Readme
This is an implementation of RFC-6901 JSON Pointer. JSON Pointer is designed for referring to data values within a JSON document. It's designed to be URL friendly so it can be used as a URL fragment that points to a specific part of the JSON document.
Includes support for node.js JavaScript (CommonJS and ES Modules), TypeScript, and browsers.
npm install @hyperjump/json-pointer
const JsonPointer = require("@hyperjump/json-pointer");
const value = {
"foo": {
"bar": 42
}
};
// Construct pointers
const fooPointer = JsonPointer.append(JsonPointer.nil, "foo"); // "/foo"
const fooBarPointer = JsonPointer.append(fooPointer, "bar"); // "/foo/bar"
// Get a value from a pointer
const getFooBar = JsonPointer.get(fooBarPointer);
getFooBar(value); // 42
// Set a value from a pointer
// New value is returned without modifying the original
const setFooBar = JsonPointer.set(fooBarPointer);
setFooBar(value, 33); // { "foo": { "bar": 33 } }
// Assign a value from a pointer
// The original value is changed and no value is returned
const assignFooBar = JsonPointer.assign(fooBarPointer);
assignFooBar(value, 33); // { "foo": { "bar": 33 } }
// Unset a value from a pointer
// New value is returned without modifying the original
const unsetFooBar = JsonPointer.unset(fooBarPointer);
setFooBar(value); // { "foo": {} }
// Delete a value from a pointer
// The original value is changed and no value is returned
const deleteFooBar = JsonPointer.remove(fooBarPointer);
deleteFooBar(value); // { "foo": {} }
