GrapeJelly

I was jelly of ruby-grape's grape-entity gem so here we have a JavaScript serializer framework inspired by grape-entity. It is not intended to be a complete implementation of grape-entity.

Install

1npm install @lbennett/grape-jelly
2# OR
3yarn add @lbennett/grape-jelly

Usage

Define entities by extending the Entity class. You must implement a define method that defines the entity using Entity.prototype.expose.

1import { Entity } from '@lbennett/grape-jelly';
2
3class UserEntity extends Entity {
4  define() {
5    this.expose('username', { as: 'not_username' });
6    this.expose('password', user => user.notPassword);
7  }
8}

You can use Entity.prototype.represent to serialize your object.

1import UserEntity from './UserEntity';
2
3const data = {
4    username: 'foo',
5    password: 'bar',
6    notPassword: 'raboof',
7    otherValue: 'not included',
8};
9
10const entity = new UserEntity();
11const serializedData = entity.represent(data);
12
13console.log(serializedData);
14
15// { not_username: 'foo', password: 'raboof' }
