How to use multiple schemas in one json file

readme.md

Nx project json example

To make json schema intellisense work in vscode with Nx configurations use $ref in order to use $schema

{
-  "$schema": "../../node_modules/nx/schemas/project-schema.json",
+  "$ref": "file:../../node_modules/nx/schemas/project-schema.json",
  // ...
}

Also you can add custom schemas with more refs

nx-project-schema-vscode-intellisense.json

{
  "$ref": "file:../../node_modules/nx/schemas/project-schema.json",
  "sourceRoot": "apps/checkout",
