 'doe',
    },
  };
});

payload is the actual data you want to verify

const validation = makeValidation(types => {
  return {
    payload: {
      firstName: 'john',
      lastname: 'doe'
    }
    checks: {
      firstName: { type: types.string },
      lastname: { type: types.string },
    }
  }
});

checks will check the data in the payload if they are of the right type.

For every check type there are some options available.

• options.empty (default false) will check if the string is allowed to be empty '' or not.

• options.unique (default false) will check if the array is unique or not
• options.stringOnly (default false) will check if the all the values in array are strings or not
• options.empty (default true) will check if the array is empty allowed or not

• options.enum (default {}, required: yes) It can be of 2 types string and object.

checks: {
  userType1: { type: types.enum, options: { enum: 'admin user' } },
  userType2: {
    type: types.enum,
    options: {
      enum: { 0: 'admin', 1: 'user' },
    },
  },
},

• If options.enum a string the enum is seperated by space.
• If options.enum an object the enum are the values in the objects.
