About The Project

Wordle has taken over the world (or at least the first 5-15 minutes of my mornings). Inspired by 3Blue1Brown's video about information theory, I believe we can learn to make better guesses by studying how the Wordle Solver "thinks" (similar to the way Chess players study games played against computers). Using the Wordle Solver can tell us:

• What are the best starting words?
• What word should I pick to narrow down my options given the words guessed so far?
• What are common prefixes and suffixes that fit word validation constraints?

If you're interested in the math behind the project, check out my high-level design document.

Built With

• Java Spring Boot: Backend framework to develop the algorithm logic
• React.js: Frontend framework to develop the client website
• AWS Elastic Beanstalk: Cloud service for managing web environments and deploying the application

Getting Started with Development

To get a local copy up and running, follow these steps.

Prerequisites

Install these prerequisites and clone the repository.

• Java 8
• Node
• Yarn
• Maven

git clone git@github.com:valarao/wordle-solver.git

Backend Testing

Now, you can test the backend with code coverage reports.

1. Build locally

   mvn clean jacoco:prepare-agent install && mvn jacoco:report

2. Analyze coverage report at /target/site/jacoco/index.html

Preview Backend Changes with Client

You can also build the project, run the executable .jar file, and view the bundled client.

1. Build locally

   mvn clean install && java -jar target/wordle-solver.jar

2. Preview client on localhost:5000

Quick-Preview Client without Building Server

Alternatively, you can quick-preview the frontend client separately.

1. Build locally

   mvn clean install && java -jar target/wordle-solver.jar

2. Navigate directly into client folder

   cd src/main/ui

3. Install node modules

   yarn install

4. Start development client

   yarn start

5. Preview client on localhost:3000 (frontend changes automatically detected)
