We provide a [project-list](/frontend) LitElement which can be used as a frontend for this service. + +Build +-------- +Execute the following command on your shell: +```shell +gradle clean build +``` +Make sure to use **Java 17** and **Gradle 7.2**. + +Service Properties +-------- +The project service uses a group agent to store envelopes containing the lists of available projects. +This allows, to access these envelopes using different service agents. +As an example, when updating your service, you do not loose access to the projects, but a new service agent can be added to the group agent instead (which will grant access to the envelopes). + +Depending on whether you are starting the service for the first time (and do not have a service group agent yet) or whether you are starting an updated version of the service, different properties (or environment variables) have to be set. + +When you are starting the service for the first time, you need to set the docker environment variable "NEW_GROUP_AGENT". Then on the first start of the service, a new group agent is generated for the service. In case you want to update your service at a later point and still want to have access to your projects, please note down the agent id of your service, the password for the service agent and also the id of the service group agent. +You can find the id of the service group agent in the etc/startup/group.xml file. + +When you want to restart your service after an update, you need to remove the "NEW_GROUP_AGENT" environment variable. +Instead, you now need to set the variables "SERVICE_GROUP_ID", "OLD_SERVICE_AGENT_ID" and "OLD_SERVICE_AGENT_PW" accordingly. +When using the service, your new service agent will be automatically added to the existing group by using the old service agent and it's password. + +Besides that, you need to configure the systems that the project service should handle projects for. +Therefore, you may use the "SYSTEMS" environment variable. +It should be set to a JSON object which could look as follows, if you are using two systems: +``` +{ + "SBF": { + "visibilityOfProjects": "own" + }, + "CAE": { + "visibilityOfProjects": "all", + "eventListenerService": "i5.las2peer.services.modelPersistenceService.ModelPersistenceService@0.1" + } +} +``` +In this example, we are supporting two systems, namely the "SBF" and "CAE". +In the CAE it is possible to view all projects, even the ones where a user is no member of. +The SBF only allows to read those projects, where the user is a member of. +Besides that, the ModelPersistenceService is called in the CAE, if specific events (such as project-creation) occur. For more information, see the section on the event listener service. + +GitHub Projects Extension (Optional) +------------------------------------ +It is possible to enable the GitHub projects extension for a system. +Then, for every las2peer project in the system, a corresponding GitHub project will be created and can be used for project management. +To enable the extension for a system, edit the "SYSTEMS" environment variable. +In the example from above, enabling it for the system named SBF would work as follows: +``` +... +"SBF": { + ... + "gitHubProjectsEnabled": true, + "gitHubOrganization": , + "gitHubPersonalAccessToken": +} +... +``` +The GitHub projects will be added within the given GitHub organization. +Therefore, a personal access token is required, that allows to use the GitHub API to create new GitHub projects in the organization and to add members to it. + +Event Listener Service +-------- +The project service provides the possibility to set another las2peer service as an event listener service. +On specific events (such as project-creation), the project service calls the configured event listener service via RMI. +In order to work properly, the event listener service needs to implement the following public methods for the specific events: + +| Event | Method | Description | +|-------------------|-------------------------------------------|----| +| Project creation | _onProjectCreated(JSONObject projectJSON) | Event gets fired whenever a new project gets created. The JSONObject will then be a JSON representation of the created project. | +| Project deletion | _onProjectDeleted(JSONObject projectJSON) | Event gets fired whenever a project gets deleted. The JSONObject will then be a JSON representation of the deleted project. | + +RMI Methods +-------- +Besides the event listener service, other services in general have the possibility to communicate with the project service via RMI. +Therefore, the project service provides the following methods: + +| Method | Description | +|------------------------------------------------|-------------| +| boolean hasAccessToProject(String system, String projectName) | This method may be used to verify if a user is allowed to write-access a project. Returns true, if the calling agent has access to project. Returns false otherwise (or if project with given name does not exist). | +| boolean changeMetadataRMI(String system, String