However, schemas can also be defined in a file in the VS Code workspace, as well as the VS Code settings files. Servers like JSON Schema Store provide schemas for most of the common JSON-based configuration files. The JSON support shipped with VS Code supports all draft versions from Draft 4 to JSON Schema Draft 2020-12.

JSON schemas describe the shape of the JSON file, as well as value sets, default values, and descriptions. To understand the structure of JSON files, we use JSON schemas. You can also directly modify the files.associations setting to associate file names or file name patterns to jsonc. Select the mode indicator to change the mode and to configure how file extensions are associated to modes. The current editor mode is indicated in the editor's Status Bar. When in the JSON with Comments mode, you can use single line ( //) as well as block comments ( /* */) as used in JavaScript. This mode is used for the VS Code configuration files such as settings.json, tasks.json, or launch.json.

In addition to the default JSON mode following the JSON specification, VS Code also has a JSON with Comments (jsonc) mode. Folding regions are available for all object and array elements. You can fold regions of source code using the folding icons on the gutter between line numbers and line start. You can format your JSON document using ⇧⌥F (Windows Shift+Alt+F, Linux Ctrl+Shift+I) or Format Document from the context menu. When you hover over properties and values for JSON data with or without schema, we will provide additional context. JSON files can get large and we support quick navigation to properties using the Go to Symbol command ( ⇧⌘O (Windows, Linux Ctrl+Shift+O)).

We also offer IntelliSense for specific value sets such as package and project dependencies in package.json, project.json, and bower.json. We also perform structural and value verification based on an associated JSON schema giving you red squiggles. You can also manually see suggestions with the Trigger Suggestions command ( ⌃Space (Windows, Linux Ctrl+Space)). json, VS Code provides features to make it simpler to write or modify the file's content.įor properties and values, both for JSON data with or without a schema, we offer up suggestions as you type with IntelliSense. We also use it extensively in Visual Studio Code for our configuration files.

JSON is a data format that is common in configuration files like package.json or project.json. Configure IntelliSense for cross-compilingĮdit Editing JSON with Visual Studio Code.
