Simple [htmx][htmx] project using spring boot with thymeleaf as backend.
Generated by [spring initializr][initializr].
See [HELP.md][help] for further details.
## Requirements
- maven 3.9
- java 17
- htmx 2.0 (webjar)
- spring 3.2 with webflux
## How to build
```bash
./mvnw clean package
```
## How to test
```bash
./mvnw test
```
## How to run
```bash
./mvnw spring-boot:run
```
Or:
```bash
java -jar target/sample-htmx-spring-0.0.1-SNAPSHOT.jar
```
## Noteworthy
- Used [functional endpoints][webflux] instead of traditional [web mvc][webmvc]
to make this sample more similar to the [other][javalin] [ones][koa].
- `RouterFunctions` demands specific routes to be declared first, this is why
the configuration function looks slightly different from its kotlin and node
counterparts.
- Spring webflux is built on top of [project reactor][reactive] and demands a
functional thinking way, therefore the difference in controller code.
- [Spring repositories][repository] are a formidable abstraction.
- Liquibase defaults in spring configuration renders a broken project because it
does [assume a root changelog][changelog-master] but it does not assume the
[changelog format][changelog-format].
- [Thymeleaf is a little picky][thymeleaf-include] regarding the templates
"includes".
- Added additional java build tooling, so we can compare maven, gradle and
[bld][bld]. It's a nice comparison and all three tools can produce a valid
spring boot jar.
## Benchmark results
