Read JSON data from a file written with writeJsonToFile.


(Promise<object>): A promise that fulfills with either null (in case the file does not contain valid JSON, or if the file does not exist) or an object with the contents of the file.


import lampix from '@lampix/core';
.then(console.log); // { answerToLife: 42 }


localStorage API is also enabled. You can use it instead of this method. localStorage, by design, is a blocking I/O operation (synchronous). Use writeJsonToFile and readJsonFromFile if you want to use non-blocking (asynchronous) I/O operations.

readJsonFromFile (like localStorage), is application specific. This means one application cannot retrieve the saved data of another application.
