FAQ
Example:
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 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.
Informations about the package feature-flag
Feature Flag
This is a simple library to enable/disable features based on a set of rules.
Installation
Configuration
Choose the driver you want to use. Currently, the library supports the following drivers:
- InMemory - stores data in memory. This driver is used by default.
- phpredis extension
InMemory
Configure the driver in the dependency injection container configuration file:
di.php
Or with params.php:
Configuring the driver with
params.phpis only available for theInMemoryDriver.
Redis
Configure the driver in the dependency injection container configuration file:
di.php
The driver uses a hash table functions to store and retrieve data. Read more about the hash table functions here.
Choose a driver
After you have chosen a driver, you need to configure the dependency injection container:
di.php
`
Usage
Pull \Xepozz\FeatureFlag\FlagStorageInterface from the dependency injection container and use it:
isActive(string|int|BackedEnum $flag): bool
setFlag(string|int|BackedEnum $flag, bool $active): void
Be careful, in case of using not the
InMemoryDriver, the flag will be stored permanently.In case of using the
InMemoryDriver, the flag will be stored only for the current request. So you can switch the flag depending on the conditions in your code. For instance, you can enable the feature only for trusted IP addresses.
getAll(): array
Returns all flags as an associative array array<string, bool>.
The only InMemoryDriver supports returning BackendEnum as a key, because it does not need to serialize the key.
The key is the flag name, the value is the flag state.
Testing
Redis
Redis driver requires phpredis extension and a running Redis server.
You can use the following command to start a Redis server in a Docker container:
Or use docker-compose:
