Node.js Task App Quickstart

To get started right away without having to build an app from scratch, explore with the Ditto ready-to-use demo task app.

Prerequisites

Before you can install Ditto, you must have the following:

Ditto access credentials
Node.js active long-term support (LTS) version 18.x or 20.x
Linux, macOS version 11 (or later), or Windows version 10 (or later)
Git
Integrated developer environment (IDE)

To get your access credentials, complete the Onboarding.
You can use any IDE you prefer; however, for optimal compatibility with the platform, Ditto recommends using Visual Studio Code.

Installing the Demo Task App

To install Ditto in your environment, install and set up Ditto, and authenticate your client identity with the Big Peer:

Clone the getditto > template-app-nodejs-todo repository from GitHub:

git clone https://github.com/getditto/template-app-nodejs-todo/

Install the required dependencies:

npm install

Open the project in your IDE, and then open the index.ts file. For example, if using Visual Studio Code:

code .

In line 14 of the index.ts file, replace 'YOUR_APP_ID' and 'YOUR_TOKEN' with your app ID and playground token. (Ditto Basics > Getting Your Access Credentials)

// replace YOUR_APP_ID and YOUR_TOKEN with p
ditto = new Ditto({ type: 'onlinePlayground', appID: 'YOUR_APP_ID', token: 'YOUR_TOKEN' })

Build the demo task app:

npm run build

Interact with the demo task app and simulate real-time peer-to-peer replication by running the demo task app in two or more separate terminals (one for each virtual peer):

node index.js

Using the commands that automatically appear in each of your terminals, add, remove, and modify documents as desired.

If you want to observe your changes sync with the cloud-optional deployment, the Big Peer, open the data browser in the Ditto portal.
