What is json-everything?

The primary philosophy behind json-everything is to ensure that common JSON functionality has good support in the System.Text.Json space.

The first step to that is checking whether there exist other projects that support a given function.

If so, that effort likely won't be duplicated here. A bit farther down you'll find a list of other projects that are doing some cool things with JSON.

Otherwise, it's open to consideration for this project.

What's in the box?

There are actually multiple boxes. Each piece of functionality has been broken out into its own library, so you can pick and choose the one(s) that you need.

All libraries are built to .Net Standard 2.0 and .Net 8.

DISCLAIMER My library, JsonSchema.Net, is not related to or associated with the website, except that they are both excellent JSON Schema tools.

Deprecated packages

These packages have also been a part of this suite but are no longer supported.

System.Text.Json support by other projects

If you don't find what you're looking for here, please try one of these excellent projects:

If you use JSON to do something that is not covered by a library in this suite or one of the above projects, feel free to create a feature issue.

If you maintain or know of another project that extends System.Text.Json to do cool things, I'd like to list it here, so please create a general issue to let me know about it.
