About this extension
Monaco Editor works well with large files, which is not the case with devtools.jsonview. This extension integrates a stripped-down build of monaco-editor-0.52.2 when viewing a document with a content type .../json. It has auto-support for light and dark themes from the browser, as well as a list of languages (en, ru, de, es, fr, it, ja, ko, zh-cn, zh-tw).
