Symfony Bundle Template

A collection of useful tools and functions for Symfony projects.

Features

• Apply rate limiters using attributes
• Store Twig templates next to production code
• Use empty strings by default on text-based form fields
• Set various attributes on <form> elements

Installation

If your Symfony installation does not auto-register bundles, add it manually:

Apply rate limiters using attributes

The bundle provides PHP attributes that can be used to apply the Symfony Rate Limiter component.

IMPORTANT: The rate limiter is currently based on the client IP address only. If you are behind a proxy such as Cloudflare you will need to handle accessing the originating client IP address.

First, define the rate limiter that you want to use:

Then add the annotation to the controller you want to protect, specifying the name of the rate limiter in the attribute:

Rate Limiter HTTP Headers

The bundle also provides a listener to add HTTP headers indicating the status of the rate limiter. E.g.

This can be disabled in the bundle configuration if desired:

Store Twig templates next to production code

As discussed on our blog, often it is desirable to store related things together (cohesion). You may want to apply to this your Twig templates.

This bundle provides a compiler pass that will search for multiple Twig tpl directories and add them to the Twig configuration automatically.

This behaviour must be enabled in the configuration by setting the base_dir option:

You can then refer to your Twig templates that live in your production code directories using the following syntax:

Empty string default for text-based form fields

By default Symfony uses null as the default value for text-based form fields. This results in null values being all over the codebase.

An easy way to fix this is to change the default behaviour so text-based fields return an empty string '' instead of null. Then, class properties can be typed string instead of string|null and this can eliminate a lot of null checks in the client code.

This is an opinionated solution, so must be enabled in the bundle configuration:

Set attributes on <form> elements

The bundle provides an easy way to globally set attributes on <form> elements.

These must be explicitly enabled in the configuration.
