Sync To Do

Progressively Enhanced React To Do List. HTML–first, Node, Express, PostgreSQL.


Have a look at the synchronous and asynchronous endpoints in action. Run the live demo at our Heroku Dino.

What you need

Install the grunt-cli package if you haven't before. This should be done as a global install:

npm install -g grunt-cli

Make sure you have grunt installed by testing:

grunt --version

To interact with the application you'll need to be running PostgreSQL for the database. Install Postgres if you haven't already. Mac users can install Postgres via brew.

Create a synctodo database.


Next import our example data. Data will be imported into a tasks table.

psql synctodo < _build/db/synctodo.sql

Getting Started

First, clone a copy of this git repo by running:

git clone -b grunt

Then cd into the synctodo folder and install the Node dependencies:

cd synctodo
npm install

You should now be able to build the files and run the Node server!

grunt build
npm run serve

The server will automatically restart when changes are made. To watch the Sass source files for changes and automatically rebuild the source files, run the grunt command:

grunt #alias for grunt watch

By default this project runs on port 1187. To run it on a different port use the PORT environmental variable:

PORT=8081 npm run serve #visit http://localhost:8081 in your browser

To use a database with a different name use the PGDATABASE environmental variable:

PGDATABASE=anotherdb npm run serve


  • Add, Complete, Archive, and Delete Tasks
  • Progressive Enhancement (.no-js) support
  • Isomorphic HTML layer doubles as a data model for Redux
  • Isomorphic server uses the same promises for asynchronous and synchronous requests
  • React Routing
  • React and Redux used on both server and client side
  • REST API prefetches and fetches data to keep UI fresh
  • Loads dependencies from CDN with local fallback
  • Feature detection to only load scripts if they'll work (IE9+)

A simple PostgreSQL database schema is used to store our tasks. See server.js for the queries that interact with the database to add, complete, archive, unarchive, and delete tasks.

CREATE TABLE "tasks" (
  title varchar(255) NOT NULL DEFAULT '',
  completed smallint NOT NULL DEFAULT '0',
  archived smallint NOT NULL DEFAULT '0'
