express-parameters

Install

npm install express-parameters

Usage

1. Call express-parameters in your controller or route.

   var ExpressParameters = require('express-parameters');

2. Specify required fields in a array, in this case we assume that we are using the Validator for any auth route.

   var required = ['username', 'password'];

3. In ExpressJS we have the req.body object, which contain our parameters sent from the client, and we pass req.body object to the validator together with our array with our required fields.

   ExpressParameters.request(req.body, null, required);

4. Using Scenario.

       if (ExpressParameters.passed()) {
           // If Validation Passed
           var parameters = ExpressParameters.get(); // We get the parameters
           // Do something
           res.send('Successfully loggedin');
       } else {
           // If Validation Failed return error message
           res.send('Missing parameters: ' + ExpressParameters.failed.join(', '));
       }
