Using TLS and HTTP/2 in development

Introduction

This page is for using TLS and HTTP/2 in development (mainly for testing purposes). For production configuration, please read the security section in the production documentation .

TLS is the protocol used when having an https:// URL, and it is required in order to use HTTP/2 on modern browsers.

It is useful to use those protocols when testing an application, mainly for performance reasons.

Using TLS and HTTP/2 with Spring Boot

JHipster has a specific configuration for configuring both TLS and HTTP/2 (see the common application properties documentation), and in order to make things even simpler:

• JHipster generates a self-signed certificate at application generation
• A specific tls profile is provided (see the profiles documentation)

In order to run JHipster with the provided self-signed certificate, with TLS and HTTP/2 enabled, you just need to use this tls profile:

• with Maven: ./mvnw -Pdev,tls
• with Gradle: ./gradlew -Ptls

The application will be available on https://localhost:8080/.

As the certificate is self-signed, your browser will issue a warning, and you will need to ignore it (or import it) in order to access the application.

Using TLS and HTTP/2 with Angular or React

Instead of using npm start in order to run the front-end (with Webpack and BrowserSync), just run npm run start-tls, and it will connect to the back-end running on https://localhost:8080/.

Everything should then work the same as without TLS and HTTP/2.
