Starting from ReSharper 2022.2, active development of productivity features for JavaScript, TypeScript, JSON, CSS, and Protobuf is suspended, and these features are disabled by default. To enable them, select the corresponding checkboxes on the Environment | Products & Features page of ReSharper options Alt+R, O: JavaScript and TypeScript, CSS Language, and Protobuf.
ReSharper allows you to mark some JSON properties as specific value types (for example regular expression, file path) so that ReSharper could apply specific validation and provide specific completion suggestions for matching properties in JSON files.
You can add a value helper for specific properties on the Code Editing | JSON | JSON Value Helpers page of ReSharper options . The matching is based on a filename mask and/or schema, and a path to the JSON property (such as /compilerOptions/rootDir).
Your JSON value helpers preferences are saved using the mechanism of layer-based settings. Among other things, this mechanism allows you to maintain different preferences for different solutions as well as to keep these preferences under a VCS and automatically share them with your team members.
To improve performance, ReSharper also automatically detects and starts ignoring large web files that have no references and were probably added to the solution by mistake.
If any of such files are detected, you will see a notification where you can stop ignoring any of those files if you need them. You can also find all automatically ignored files on the Code Editing | Third-Party Code page of ReSharper options .
To stop auto-detection and ignoring large unused web files, clear the Search for web files that can affect performance and exclude them from indexing checkbox on the Code Editing | Third-Party Code page of ReSharper options .
