Install via Meteorite
$: mrt add regulate.jsWhat it does
Regulate allows you to write your validation requirements once and use them on the client and server.
Features
- Error message insertions into the DOM (optional)
- Validates
input type='file'fields (file sizes and types) - Customizable rules
- i18n support
What it doesn't do
- Regulate does not submit form data, it merely validates it and reports back with a result.
- Regulate supports validations for fields that should match (like for passwords), but doesn't support fields whose validation requirements depend on the value of other fields.
Basic Usage
The form:
<form id="registerUser">
<input type='text' name='username'/>
<p id='username-error'></p>
<input type='password' name='password1'/>
<p id='password1-error'></p>
<input type='password' name='password2'/>
<p id='password2-error'></p>
<input type='text' name='email'/>
<p id='email-error'></p>
<input type='file' name='profileImage'/>
<p id='profileImage-error'></p>
<input type='submit'/>
</form>The validation requirements can be shared by client and server by placing them in lib/validations.js or anywhere else outside of the client and server folders.
Regulate('registerUser', [
{
name: 'username',
min_length: 3,
max_length: 5,
display_as: 'Username',
display_error: '#username-error'
}, {
name: 'password1',
min_length: 5,
max_length: 12,
display_as: 'Password',
display_error: '#password1-error'
}, {
name: 'password2',
match_field: 'password1',
display_as: 'Confirmation',
display_error: '#password2-error'
}, {
name: 'email',
email: true,
display_as: 'Email',
display_error: '#email-error'
}, {
name: 'profileImage',
max_size: 1024 * 10, //10kb
accepted_files: 'jpeg|png',
display_as: 'Profile image',
display_error: '#profileImage-error'
}
]);On the client side, register an onSubmit callback to get validation results:
Meteor.startup(function () {
Regulate.registerUser.onSubmit(function (error, data) {
if (error) {
console.log('Validation failed. These are the errors: ', error);
} else {
console.log('Validation passed. This is the data: ', data);
// Send the data over to the server via an exposed Meteor method:
Meteor.call('registerUser', data);
}
});
});On the server side, expose an RPC method that will validate the form data:
Meteor.methods({
registerUser: function (data) {
Regulate.registerUser.validate(data, function (error, data) {
if (error) {
console.log('Server side validation failed.');
} else {
console.log('Server side validation passed!');
// Save data to database or whatever...
}
});
}
