🔎 What Is Redocusaurus?

Learn what Redocusaurus does and why it’s perfect for Spring Boot.

Moreover, these pages let users explore your API’s endpoints, parameters, and responses easily.

Therefore, Redocusaurus is great for Spring Boot teams who want simple, up-to-date docs without writing frontend code.

Then, start your Spring Boot app.

After that, open your browser and go to: http://localhost:8080/v3/api-docs

Next, you will see your API spec in JSON format.

Finally, convert the JSON to YAML using Swagger Editor: paste the JSON, click Convert to YAML, and save the file as openapi.yaml.

🌍 Deploy Your Docs Anywhere with Ease

From build to production in just one command.

Once your Redocusaurus app is ready, deploying it is simple.
You just need to build the project using npm run build.
This command generates a static React app inside the build folder.
Because it’s a pure frontend, you can host it anywhere.
For example, Netlify, GitHub Pages, Vercel, or even an S3 bucket.

Just upload the contents of the build folder.
That’s it!
Your API documentation is now live, fast, and accessible.

Since it’s static, it’s also SEO-friendly and easy to cache.
You can deploy updates anytime by rebuilding and pushing the new files.
