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 stream
Stream
A PSR-7 stream implementation.
Introduction
This package provides an implementation of Psr\Http\Message\StreamInterface for PSR-7. Sometimes you just need a stream but don't want to depend on an entire PSR-7 implementation.
Let's say you are writing a PSR-7 middleware, and it needs to set a new response body.
If you try to write the data with $response->getBody()->write(), there might already be an existing body which is longer than what you want to write. The only way to make that work is to write padding to the end of the string, which is not ideal.
The only way to create a new response body is to instantiate a stream. A good way to do this is to require a factory object as a dependency, and use that to create the stream. The downside is you are adding another setup step that the user will have to configure.
This package lets you provide a default implementation, so your middleware will work without having to setup a stream factory. Since it's a separate package you don't need to pull in an entire PSR-7 implementation just for streams, and you won't end up with dependency conflicts with the user's PSR-7 implementation.
It also includes an interface and adapters for all of the common PSR-7 implementations, so the user doesn't need to set that up manually.
Install
Via Composer
Usage
Factory
The simplest way to use this package is to use the Stream from a scalar, string, resource, or object (if it implements either JsonSerializable or __toString).
Constructor
You can also create a stream directly. You will need to provide a valid resource as the only argument to the constructor.
Allowing Different implementations
To allow the user to use their own stream, you should typehint against the adapters for all of the common implementations, so the user can easily use their own stream.
