Talent Catalog

Overview

This is the repository for the Talent Catalog (TC), which manages data for refugees looking for skilled migration pathways into safe countries and employment.

This repository is a "mono-repo", meaning it contains multiple sub-modules all of which make up the TC system. In particular, it contains:

  • server: the backend module of the system providing secure API (REST) access to the data, stored in an SQL Database. This module is written in Java / Spring Boot.
  • candidate-portal: the frontend module through which candidates (refugees seeking skilled migration) are able to register and manage their details. This is written in Angular and connects to the REST API endpoints under /api/candidate provided by the server.
  • admin-portal: the frontend module through which admin staff are able to view, manage and annotate candidate details. This is written in Angular and connects to the REST API endpoints under /api/admin provided by the server.
  • public-portal: a module through which anyone can access publicly available data. This is written in Angular and connects to the REST API endpoints under /api/public provided by the server.

How do I get set up?

Install the tools

IMPORTANT NOTE:

These instructions are tailored for Mac users using Intellij, as this is what we use for development.

On a Mac, installing with Homebrew usually works well. eg "brew install xxx".

It is also probably easier to install Java directly (or from your development IDE - see below) rather than using brew.

Download and install the latest of the following tools.

  • Homebrew - Homebrew website

  • IntelliJ IDEA - Intellij website

    • Import standard settings and run configurations from another developer
    • In development, it is best to build using Intellij rather than gradle. Change the Intellij setting for "Build, Execution & Deployment" > "Build Tools" > "Gradle" to build with Intellij.
  • Java 17

    • The current version of Java supported is Java 17. We use the Temurin release (however there should be no issues using other releases). One way (but you can choose whichever method you like) to manage Java versions is with sdkman. A .sdkmanrc file exists when you check out the repository. You can get sdkman by running the following:

      curl -s "https://get.sdkman.io" | bash
      source "$HOME/.sdkman/bin/sdkman-init.sh"
      sdk install 17.0.11-tem
      
    • Intellij will load the JDK through the .sdkmanrc file.

    • Update the Project SDK:

      • Go to File / Project Structure / Project and set the SDK to your chosen JDK.
      • On the same page, ensure the language level matches your chosen SDK version.
    • IntelliJ Settings:

      • Go to IntelliJ / Settings / Build,Execution,Deployment / Compiler / Java Compiler
        • Add -parameters to theAdditional command line parameters textbox.
        • Set the Project bytecode version to match the JDK chosen (e.g. 17).
      • Go to IntelliJ / Settings / Build,Execution,Deployment / Build Tools / Gradle
        • Set the GradleJVM from the drop list to use the Project SDK.
  • Code Style

    • Download the intellij-java-google-style.xml file from the google/styleguide repository here.
    • Launch IntelliJ and go to the IntelliJ > Settings... menu and expand the Code Style sub-menu underneath Editor. Here, you will see a list of supported languages. Select Java.
    • Next to the Scheme drop-down menu select the gear icon then Import Scheme > IntelliJ IDEA code style XML then select the intellij-java-google-style.xml file you downloaded from GitHub.
    • Give the schema a name (or use the default GoogeStyle name from the import). Click OK or Apply for the settings to take effect.
  • Gradle https://gradle.org/install/

    brew install gradle
    
  • Node https://nodejs.org/en/

    brew install node@18
    
    • Note the messages from brew at the end of the install. You will have to manually set up the path.
  • Angular CLI https://angular.io/cli

    npm install -g @angular/cli@16
    
  • Git - see Git website - Not really necessary now with Intellij which will prompt you to install Git if needed.

  • Docker and docker-compose

    • Install Docker Desktop for Mac - see docker website
    • Note for Mac Silicon users. The current Docker doc (link above) implies that installing Rosetta is optional. But if you don't do it you won't be able to install Docker. You need to execute softwareupdate --install-rosetta just to run Docker for the first time after installing it.
    • When you install Docker Desktop for Mac, Docker Compose is bundled with it. You can verify the installation by running:
        docker-compose --version

Clone the TC repository from Git

git clone https://github.com/Talent-Catalog/talentcatalog.git
  • Open the root folder in IntelliJ IDEA (it should auto detect gradle and self-configure)

Using Docker-Compose to Start Services

With Docker and Docker Compose installed, you can now use docker-compose to set up the required services: PostgreSQL, Redis, Elasticsearch, and optionally, Kibana.

  • The TC repository includes a docker-compose.yml file in the docker-compose folder, with preconfigured services for PostgreSQL, Redis, Elasticsearch, and Kibana. This file is ready for you to use.
  • To start the services, navigate to the docker-compose folder and run the following command:
cd talentcatalog/docker-compose
docker-compose up -d
  • The -d flag runs the services in detached mode.
  • To stop the services, run the following command:
docker-compose down

Using IntelliJ’s Docker-Compose Integration to Start Services

IntelliJ IDEA provides built-in support for Docker Compose, allowing you to start and stop services directly from the IDE, either from the Services tool window or directly from the docker-compose.yml file itself.

