simple-form

$ version 1.0.0

Form processor for filter and validation form data. This base on form. I develop this module because the idea of this package is very good, but the current module didn't work.

Installation

Install simple-form then run the following.

$ npm install simple-form --save-dev

Example

Processing an example form:

var form = require('simple-form');
 
var elements = {
    name: [
        form.filter(form.Filter.trim)
    ]
};
 
form
    .create(elements)
    .process({'name': ' tester ', 'active': '1'}, function(error, data) {
        console.log('error:', error);
        console.log('data:', data);
    });

The result:

error: null
data: { name: 'tester' }

Extend your validator

You can define your own validator:

var form = require('simple-form');
 
form.extend('isNotEmpty', function(str) {
    return (str.length > 0) ? true : false;
});
 
var elements = {
    name: [
        form.filter(form.Filter.toString),
        form.filter(form.Filter.trim),
        form.validator(form.Validator.isNotEmpty, 'Bad Name'),
    ],
    email: [
        form.filter(form.Filter.toString),
        form.filter(form.Filter.trim),
        form.validator(form.Validator.isNotEmpty, 'Bad Email'),
    ]
};
 
form
    .create(elements)
    .process({
        active : '1',
        name   : ' tester ',
        email  : '  '
    }, function(error, data) {
        console.log('error:', error);
        console.log('data:', data);
    });

The result:

error: { email: [ 'Bad Email' ] }
data: { name: 'tester', email: '' }

Your own validator

You can use your own validator:

var form = require('simple-form');
 
function customNameValidator(data, name, callback) {
    setTimeout(function(){
        callback('So bad', data);
    }, 500);
}
 
var elements = {
    name: [
        form.filter(form.Filter.toString),
        form.filter(form.Filter.trim),
        customNameValidator
    ]
};
 
form
    .create(elements)
    .process({
        active : '1',
        name   : ' tester '
    }, function(error, data) {
        console.log('error:', error);
        console.log('data:', data);
    });

The result:

error: { name: [ 'So bad' ] }
data: { name: 'tester' }
