Some utilities for JSON pointers described by RFC 6901
Provides some additional stuff i needed but is not included in node-jsonpointer
$ npm install json-pointervar pointer = require('json-pointer');Looks up a JSON pointer in an object.
Array of reference tokens, e.g. returned by api.parse, can be passed as a pointer to .get, .set and .remove methods.
var obj = {
example: {
bla: 'hello'
}
};
pointer.get(obj, '/example/bla');Sets a new value on object at the location described by pointer.
var obj = {};
pointer.set(obj, '/example/bla', 'hello');Removes an attribute of object referenced by pointer.
var obj = {
example: 'hello'
};
pointer.remove(obj, '/example');
// obj -> {}Creates a dictionary object (pointer -> value).
var obj = {
hello: {bla: 'example'}
};
pointer.dict(obj);
// Returns:
// {
// '/hello/bla': 'example'
// }Just like:
each(pointer.dict(obj), iterator);Tests if an object has a value for a JSON pointer.
var obj = {
bla: 'hello'
};
pointer.has(obj, '/bla'); // -> true
pointer.has(obj, '/non/existing'); // -> falseEscapes a reference token.
pointer.escape('hello~bla'); // -> 'hello~0bla'
pointer.escape('hello/bla'); // -> 'hello~1bla'Unescape a reference token.
pointer.unescape('hello~0bla'); // -> 'hello~bla'
pointer.unescape('hello~1bla'); // -> 'hello/bla'Converts a JSON pointer into an array of reference tokens.
pointer.parse('/hello/bla'); // -> ['hello', 'bla']Builds a json pointer from an array of reference tokens.
pointer.compile(['hello', 'bla']); // -> '/hello/bla'Convenience wrapper around the api.
pointer(object) // bind object
pointer(object, pointer) // get
pointer(object, pointer, value) // setThe wrapper supports chainable object oriented style.
var obj = {anything: 'bla'};
var objPointer = pointer(obj);
objPointer.set('/example', 'bla').dict();
