What are the editors for JSON with code completion and code validation according to the specified JSON schema?

Question

IDE

I am looking for a JSON file editor, where you can specify a JSON Schema (a schema file or a link to it) for the file being edited, and after that it will be possible to validate and auto-complete the code.
For example, you need to edit the composer.json file. All composer.json configuration files have the same structure, corresponding to this JSON schema . Accordingly, when editing such a file, it would be useful to be able to:
a) see a list of hints, i.e. attributes allowed in a given location of the file, as well as valid attribute values, and use code completion when typing;
b) check your file against the selected schema to make sure it does not contain errors in syntax and semantics
In the absence of all this, editing such a file is like writing code in any programming language in a regular Notepad:
a) you have to keep all the rules of syntax and semantics in your head or constantly check with the reference documentation for the format of the edited JSON file;
b) the lack of auto-completion significantly slows down the work and increases the percentage of errors
In the list of tools that can do this, I found only Visual Studio, but such a monster is not suitable for me for such a small task.
