Deployment

Docker

Docker is the easiest way to get started with CommaFeed.

Docker images are built automatically and are available at https://hub.docker.com/r/athou/commafeed

Cloud hosting

PikaPods offers 1-click cloud hosting solutions starting at $1/month with a free $5 welcome credit and officially supports CommaFeed. PikaPods shares 20% of the revenue back to CommaFeed.

Download precompiled package

mkdir commafeed && cd commafeed
wget https://github.com/Athou/commafeed/releases/latest/download/commafeed.jar
wget https://github.com/Athou/commafeed/releases/latest/download/config.yml.example -O config.yml
java -Djava.net.preferIPv4Stack=true -jar commafeed.jar server config.yml

The server will listen on http://localhost:8082. The default user is admin and the default password is admin.

Build from sources

git clone https://github.com/Athou/commafeed.git
cd commafeed
./mvnw clean package
cp commafeed-server/config.yml.example config.yml
java -Djava.net.preferIPv4Stack=true -jar commafeed-server/target/commafeed.jar server config.yml

The server will listen on http://localhost:8082. The default user is admin and the default password is admin.

Memory management

The Java Virtual Machine (JVM) is rather greedy by default and will not release unused memory to the operating system. This is because acquiring memory from the operating system is a relatively expensive operation. However, this can be problematic on systems with limited memory.

Hard limit

The JVM can be configured to use a maximum amount of memory with the -Xmx parameter. For example, to limit the JVM to 256MB of memory, use -Xmx256m.

Dynamic sizing

The JVM can be configured to release unused memory to the operating system with the following parameters:

-Xms20m -XX:+UseG1GC -XX:-ShrinkHeapInSteps -XX:G1PeriodicGCInterval=10000 -XX:-G1PeriodicGCInvokesConcurrent -XX:MinHeapFreeRatio=5 -XX:MaxHeapFreeRatio=10

This is how the Docker image is configured. See here and here for more information.

Translation

Files for internationalization are located here.

To add a new language:

• add the new locale to the locales array in:
  • commafeed-client/.linguirc
  • commafeed-client/src/i18n.ts
• run npm run i18n:extract
• add translations to the newly created commafeed-client/src/locales/[locale]/messages.po file

The name of the locale should be the two-letters ISO-639-1 language code.

Local development

Backend

• Open commafeed-server in your preferred Java IDE.
  • CommaFeed uses Lombok, you need the Lombok plugin for your IDE.
• Start CommaFeedApplication.java in debug mode with server config.dev.yml as arguments

Frontend

• Open commafeed-client in your preferred JavaScript IDE.
• run npm install
• run npm run dev

The frontend server is now running at http://localhost:8082 and is proxying REST requests to the backend running on port 8083