body) | RMI wrapper for "/{system}/changeMetadata" REST method. Returns true if metadata could be updated successfully. | +| JSONObject getProjectMetadataRMI(String system, String projectName) | This method may be used to access the metadata of a project via RMI. Returns the metadata as a JSONObject or null if access to project was not granted. | + +Start +-------- + +First of all make sure that you have a running instance of the [Contact Service](https://github.com/rwth-acis/las2peer-contact-service) and the [User Information Service](https://github.com/rwth-acis/las2peer-user-information-service). + +To start the Project Service, use one of the available start scripts: + +Windows: + +```shell +bin/start_network.bat +``` + +Unix/Mac: +```shell +bin/start_network.sh +``` + +After successful start, Project Service is available under + +[http://localhost:8080/projects/](http://localhost:8080/projects/) + +Setup with docker +------------------ +To run the service for development purposes using docker, please refer to the [wiki](https://github.com/rwth-acis/las2peer-project-service/wiki/Local-development-instance-setup). diff --git a/bin/.gitignore b/bin/.gitignore new file mode 100644 index 0000000..896c87b --- /dev/null +++ b/bin/.gitignore @@ -0,0 +1,2 @@ +start_network.bat +start_network.sh diff --git a/bin/start_GroupAgentGenerator.bat b/bin/start_GroupAgentGenerator.bat new file mode 100644 index 0000000..cb8ce7c --- /dev/null +++ b/bin/start_GroupAgentGenerator.bat @@ -0,0 +1,14 @@ +@echo off + +cd %~dp0 +cd .. +set BASE=%CD% +set CLASSPATH="%BASE%/lib/*;" + +if "%~1"=="" ( + echo Syntax error! + echo. + echo Usage: start_GroupAgentGenerator filePathServiceAgent1 path2 +) else ( + java -cp %CLASSPATH% i5.las2peer.tools.GroupAgentGenerator %1 %2 +) diff --git a/bin/start_GroupAgentGenerator.sh b/bin/start_GroupAgentGenerator.sh new file mode 100644 index 0000000..6cff361 --- /dev/null +++ b/bin/start_GroupAgentGenerator.sh @@ -0,0 +1 @@ +java -cp "lib/*" i5.las2peer.tools.GroupAgentGenerator "$@" \ No newline at end of file diff --git a/bin/start_ServiceAgentGenerator.bat b/bin/start_ServiceAgentGenerator.bat new file mode 100644 index 0000000..914f27c --- /dev/null +++ b/bin/start_ServiceAgentGenerator.bat @@ -0,0 +1,14 @@ +@echo off + +cd %~dp0 +cd .. +set BASE=%CD% +set CLASSPATH="%BASE%/lib/*;" + +if "%~2"=="" ( + echo Syntax error! + echo. + echo Usage: start_ServiceAgentGenerator service.canonical.class.name service.password +) else ( + java -cp %CLASSPATH% i5.las2peer.tools.ServiceAgentGenerator %1 %2 +) diff --git a/bin/start_ServiceAgentGenerator.sh b/bin/start_ServiceAgentGenerator.sh new file mode 100644 index 0000000..4dd8481 --- /dev/null +++ b/bin/start_ServiceAgentGenerator.sh @@ -0,0 +1,6 @@ +#!/bin/bash + +# this scripts generates a xml file for the specified ServiceClass with the desired ServicePass +# pls run the script form the root folder of your deployment, e. g. ./bin/start_ServiceAgentGenerator.sh + +java -cp "lib/*" i5.las2peer.tools.ServiceAgentGenerator "$@" diff --git a/bin/start_UserAgentGenerator.bat b/bin/start_UserAgentGenerator.bat new file mode 100644 index 0000000..4cf7360 --- /dev/null +++ b/bin/start_UserAgentGenerator.bat @@ -0,0 +1,14 @@ +@echo off + +cd %~dp0 +cd .. +set BASE=%CD% +set CLASSPATH="%BASE%/lib/*" + +if "%~2"=="" ( + echo Syntax error! + echo. + echo Usage: start_UserAgentGenerator user.name user.password user.mail +) else ( + java -cp %CLASSPATH% i5.las2peer.tools.UserAgentGenerator %2 %1 %3 +) \ No newline at end of file diff --git a/bin/start_UserAgentGenerator.sh b/bin/start_UserAgentGenerator.sh new file mode 100644 index 0000000..2356a67 --- /dev/null +++ b/bin/start_UserAgentGenerator.sh @@ -0,0 +1,6 @@ +#!/bin/bash + +# this scripts generates an user agent as xml file in order to upload it via the startup folder +# pls run the script form the root folder of your deployment, e. g. ./bin/start_UserAgentGenerator.sh + +java -cp "lib/*" i5.las2peer.tools.UserAgentGenerator "$@" diff --git a/docker-entrypoint.sh b/docker-entrypoint.sh new file mode 100644 index 0000000..7b68afd --- /dev/null +++ b/docker-entrypoint.sh @@ -0,0 +1,118 @@ +#!/usr/bin/env bash + +set -e + +# print all comands to console if DEBUG is set +if [[ ! -z "${DEBUG}" ]]; then + set -x +fi + +# set some helpful variables +export SERVICE_PROPERTY_FILE='etc/i5.las2peer.services.projectService.ProjectService.properties' +export WEB_CONNECTOR_PROPERTY_FILE='etc/i5.las2peer.connectors.webConnector.WebConnector.properties' +export SERVICE_VERSION=$(awk -F "=" '/service.version/ {print $2}' gradle.properties) +export SERVICE_NAME=$(awk -F "=" '/service.name/ {print $2}' gradle.properties) +export SERVICE_CLASS=$(awk -F "=" '/service.class/ {print $2}' gradle.properties) +export SERVICE=${SERVICE_NAME}.${SERVICE_CLASS}@${SERVICE_VERSION} + +function set_in_service_config { + sed -i "s?${1}[[:blank:]]*=.*?${1}=${2}?g" ${SERVICE_PROPERTY_FILE} +} + +# check mandatory variables +[[ -z "${SYSTEMS}" ]] && \ + echo "Mandatory variable SYSTEMS is not set.

