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?

Informations about the package lazydatasource

Sandstorm.LazyDataSource

Inspector Data Sources in Neos are usually eager, this means the UI sends a single request to the backend to load all options, and then doing the filtering client-side.

This package implements additional Inspector Editors, behaving like the standard SelectBoxEditor with data sources, but delegates filtering and searching to the server-side.

This greatly improves Neos UI performance for data sources with big collections (100s of elements).

Getting started

  1. Default composer installation via:

  2. for a single select:

    In your NodeTypes.yaml, activate the custom editor by using Sandstorm.LazyDataSource/Inspector/Editors/DataSourceSelectEditor instead of Neos.Neos/Inspector/Editors/SelectBoxEditor. **All configuration options of the data source-based select apply as usual.

    Additionally, we support the following additional editorOptions:

    • dataSourceMakeNodeIndependent: if set to TRUE, the currently selected node is NOT sent to the data source on the backend, increasing the cache lifetime on the client (e.g. the system can re-use elements from other nodes)

    Example:

  3. for a multi select:

    In your NodeTypes.yaml, activate the custom editor by using Sandstorm.LazyDataSource/Inspector/Editors/DataSourceSelectEditor instead of Neos.Neos/Inspector/Editors/SelectBoxEditor. **All configuration options of the data source-based select apply as usual.

    Additionally, we support the following additional editorOptions:

    • dataSourceMakeNodeIndependent: if set to TRUE, the currently selected node is NOT sent to the data source on the backend, increasing the cache lifetime on the client (e.g. the system can re-use elements from other nodes)

    Example:

    Do not forget to set the property type to array<string>.

  4. In your DataSource implementation on the server, use the LazyDataSourceTrait and implement the two methods getDataForIdentifiers() and searchData(). Do not implement getData() (as this is provided by the trait).

    • getDataForIdentifiers() is called during the initial call, when the client-side needs to resolve entries for certain identifiers.
    • searchData() is called when the user has entered a search term, and needs to perform the searching.

    The return value for both methods needs to be the same as for normal data sources.

    Example:

Development

This project works with yarn. The build process given by the neos developers is not very configurable, only the target dir for the buildprocess is adjustable by package.json.

If you don't have yarn already installed:
