Resident Services Developers Guide

Overview

Resident Services are the self-services which are used by the residents themselves via a portal. Resident Portal is a web based UI application that provides residents of a country the services related to their Unique Identification Number (UIN).

The documentation here will guide you through the pre-requisites required for the developer' setup.

Software setup

Below are a list of tools required in Resident Services:

  1. JDK 11

  2. Any IDE (like Eclipse, IntelliJ IDEA)

  3. Apache Maven (zip folder)

  4. pgAdmin

  5. Postman

  6. Git

  7. Notepad++ (optional)

  8. lombok.jar (file)

  9. settings.xml (document)

Follow the steps below to set up Resident Services on your local system:

  1. Download lombok.jar and settings.xml from here.

  2. Install Apache Maven.

  3. Copy the settings.xml to ".m2" folder C:\Users\<username>\.m2.

  4. Install Eclipse.

  5. Open the lombok.jar file and wait for some time until it completes the scan for Eclipse IDE and then click Install/Update. Specify the eclipse installation location if required by clicking the ‘Specify location…’ button. Then, click Install/Update button to proceed.

  6. Check the Eclipse installation folder C:\Users\userName\eclipse\jee-2021-12\eclipse to see if the lombok.jar is added. By doing this, you will not have to add the dependency of lombok in your pom.xml file separately as it is auto-configured by Eclipse.

  7. Configure the JDK (Standard VM) with your Eclipse by traversing through Preferences → Java → Installed JREs.

Code setup

For the code setup, clone the repository and follow the guidelines mentioned in the Code Contributions.

Importing and building of a project

  1. Open the project folder where pom.xml is present.

  2. Open command prompt from the same folder.

  3. Run the command mvn clean install -Dgpg.skip=true -DskipTests=true to build the project and wait for the build to complete successfully.

  4. After building of a project, open Eclipse and select Import Projects → Maven → Existing Maven Projects → Next → Browse to project directory → Finish.

  5. After successful importing of project, update the project by right-click on Project → Maven → Update Project.

Environment setup

  1. For the environment setup, you need an external JAR that is available here with different versions. Download below mentioned JARs with appropriate latest/appropriate versions. You will need to input appropriate artifact id and version and other inputs.

    a. icu4j.jar

    b. kernel-auth-adapter.jar

    c. kernel-ref-idobjectvalidator.jar

    d. kernel-transliteration-icu4j.jar

    For e.g.: You can download kernel-auth-adapter.jar and add to project Libraries → Classpath → Add External JARs → Select Downloaded JAR → Add → Apply and Close).

  2. Clone mosip-config repository.

    a. As Resident Services is using two properties files- resident-default.properties and application-default.properties. But for local running of the application, you need to provide additional/overriding properties such as secrets, passwords and properties passed by the environment which can be added in new files application-dev-default.properties (common properties for all modules) and resident-dev-default.properties (Resident service specific properties).

    b. You will have to create both the property files according to your environment and put them in mosip-config folder (cloned). The same files are available below for reference.

    These two files are loaded by application by specifying the application names in the Application VM arguments like- Dspring.cloud.config.name=application,resident,application-dev, resident-dev (also detailed in later section).

  3. To run the server, two files are required- kernel-config-server.jar and config-server-start.bat.

  4. Put both the files in the same folder and point the property- Dspring.cloud.config.server.native.search-locations to mosip-config folder in config-server-start.bat file and also check the version of kernel-config-server.jar towards the end of the command.

    Example:

    java -jar -Dspring.profiles.active=native  -
Dspring.cloud.config.server.native.search-
locations=file:C:\Users\myDell\mosipProject\mosip-config -
Dspring.cloud.config.server.accept-empty=true  -
Dspring.cloud.config.server.git.force-pull=false -
Dspring.cloud.config.server.git.cloneOnStart=false -
Dspring.cloud.config.server.git.refreshRate=0 kernel-config-server-1.2.0-20201016.134941-57.jar

  • As mentioned earlier, you will have to create property files according to your environment like resident-env-default and application-env-default (here env represents environment name). Both files will contain different configurations such as resident-env-default will have config properties (e.g., secrets, passcodes, etc) used for resident-services module only and application-env-default is used for environment specific changes and can be used for other modules as well.

  • In this example, currently, these two files are created for dev environment and hence the files have suffix of -dev. If you want to run it for a different environment such as qa, create these two files with -qa suffix and then you will also need to provide the appropriate VM argument for that referring to qa environment.

For instance,

  • Add mosip.resident.client.secret=*********** property to be able to use a decrypted passcode and run it in your local machine.

  • If you check the URLs present in application-default file, they are set to module specific URLs, but you need to use internal/external environment URLs to access the APIs by using application-dev-default file.

  • In application-dev-default file, assign environment domain URL to mosipbox.public.url and change all other URLs with ${mosipbox.public.url}.

  • It results in mosipbox.public.url=internal/externalAPI (e.g., mosipbox.public.url=https://api-internal.dev.mosip.net) and it will connect with the Development environment.

  1. Run the server by opening the config-server-start.bat file.

Configurations to be done in Eclipse

  1. Open Eclipse and run the project for one time as Java application, so that it will create a Java application which you can see in debug configurations and then change its name. (e.g.: project name with environment - "Resident-dev").

  2. Open the Arguments tab and specify Application VM arguments: For example, for dev environment:

    -Dspring.profiles.active=default -
 Dspring.cloud.config.uri=http://localhost:51000/config -
 Dspring.cloud.config.label=master -Dsubdomain=dev -
 Dspring.cloud.config.name=application,resident,application-dev,resident-dev --illegal-access=permit.

    Save this run configuration as ‘Resident-dev’ .

    For qa environment, you can create Resident-qa run configuration with VM argument as below.

    Example:

    -Dspring.profiles.active=default -
Dspring.cloud.config.uri=http://localhost:51000/config -
Dspring.cloud.config.label=master -Dsubdomain=qa -
Dspring.cloud.config.name=application,resident,application-qa,resident-qa --illegal-access=permit

  3. Click Apply and then debug it (starts running). In the console, you can see a message like Started ResidentBootApplication in 34.078 seconds (JVM running for 38.361).

Resident services API

  • For API documentation, refer here.

  • The APIs can be tested with the help of Postman or Swagger-UI.

  • Postman is an API platform for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration so you can create better APIs—faster. It is widely used tool for API testing. Below you will find the APIs postman collection of resident-services.

  • Swagger is an interface description language for describing restful APIs expressed using JSON. You can access Swagger-UI of resident-services for dev-environment from https://api-internal.dev.mosip.net/resident/v1/swagger-ui.html and localhost from http://localhost:8099/resident/v1/swagger-ui.html.

  • Download the JSON collection available below and import in your postman. Resident-Service-APIs.postman_collection-latest.json.

  • Create an environment as shown in the image below.

This environment is created for dev. Give the variable name as url and set both the values as https://api-internal.dev.mosip.net.

  • In the similar way, create another environment as shown below.

This environment is created for localhost. Give the variable name as url and set both the values as http://localhost:8099.
