Opal questions

[Ricardo Cavalheiro]

Hello,

I was having some doubts regarding Opal.
I am trying to set up a development environment with Opal but I am currently struggling.
I figured out the Java sdk version to use, but  I have some questions:
How should i run opal in a development environment?
Can I run separately the frontend and backend?
Can I use Docker to help me with building problems? If so, can you share with me a template Dockerfile?

Thank you for your attention,
Ricardo Cavalheiro

Hi,

The dev version of opal is in the "master" branch. FYI we are currently making major changes due to the migration to java 21.

 

* To build the application, just run "make all" (javac 21 required). 

* To run the application, you'll need a opal home folder, see "make prepare" (you can use the obiba-home repo to get some default datasets), then run "make debug".

* To run the frontend separately, modify CORS policy by editing the opal_home/conf/opal-config.properties file and adding the line "cors.allowed=*". Then go to the folder opal-ui and run "npm run dev". If you are developing your own frontend app, connect to the rest web services located at http://localhost:8080/ws

You can also use a Docker environment, see the "dev" branch of docker-opal, there is a Makefile, and default docker compose.
