@wim.deblauwe/vite-plugin-spring-boot v0.6.0

Vite plugin for Spring Boot backend

Functionality

This vite plugin has 2 main functionlities to make it possible to use Spring Boot with Vite:

• Copy the HTML templates (Thymeleaf or whatever template engine is used) when the Vite Dev Server is running when they change.
• Write a file containing the host and port that the Vite Dev Server is running on. This will allow the Spring Boot application to point to the correct URL for the JavaScript and CSS files so Hot Module Replacement works.

Usage

Add the plugin:

npm i -D @wim.deblauwe/vite-plugin-spring-boot

Update vite.config.js to use the plugin:

import springBoot from '@wim.deblauwe/vite-plugin-spring-boot';

export default defineConfig({
  plugins: [
    springBoot()
  ],
});

This plugin should be used together with the vite-spring-boot library on the backend.

!TIP The easiest way to generate a working setup is to generate the Spring Boot project using ttcli.

Configuration

fullCopyFilePaths

Allows to set what file paths should be copied when anything changes to the files in those file paths. After they are copied, a full page refresh is done.

Example:

export default defineConfig({
    plugins: [
        springBoot({
            fullCopyFilePaths: {
                include: ['**/*.html', '**/*.svg', '**/*.png']
            }
        }),
    ],
});

If the option is not set, the default is used: ['**/*.html', '**/*.svg'].

It is also possible to define exclude to exclude some file paths:

export default defineConfig({
    plugins: [
        springBoot({
            fullCopyFilePaths: {
                include: ['**/*.html', '**/*.svg'],
                exclude: ['**/dontcopyme.svg']
            }
        }),
    ],
});

buildSystem

By default, the plugin assumes that Maven is used, and it will copy files to target/classes.

If you use Gradle and want things to be copied to build/resources, you can configure the plugin like this:

export default defineConfig({
    plugins: [
        springBoot({
            buildSystem: BuildSystem.Gradle
        }),
    ],
});

verbose

When setting verbose to true, the plugin will log more information about what files it copies.

Example:

export default defineConfig({
    plugins: [
        springBoot({
            verbose: true
        }),
    ],
});
