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.

Loading the library
Jisly relies on the PSR-4 specification for autoloading classes from file paths.
Definitions
- Each document has a unique identifier called
_rid. - Each collection is physically represented by a file.
- The files are stored in a single working directory. The Jisly class is instantiated with the path to this directory as a parameter.
- Each time you CRUD something, all datas are stored in memory.
- And datas are saved on filesystem.