  • In the Project tool window, navigate to and open the docker-compose.yml file.
  • IntelliJ adds green Run/Debug triangles in the gutter (left margin) next to each service in the docker-compose.yml file.
  • Click on the green Run triangle next to a service (e.g., postgres or redis) to start that specific service.
  • You can also click the Run triangle next to the services block at the top of the file to start all services at once.

Verify Services

The following services will all run from the Docker container:

  • PostgreSQL (listening on port 5432)
  • Redis (6379)
  • Elasticsearch (9200)
  • Kibana (5601)

Verify with the following terminal command:

docker ps

AWS management tools

These tools do not need to be installed in order to get the code up and running on your development machine. However, they are needed if you want to build the TC's AWS cloud infrastructure from the Terraform definitions in the infra folder.

Once installed, needs to be configured. Log in to your AWS account, click on user top right, select Security Credentials, create access key, then download to CSV file. Then, theoretically this should work

aws configure import --csv path-to-downloaded-file.csv

...but it doesn't currently (it fails saying that it is missing a User Name header). Instead, just run this and manually copy/paste the values from the CSV file as prompted.

aws configure
  • Terraform (for setting up our AWS infrastructure)
    brew install terraform 
    

Once installed, you can run Terraform from the directory containing your main Terraform file (main.tf). In order to populate "secret" configuration values that Terraform needs to set up as environment variables for the TC software, you need to copy a special file terraform.tfvars to that directory before running terraform. Contact support@talentcatalog.net for a copy of that file.

Then you can run init (only need to do this once), and then plan or apply, as needed.

terraform init
terraform plan
terraform apply

Set up your local database

Ask TC developers for a pg_dump of the database. Note that the dump does not have to be recent. The software will automatically apply any required updates to the database definition, driven by Flyway files stored in GitHub.

A standard dump file is kept specifically for getting new developers started, but TC developers can also quickly create a new one from their local containerised version with the following commands:

docker exec -it docker-compose-postgres-1 pg_dump --file=/tmp/dump.sql --create --username=tctalent --host=localhost --port=5432
docker cp docker-compose-postgres-1:/tmp/tcdump.sql </path/to/file>   

Once you have the dump, run Docker-Compose and check that your newly created tctalent database and user are up and running by accessing the psql console:

docker exec -it docker-compose-postgres-1 psql -U tctalent -d tctalent

It should open with tctalent=# as prompt. If you get an error, return to the Docker-Compose setup process.

Otherwise, \q will exit the console. You can then copy the dump file to your Docker container and use it to populate your empty database:

docker cp <path/to/file> docker-compose-postgres-1:/tmp/dump.sql
docker exec -it docker-compose-postgres-1 psql -U tctalent -d tctalent -f /tmp/dump.sql

Connect IntelliJ to your database

  • File > New > Data Source > PostgreSQL > PostgreSQL
  • Give the DB a name that clearly identifies it as your local development version.
  • Populate the other setup parameters with the default values in the postgres configuration of the project file docker-compose.yml.

Run the server

  • Some secret information such as passwords and private keys are set in environment variables - including programmatic access to TC's Amazon AWS, Google and Salesforce accounts. If these environment variables are not set the application will fail at start up. Contact other TC developers for a copy of a "secrets" file suitable for developers. On development computers you hook the file, tc_secrets.txt, into your computer's start up to set the relevant environment variables. For example add "source ~/tc_secrets.txt" to .bash_profile or .zshenv depending on whether you are running bash or zsh.

  • Create a new Run Profile for org.tctalent.server.TcTalentApplication. In the Environment Variables section of Intellij, check the "Include system environment variables" checkbox.

  • Run the new profile, you should see something similar to this in the logs:

Started TcTalentApplication in 2.217 seconds (JVM running for 2.99)
  • your server will be running on port 8080 (default for Spring Boot) (can be overridden by setting server.port in application.yml, or Intellij Run Configuration, and updating environment.ts in portals)
  • To test it open a browser to http://localhost:8080/test

Run the Candidate Portal

The "Candidate Portal" is an Angular Module and can be found in the directory talentcatalog\ui\candidate-portal.

Before running, make sure all the libraries have been downloaded locally by running npm install from the root directory of the module (i.e. talentcatalog\ui\candidate-portal):

cd talentcatalog\ui\candidate-portal
npm install

It is also a good idea to install fsevents for MacOS which will greatly reduce your CPU usage

npm install fsevents
npm rebuild fsevents

Then from within the same directory run:

ng serve

You will see log similar to:

chunk {main} main.js, main.js.map (main) 11.9 kB [initial] [rendered]
chunk {polyfills} polyfills.js, polyfills.js.map (polyfills) 236 kB [initial] [rendered]
chunk {runtime} runtime.js, runtime.js.map (runtime) 6.08 kB [entry] [rendered]
chunk {styles} styles.js, styles.js.map (styles) 16.6 kB [initial] [rendered]
chunk {vendor} vendor.js, vendor.js.map (vendor) 3.55 MB [initial] [rendered]
i 「wdm」: Compiled successfully.

The Candidate Portal is now running locally and you can open a browser (chrome preferred) to:

http://localhost:4200

Note: this is for development mode only. In production, the Candidate Portal module will be bundled into the server and serve through Apache Tomcat.

