express-parameters v1.0.4

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.

````javascript
    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(', '));
    }
````
