Remult

Remult is a lightweight web application framework for Full-Stack TypeScript.

Define Entity classes

import { Entity, EntityBase, Field } from 'remult';

@Entity('Products', {
    allowApiCrud: true
})
export class Product extends EntityBase {
  @Field()
  name: string = '';

  @Field()
  unitPrice: number = 0;
}

Find and manipulate data in front end code...

static increasePriceOfTofu(priceIncrease: number) {
  const product = await remult.repo(Product).findFirst(p => p.name.isEqualTo('Tofu'));

  product.unitPrice += priceIncrease;
  await product.save();
}

...exactly the same way as in back end code

@BackendMethod({ allowed: Allow.authenticated })
static increasePriceOfTofu(priceIncrease: number, remult?: Remult) {
  const product = await remult.repo(Product).findFirst(p => p.name.isEqualTo('Tofu'));

  product.unitPrice += priceIncrease;
  await product.save();
}

Secure the API with Fine-grained Authorization

@Entity<Article>('Articles', {
    allowApiRead: true,
    allowApiInsert: remult => remult.authenticated(),
    allowApiUpdate: (remult, article) => article.author.id == remult.user.id
})
export class Article extends EntityBase {
    @Field({ allowApiUpdate: false })
    slug: string;
    
    @Field({ allowApiUpdate: false })
    author: Profile;

    @Field()
    content: string;
}

Remult handles the REST:

• Secured back-end API endpoints for Entities and back-end methods
• CRUD API requests (front end) / database commands (back end)
• Object-relational mapping
• Validations
• Caching
• Authorization

Installation

npm i remult

API Setup using Express

import * as express from 'express';
import { remultExpress } from 'remult/remult-express';
import 'entities';

let app = express();
app.use(remultExpress());
app.listen(3002, () => console.log("Server started"));
