Sirius Web

Eclipse Sirius Web is a framework to easily create and deploy studios to the web. We keep the principles which made the success of Eclipse Sirius Desktop and make them available on a modern cloud-based stack.

This repository contains the building blocks from which Sirius Web applications are built. The folder packages contains both the Spring Boot projects from which the corresponding backend is built and the reusable React components used to build the application’s UI. It also contains the Sirius Web sample application.

To test Sirius Web you have two possible options:

1. If you just want to run an already built version of the example application, follow the Quick Start.

2. If you want to build the example application yourself, follow the complete build instructions.

Quick Start

If you want a quick overview of how Sirius Web looks and feels like without building the sample application yourself, you will simply need:

• Java 17

• Docker, or an existing PostgreSQL 12 (or later) installation with a DB user that has admin rights on the database (those are needed by the application to create its schema on first startup).

Then, download the latest pre-built JAR:

1. Go to the packages of the project and look for sirius-web-sample-application.

2. Download the latest jar available

This is a single "fat JAR" named sirius-web-sample-application.jar which contains the complete sample application with all its dependencies.

To actually run the application:

1. Sirius Web uses PostgreSQL for its database. For development or local testing, the easiest way is to start a PostgreSQL instance using Docker.

   docker run -p 5433:5432 --rm --name sirius-web-postgres \
                                -e POSTGRES_USER=dbuser \
                                -e POSTGRES_PASSWORD=dbpwd \
                                -e POSTGRES_DB=sirius-web-db \
                                -d postgres:12

   Warning

   This may take a while the first time you run this as Docker will first pull the PostgreSQL image.

   If you do not have Docker or want to use an existing PostgreSQL installation, adjust the command-line parameters below and make sure the DB user has admin rights on the database; they are needed to automatically create the DB schema.

2. Start the application:

   java -jar sirius-web-sample-application.jar \
             --spring.datasource.url=jdbc:postgresql://localhost:5433/sirius-web-db \
             --spring.datasource.username=dbuser \
             --spring.datasource.password=dbpwd \
             --spring.liquibase.change-log=classpath:db/changelog/sirius-web.db.changelog.xml

3. Point your browser at http://localhost:8080 and enjoy!

   Warning

   The initial version of Sirius Web has some known issues with Firefox. It is recommended to use a Chrome-based browser until these are fixed.

Note	Do not forget to stop the PostgreSQL container once you are done: docker kill sirius-web-postgres. Note that this will remove all the data you have created while testing the application.

Building

Requirements

To build the components in this repository on your own, you will need the following tools installed:

• Git, and a GitHub account

• To build the backend components:

  • Java 17

  • Apache Maven 3.6.3

• To build the frontend components:

  • Recent versions of Node and NPM: in particular, Node >= 18.7.0 is required along with npm >= 8.15.0.

  • TurboRepo (npm install -g turbo)

Warning

Note that there are issues with NPM under Windows Subsystem for Linux (WSL). If you use WSL and encounter error messages like "Maximum call stack size exceeded" when running NPM, switch to plain Windows where this should work.

GitHub Access Token

The backend components of this repository depends on sirius-emf-json, which is published as Maven artifacts in GitHub Packages. To build sirius-components locally, you need a GitHub Access Token so that Maven can download the sirius-emf-json and Flow-Designer artifacts.

1. Create a personal token with a scope of read:package by following the GitHub documentation if you do not have one already.

   Warning

   Once generated, a token cannot be displayed anymore, so make sure to copy it in a secure location.

2. Create or edit $HOME/.m2/settings.xml to tell Maven to use this token when accessing the Sirius EMF JSON repository:

   <?xml version="1.0" encoding="UTF-8"?>
   <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd">
     <servers>
       <server>
         <id>github-sirius-emfjson</id>
         <username>$GITHUB_USERNAME</username>
         <password>$GITHUB_ACCESS_TOKEN</password>
       </server>
       <server>
         <id>github-flow</id>
         <username>$GITHUB_USERNAME</username>
         <password>$GITHUB_ACCESS_TOKEN</password>
       </server>
     </servers>
   </settings>

   Be sure to replace $GITHUB_USERNAME with your GitHub user id, and $GITHUB_ACCESS_TOKEN with the value of your acess token.

   Important

   The id used in your settings.xml must be github-sirius-emfjson and github-flow to match what is used in the POMs.

Build the frontend & backend components and Sirius Web

1. Clone this repository

2. Build the frontend packages:

   npm ci
   npx turbo run build

   Note	In order to run tests, use npx turbo run coverage

3. Install the frontend artifacts as static resource to be served by the backend. From the root directory of the repository:

   mkdir -p packages/sirius-web/backend/sirius-web-frontend/src/main/resources/static
   cp -R packages/sirius-web/frontend/sirius-web/dist/* packages/sirius-web/backend/sirius-web-frontend/src/main/resources/static

4. Build the backend components.

   mvn clean install -f packages/pom.xml

   Tip	If you are behind a proxy, you may get Maven errors about checkstyle.org not being available. In this case you need to explicitly disable CheckStyle from the build: mvn clean install -f releng/org.eclipse.sirius.emfjson.releng/pom.xml -P\!checkstyle

5. You can find in the output artifacts in the various target folders of the backend components and the dist folders of the frontend components. You could publish those to your maven or npm repository to consume them in other applications. We are already publishing those components in the NPM and maven repositories of our Github organization.

   Using these instructions, we can find a Spring Boot "fat JAR" in backend/sirius-web-sample-application/target/sirius-web-sample-application-{YEAR.MONTH.COUNT-SNAPSHOT}.jar. Refer to the instructions in the "Quick Start" section above to launch it.
