parse-wrapper

Introduction

This is a wrapper for Parse to simplifying codes for data retrieving and modifying from Parse.

Please be aware that this plugin is only meant to implement a minimal subset of features of Parse, that are sufficient to implement a simple application with Parse backend. Basically, only data retrieving and updating are supported. If you need more features of Parse, please use the official SDK instead.

Parse server is now supported.

Syntax

Initializing

Loading module

To load the plugin:

var parse = require('parse-wrapper');

.initialize(keyObject)

To initialize Parse with your own keys:

var keys = {
    appKey: 'fakeAppKey',
    jsKey: 'fakeJSKey',
    username: 'username',
    password: 'password'
};
parse.initialize(keys); // return a promise

.login(loginInfo)

To login:

parse.login({username: 'username', password: 'password'})
    .then(token => {
        parse.getAll('Test', token)
            .then(console.log);
    });

This function returns a promise with the session token.

Retrieving data

.getAll(class, token)

To get all objects belonging to class Test:

parse.getAll('Test', token)
    .then(console.log)
    .catch(console.error);

The token parameter is optional.

.getSome(class, condition, token)

To get all the objects matching some conditions (e.g. has attribute testing equal to true) in class Test:

parse.getSome('Test', {testing: true})
    .then(console.log)
    .catch(console.error);

The objects will be returned as an array.

.getOne(class, condition, token)

This is similar to .getSome(), but only the first match will be returned.

parse.getOne('Test', {testing: true}, token)
    .then(console.log)
    .catch(console.error);

.getOneByID(class, id, token)

To get the object with id of 1234 from class Test:

parse.getOneByID('Test', '1234', token)
    .then(console.log)
    .catch(console.error);

Deleting data

.deleteOneByID(class, id, token)

To delete the object with id of 1234 from class Test:

parse.deleteOneByID('Test', '1234', token)
    .then(() => {
        console.log('success!');
    })
    .catch(console.error);

Updating data

.updateOneByID(class, id, newObject, token)

To replace the object with id of 1234 from class Test with object newObject:

parse.updateOneByID('Test', '1234', newObject, token)
    .then(() => {
        console.log('success!');
    })
    .catch(console.error);

Counting Objects

.countSome(class, condition, token)

This is similar to .getSome(), but only the number of match(es) found will be returned.

parse.countSome('Test', {testing: true}, token)
    .then((count) => {
        console.log('count:', count);
    })
    .catch(console.error);

.countAll(class, token)

parse.countAll('Test', token)
    .then((count) => {
        console.log('count:', count);
    })
    .catch(console.error);

Saving objects

.save(class, obj, token)

To save a new object obj into class 'Test':

parse.save('Test', obj, token)
    .then(() => {
        console.log('successfully deleted!');
    })
    .catch(console.error);
