FCEditor: Modeling of Function Choreographies (Serverless Workflows) and building them in AFCL (Abstract Function Choreography Language)

FCEditor is a graphical user interface for building, editing, and exporting function choreographies in AFCL. It offers the FC developers several benefits:

• Builds complex workflows including base functions and compound functions (if, switch, parallel, parallelFor)
• Supports many features of AFCL (constraints, properties, data-flow, control-flow)
• No 'real programming skills' needed for modeling
• Optimization of created workflows

The FCEDitor is accessible at http://fceditor.dps.uibk.ac.at:8180/.

Getting started

Requirements (Development)

• Java (JDK >= 12)
• Maven
• Node v12

Install dependencies

1. Add AFCL API to local maven repo: mvn install:install-file -Dfile=./src/main/resources/afclAPI.jar -DgroupId=com.dps.afcl -DartifactId=afcl-api -Dversion=1.0 -Dpackaging=jar
2. Install dependencies: mvn install

If using an IDE, reimport - e.g if using IntelliJ:
right click on Project -> Maven -> Reimport

Build and run

1. mvn compile
2. mvn package
3. sh target/bin/webapp

If using an IDE, create a build configuration - e.g if using IntelliJ:
Run -> Edit Configurations -> Add a configuration and select launch.Main as main class.

Frontend

1. cd into src/main/webapp
2. npm ci (recommended when package-lock.json present) or npm i
3. npm run dev or npm run build