+[![npmjs](https://img.shields.io/npm/v/@rwth-acis/las2peer-project-service-frontend?color=success)](https://www.npmjs.com/package/@rwth-acis/las2peer-project-service-frontend) + +The project-list is a LitElement for listing projects given by the las2peer-project-service and for creating new projects. + +Basic Usage +------------------- + +To use the project-list LitElement in your project, just install it from [npmjs](https://www.npmjs.com/package/@rwth-acis/las2peer-project-service-frontend): + +``` +npm i @rwth-acis/las2peer-project-service-frontend +``` + +Then you can use the project-list element as follows: + +```html + +``` + +Here, SYSTEM_NAME needs to match with a system that is configured in the project-service. +For the configuration of systems, see the [main README](https://github.com/rwth-acis/las2peer-project-service). +Set PROJECT_SERVICE_URL and CONTACT_SERVICE_URL to the address of the webconnector, where the respective service can be found. + +The project-list element uses [Yjs](https://github.com/yjs/yjs) to share the metadata of the currently selected/opened project with other project members that have selected the same project. +This ensures, that every project member always gets the latest changes to the metadata. +To configure the used y-websockets-server instance, use the attributes `yjsAddress` and `yjsResourcePath`. +Please note: To keep the metadata of projects secured, the project-list uses an extended version of y-websockets-server and y-websockets-client. +This extension allows to use Yjs rooms that only project members can access. +The extensions can be found in the rwth-acis forks [rwth-acis/y-websockets-server#project-service](https://github.com/rwth-acis/y-websockets-server/tree/project-service) and [rwth-acis/y-websockets-client#v8](https://github.com/rwth-acis/y-websockets-client/tree/v8). + + +You may also use the `disableAllProjects` attribute to disable the tab where all available projects are listed. + +Events +------------- + +**Events fired by the project-list element:** + +`projects-loaded`: + +The project-list element fires this event whenever the projects are reloaded from the project-service. +The event details contain a list of all projects that the current user can access. +Depending on how the visibility of all projects is configured in the project-service, also projects where the current user is no member of will be part of the list. + +`project-selected`: + +Whenever the user clicks on one of the projects in the list, this event will be fired. +It contains detailed information on the selected project and its metadata. + +`metadata-changed`: + +If the metadata of the currently selected/opened project got changed, this event will be fired. +It contains the updated project metadata. +If you display the metadata in the UI and want to keep it up-to-date, then you can use this event. + +**Events that the project-list element listens for:** + +`metadata-change-request`: + +The project-list element listens to the event "metadata-change-request". +It can be used to update the metadata of the currently selected project. +If you send the event and set the event details to the updated metadata, the project-list element will send it to the project-service and after that the "metadata-changed" event will be fired. + +`metadata-reload-request`: + +If you updated the metadata without using the "metadata-change-request" event, as an example by using the RMI interface of the project-service, then you should use this event to inform the project-list element about it. +When receiving the event, the project-list will fetch the metadata from the project-service again and will also send a "metadata-changed" event. + +`projects-reload-request`: + +This event can be used to reload the list of projects. +It might be used after the user has logged in. + +Extension: SyncMeta Online User List +------------------------------------------- + +If your projects are using [SyncMeta](https://github.com/rwth-acis/syncmeta), you can use the online user list extension. +It allows to display the users that are currently online in a project / SyncMeta room. +To use the online user list, the project-list element needs to know which project is using which Yjs room(s) for modelling. +You can use the method "setOnlineUserListYjsRooms", that the project-list element provides, for this. +As a parameter you use a map that maps project names to a list of Yjs room names (which are used for modelling inside the project). + +Development +----------------------------- +For testing the element during development, run `npm i` and `npm run serve`. +There is a demo available that can be used during development. diff --git a/frontend/callbacks/openidconnect-icons.js b/frontend/callbacks/openidconnect-icons.js new file mode 100644 index 0000000..67524d4 --- /dev/null +++