Run the Public Portal

The "Public Portal" is an Angular Module and can be found in the directory talentcatalog\ui\public-portal.

As for the "Candidate Portal", make sure all libraries are installed locally.

Then from within the same directory run:

ng serve

You will see log similar to:

chunk {main} main.js, main.js.map (main) 11.9 kB [initial] [rendered]
chunk {polyfills} polyfills.js, polyfills.js.map (polyfills) 236 kB [initial] [rendered]
chunk {runtime} runtime.js, runtime.js.map (runtime) 6.08 kB [entry] [rendered]
chunk {styles} styles.js, styles.js.map (styles) 16.6 kB [initial] [rendered]
chunk {vendor} vendor.js, vendor.js.map (vendor) 3.55 MB [initial] [rendered]
i 「wdm」: Compiled successfully.

The Public Portal is now running locally and you can open a browser (chrome preferred) to:

http://localhost:4202

Note: this is for development mode only. In production, the Public Portal module will be bundled into the server and serve through Apache Tomcat.

Run the Admin Portal

The "Admin Portal" is an Angular Module and can be found in the directory talentcatalog\ui\admin-portal.

As for the "Candidate Portal", make sure all libraries are installed locally.

Then from within the same directory run:

ng serve

You will see log similar to:

chunk {main} main.js, main.js.map (main) 11.9 kB [initial] [rendered]
chunk {polyfills} polyfills.js, polyfills.js.map (polyfills) 236 kB [initial] [rendered]
chunk {runtime} runtime.js, runtime.js.map (runtime) 6.08 kB [entry] [rendered]
chunk {styles} styles.js, styles.js.map (styles) 16.6 kB [initial] [rendered]
chunk {vendor} vendor.js, vendor.js.map (vendor) 3.55 MB [initial] [rendered]
i 「wdm」: Compiled successfully.

The Admin Portal is now running locally and you can open a browser (chrome preferred) to:

http://localhost:4201

Note: this is for development mode only. In production, the Admin Portal module will be bundled into the server and serve through Apache Tomcat.

Log In To The Admin Portal

  • On startup, the server automatically creates a default user with username SystemAdmin and password password that can be used to log in to the admin portal in development.
  • Details about this user can be found in org/talentcatalog/server/configuration/SystemAdminConfiguration.java

Populate ElasticSearch from Postgres Database

  • Log in to Admin Portal as SystemAdmin, go to Settings | Admin API and make API call esload

Upgrades

Angular

See https://update.angular.io

Note that you have to separately upgrade each of the Angular directories:

  • ui/admin-portal
  • ui/candidate-portal
  • ui/public-portal

Assuming that the package.json in each of the above directories has the right versions already in there you just need run the following commands in each directory.

npm install 

Note and fix any errors. "npm outdated" is good for identifying outdated libraries "npm update --save" will update versions to the latest version within the allowed versions specified by the package.json.

Once all versions are updated for the current version of Angular, you can run the Angular update as follows.

ng update

This will prompt you to update the Angular core and cli. For example:

ng update @angular/core@13 @angular/cli@13

This will update package.json with the appropriate Angular versions which will drive updates of other dependent libraries.

You may find that you need to manually upgrade versions of some tools in package.json so that they work with the new version of Angular. For example, you might need to upgrade the version of ng-bootstrap to a version that works with the later version of Angular. Look at the doc of the library in question to select the correct version

You may also need to make changes to your Angular code because of changes in Angular, or because of changed APIs in the dependent libraries.

Version Control

We use GitHub. Our repository is called talentcatalog - https://github.com/Talent-Catalog/talentcatalog

See the GitHub wiki for additional documentation.

Master branch

The main branch is "master". We only merge and push into "master" when we are ready to deploy to production (rebuild and upload of build artifacts to the production environment is automatic, triggered by any push to "master". See Deployment section below).

Master should only be accessed directly when staging is merged into it, triggering deployment to production. You should not do normal development in Master.

Staging branch

The "staging" branch is used for code which is potentially ready to go into production. Code is pushed into production by merging staging into master and then pushing master. See Deployment section below.

Staging is a shared resource so you should only push changes there when you have finished changes which you are confident will build without error and should not break other parts of the code.

As a shared resource, staging is the best way to share your code with other team members to allow them to merge your code into their own branches and also to allow them to review your code and help with testing.

Rebuild and upload of build artifacts to the AWS testing environment is automatic when any push is made to "staging".

Personal branches

New development should be done in branches.

Typically, you should branch from the staging branch, and merge regularly (eg daily) from staging so that your code does not get too far away from what everyone else is doing.

When you are ready to share your code for others to take a look at and for final joint testing and eventual deployment, merge your branch into staging.

On your branch you should commit often - doing separate commits for specific functionality, rather than lumping different kinds of functionality into a single big commit. That makes commits simpler to review and understand. It also makes it easier to revert specific functionality when you have got something wrong and decide to start again, doing it differently.

You should feel comfortable pushing regularly - often doing Commit and Push at the same time. Pushing is effectively saving your work into the "cloud" rather having changes just saved on your computer.
