FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:

If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
To use Composer is sometimes complicated. Especially for beginners.
Composer needs much resources. Sometimes they are not available on a simple webspace.
If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Please rate this library. Is it a good library?

Maintenance Mode Bundle — Put a Symfony site into maintenance mode (HTTP 503) with configurable exclusions, a Twig admin panel, scheduled windows, append-only history, and pluggable storage / access gates. Tested on Symfony 7.4, 8.0, and 8.1 · PHP 8.2+ (Symfony 8.x requires PHP 8.4+).

This bundle is FrankenPHP worker mode friendly.

Features

503 listener — Configurable-priority kernel.request interceptor (default after router), HTML or JSON, dynamic Retry-After, Cache-Control: no-store.
Exclusions — Exact paths, prefixes, route names, globs, #regex# / ~regex~, IPs/CIDR, #[ExcludeFromMaintenance], soft bypass token.
Admin panel — Enable / disable / schedule / clear schedule / history under a configurable prefix (default /_maintenance).
CLI — nowo:maintenance-mode:enable (--until, --message, --actor), nowo:maintenance-mode:disable, nowo:maintenance-mode:status, nowo:maintenance-mode:hash-password.
Events & Twig — Domain events on state changes; nowo_maintenance_is_enabled() / nowo_maintenance_state().
Password gate — Optional password_hash (bcrypt / argon2id); replaceable via MaintenanceAccessGateInterface.
Pluggable storage — Filesystem JSON/JSONL by default; swap for Doctrine or anything else via DI.

Installation

With Symfony Flex, the recipe registers the bundle and adds config. Without Flex, see docs/INSTALLATION.md.

Requirements

PHP >=8.2 (<8.6); Symfony 8.0 and 8.1 require PHP 8.4+
Symfony 7.4, 8.0, or 8.1 (^7.4 || ^8.0)
Twig for the maintenance page and panel templates

Configuration

Usage

Open /_maintenance to toggle maintenance. Visitors hit the public page with HTTP 503; excluded routes and the panel keep working. In dev, preview the configured page at /_maintenance_preview (like /_error/503). Demo gallery: /examples.
