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.

Inserting and updating new nodes
Getting tree nodes
Leaf - returning root node
Children - returning flat collection of children. You can use Eloquent query builder.
Ancestors - returning flat collection of ancestors, first is root, last is current node. You can use Eloquent query builder. Of course there are no guarantees that the structure of the tree would be complete if you do the query with additional where
Descendants - returning flat collection of descendants, first is current node, last is leafs. You can use Eloquent query builder. Of course there are no guarantees that the structure of the tree would be complete if you do the query with additional where
Building tree structure on PHP side - if some nodes will be missing, these branches will not be built
Getting leaf nodes
Map from array
Three new roots, first with descendants
Rendering tree
You can render tree built by the function buildTree
Events
All tree models have additional events:
- updatingParent
- updatedParent
- updatedDescendants
You can use them for example to update additional tables
