Monaco JSON

JSON language plugin for the Monaco Editor. It provides the following features when editing JSON files:

• Code completion, based on JSON schemas or by looking at similar objects in the same file
• Hovers, based on JSON schemas
• Validation: Syntax errors and schema validation
• Formatting
• Document Symbols
• Syntax highlighting

Schemas can be provided by configuration. See here for the API that the JSON plugin offers to configure the JSON language support.

Internally the JSON plugin uses the vscode-json-languageservice node module, providing the implementation of the functionally listed above. The same module is also used in Visual Studio Code to power the JSON editing experience.

• Important: both monaco repositories must have the same parent folder.
• in folder monaco-json run npm install and run npm run watch
• in folder monaco-editor run npm install and run npm run simpleserver
• open http://localhost:8080/monaco-editor/test/?monaco-json=dev

• change to the same favorite source folder (/src/) that already contains monaco-json and monaco-editor
• git clone https://github.com/Microsoft/vscode (this will create $/src/vscode/)
