With them you will be able to create simple and flexible solutions to problems that are not natively supported. You can define extensions in or combine them or even create multiple lightweight.


Client instances with different extensions. When you're ready you can share your extension with the community as a snippet or package it and publish it to. This photo editing servies article will show you what's possible with extensions and hopefully inspire you to create and share your own extensions. We believe client-side extensions will open up many new possibilities when working with them. Yet just because a problem can be solved with extensions doesn't mean it can never be solved with first-class functionality. One of our goals is to experiment and explore solutions with our community and then integrate them natively. Using Client Side Extensions To use client side extensions you need to first enable the preview feature in the schema file and then you can call the method on the client instance. This returns a new extended client instance without modifying the original instance. You can chain calls to use multiple extensions and create.



Separate instances with different extensions. The components of an extension can contain four different types of components. Model components allow you to add new methods to the model. This is a convenient way to add new actions next to default methods such as etc. You can use it as a repository for common query methods to encapsulate the business logic of your model or to perform any operation you might perform using static methods on a class. This demonstrates a way to implement internationalization in the data access layer of an application. implement any kind of custom transformation or field serialization or deserialization on the query results. View the sample code example Obfuscation Fields This example is a special case of the previous Transform Fields example. It uses extensions to hide sensitive fields on the model.
