## WAT
Offers a (i think production ready) REST service to convert files like PDF, docx,xlx .. odt .. you get it.. to other formats like pdf, png, doc, pdt, html.
This project is basically an extended version of [jodconverter-samples-rest](https://github.com/jodconverter/jodconverter-samples/tree/main/samples/spring-boot-rest)
You can use this project as it is using docker with `ghcr.io/eugenmayer/kontextwork-converter` or build it here yourself.
## Usage
```bash
docker run --memory 512m --name converter-prod --rm -p 8080:8080 ghcr.io/eugenmayer/kontextwork-converter:production
```
Now convert a `docx` to `html`
```bash
cd officeconverter
curl -F file=@src/test/resources/testfiles/withpictures.docx "localhost:14080/conversion?format=html" -o /tmp/test.html
curl -F file=@src/test/resources/testfiles/template.dotx "localhost:14080/conversion?format=html" -o /tmp/test.html
```
### REST endpoints
Check the controller to understand the different endpoints
- `/conversion?format=html` as multipart with `file` as the file to convert and `format` for the target format
### Configuration
You can configure the docker images by mounting `/etc/app/application.yml` and put whatever you like into them.
For example if you like to have 2 LibreOffice instances, you would put into the file
```yaml
# amount of libreOffice instances to start - one for each given port. So this means 2
jodconverter:
local:
port-numbers:
- 2002
- 2003
# change the tmp folder
working-dir: /tmp
# change upload sizes
spring:
servlet:
multipart:
max-file-size: 5MB
max-request-size: 5MB
# change the server port (where the REST app is listenting)
server:
portL: 8090
```
### Adding addition document formats
You can edit the [src/resources/document-formats.json](src/resources/document-formats.json) and add new custom formats.
The original can be found at (https://github.com/jodconverter/jodconverter/blob/master/jodconverter-core/src/main/resources/document-formats.json)[jodconverter-core].
We already added support for `dotx/xltx` for example.
### Build
local java build, when you have all the build tools present + libreoffice locally installed
./gradlew build
# you find the artifact in /tmp/gradle-officeconverter/builds/libs/officeconverter-*.jar
# the jar file is a full tomcat bundled app, so just start it like that
java -jar /tmp/gradle-officeconverter/build/libs/officeconverter-*.jar
or better use the docker image with everything included, no dev tools/LO needed locally
```bash
# this builds the source a
make build
make start-prod
```
You can now connect to the 5001 remote debugger port, just use the existing IntelliJ task if you like
### Tests
You can run the tests locally (you will need libreoffice installed)
```bash
./gradlew itTests
```
Or run the test in the docker-container
```bash
make test
```
## Development
You can either use the IDE task or the local gradle
./gradlew -Pdev bootRun
Or even better, use the development container. You will not need any LibreOffice/Gradle installed locally
make start-src # basically just docker-compose up
This fires up a docker container, mounts your source. To auto-rebuild and auto-restart he app very quick do this
make watch
# or just run ./watch.sh localy
### Debugging
Of course, you can just start using your IDE and debug that, but if you want to debug inside the docker container
make start
And now connect(attach) to localhost 5001 for debugging `ghcr.io/eugenmayer/kontextwork-converter:development` has a default remote
debugging port enabled on 5001
## Release
CI based on tags
### Upgrade
To upgrade libreoffice or the jodconverter runtime
-
- see available releases under https://github.com/jodconverter/docker-image-jodconverter-runtime
- create pr and adjust `.github/docker-pr.yml` and `.github/docker-pr.yml` `RUNTIME_VERSION` to match your version
- Update the RUNTIME_VERSION in the `makefile`
- run `make test` and ensure the test run inside the docker container (against the pre-build libre office and the JDK version)
- merge PR if tests run successfully
## Internals
- state of the art springboot 3.0 application exposing a classic rest service to convert office document
- using [jodconverter-spring-boot-starter](https://github.com/jodconverter/jodconverter/tree/master/jodconverter-spring-boot-starter) for wiring jodconverter-local services
- build on/for Java 17 for better Docker support
## Warranty
Absolutely none, use it at your own risk and without any guarantees.
