How to Create a Healthy Lifestyle App Using Spring Boot and Redis

It’s not easy training your body out of bad habits. Whether that’s having a poor diet or slacking off at the gym, or ignoring it altogether, much of it comes down to mindset. Personal development is a trend that’s galvanized many of us to shake off bad habits and transform ourselves into new and better people. 

But invoking serious change begins with measuring your progress to determine whether the two steps you’ve made have taken you closer or further away from your goal. Without any forms of measurement, the journey can become rudderless. 

Helping to keep you on the right track is ABettaMe – a healthy lifestyle app that allows you to measure different variables to see how far you’ve progressed with your goals. Through this application, you can experiment with different diets and exercises to see what impact they have on your health. 

Redis was leveraged to streamline data transmission between components and to create an application that was highly responsive to the user’s commands. Let’s take a look at how this application was put together. 

But before we go any further, we’d like to point out that you can discover a variety of innovative applications just like ABettaMe on the Redis Launchpad

So make sure to check them out after this post!

1. What will you build?

You’ll build an application that will help users make important lifestyle changes by allowing them to measure progress in granular detail. Below we’ll show you how to bring this application to life by walking you through each stage of the implementation process, along with the components you’ll need. 

Ready to get started?

Ok, let’s dive straight in. 

2. What will you need?

This project is composed of five different components. In each section, we’ll highlight all of the different technologies and tools required to build the application. 

ABettaMe Dashboard

  • Typescript: used as a superset of the Javascript language that has a single open-source compiler.
  • React: used as a Javascript library for building user interfaces. 

ABettaMe Gateway

  • Javascript: the text-based programming language used both on the client-side and server-side
  • Spring Cloud Gateway: gives you a library for building an API gateway on top of Spring WebFlux. 

ABettaMe Experiments

  • Javascript: the text-based programming language used both on the client-side and server-side.
  • Spring Boot: used as an open source Java-based framework to create a microservice. 
  • RedisJSON: used to store, update, and fetch JSON values from Redis keys.
  • Redis Pub/Sub: used for event messaging and can provide messages to any number of subscribers on a channel.

ABettaMe Recommendation

  • C#: used as a general purpose, multi-paradigm programming language. 
  • .NET 5: used as a unified platform to create any type of .Net app with a single base library. 
  • RedisJSON: used to store, update, and fetch JSON values from Redis keys.
  • Redis Pub/Sub: used for event messaging and can provide messages to any number of subscribers on a channel.

ABettaMe Contract

Google Protocol Buffers: used as Google’s language-neutral, platform-neutral extensible mechanism for serializing structured data.

3. Architecture

  • The frontend first notifies the backend for any new metrics which are saved in the RedisJSON store. 
  • New metrics are published in the Redis Pub/Sub module. 
  • A recommendations microservice analyzes the data and carries out significance testing. 
  • The user can then identify if the changes are having an impact on their desired metrics. 

4. Getting started

Step 1: Clone the repository 

git clone: https://github.com/redis-developer/abetta-ux

Step 2. Inspecting the services

Open the docker-compose file that specifies the various services required to build this application:

version: '3.8'
services:
  abetta-xp:
    container_name: abetta-xp
    image: abettame/abetta-xp:local
  abetta-gateway:
    container_name: abetta-gateway
    image: abettame/abetta-gateway:local
    ports:
      - 8080:8080
  abetta-rec:
    container_name: abetta-rec
    image: abettame/abetta-rec:local
  abetta-portal:
    container_name: abetta-portal
    image: abettame/abetta-portal:local
    ports:
      - 3000:3000

Step 3: Start the docker

Use the following command to start the docker:

docker-compose up -d
docker-compose ps
NAME                COMMAND                  SERVICE             STATUS              PORTS
abetta-gateway      "sh -c 'java -Dserve…"   abetta-gateway      running             0.0.0.0:8080->8080/tcp
abetta-portal       "docker-entrypoint.s…"   abetta-portal       running             0.0.0.0:3000->3000/tcp
abetta-rec          "/bin/sh -c 'ASPNETC…"   abetta-rec          running
abetta-xp           "sh -c 'java -Dserve…"   abetta-xp           running

5. How the application works

Let’s deep dive into each of the modules  that build this application.

ABettaMe Dashboard:

UI interface to manage existing experiments, or record new ones.

Performing an experiment

This is one of the most important aspects of the application, where you’re able to test new things and see the impact of what different changes are having on your life. First, click on the ‘Create new experiment’ icon on the dashboard.

You’ll then need to fill out some information about your experiment in the given fields, including:

  • Experiment name
  • Metric: Determine the variable you’ll be measuring. For example, if you’re trying to track weight loss, then you’d select ‘weight.’
  • Control: Provide details about the strategy that you’ll be following to achieve your goals. 

Treatment: Insert information on what tactics you’ll follow to execute your strategy.

Logging in results

On the dashboard, you’ll see an overview of your experiment. Click on ‘Add metric’ to log your latest results. You’ll then be taken to a new page where you’ll have a number of fields to fill in, including date, metric, and value (see below).

Monitoring your progress

On the left-hand side of the screen, you’ll see the different experiments you have listed. Once you’ve clicked on the experiment you want to view, you’ll see a graph that will give you a visual representation of your progress. 

The application will also list any milestones achieved that are representative of how well you’re progressing towards your goals (see below).

Conclusion: measuring your progress at speed with Redis

Measuring progress is a fundamental aspect of personal development. It allows you to discover whether you’ve made two steps forward, two steps back, or at a complete standstill. But for any measurement system to be effective, it needs to be fast, accurate, and easily accessible. 

Redis’ advanced data processing capabilities guaranteed a highly-responsive application where users were able to interact with it in real time without any lags, freezes, or delays. New metrics were saved on the RedisJSON store and were published through the RedisPubSub module with hyper-efficiency, providing users with a seamless application experience.
