Local Setup

Requirements

Steps to run locally

  1. 📦 Install npm dependencies

    npm install

  2. ⚙ Local config

    1. In the taas-apis root directory create .env file with the next environment variables. Values for Auth0 config should be shared with you on the forum.

      # Auth0 config
AUTH0_URL=
AUTH0_AUDIENCE=
AUTH0_AUDIENCE_UBAHN=
AUTH0_CLIENT_ID=
AUTH0_CLIENT_SECRET=
# necessary if you'll utilize email functionality of interviews
INTERVIEW_INVITATION_SENDGRID_TEMPLATE_ID=
INTERVIEW_INVITATION_SENDER_EMAIL=
# Locally deployed services (via docker-compose)
ES_HOST=dockerhost:9200
DATABASE_URL=postgres://postgres:postgres@dockerhost:5432/postgres
BUSAPI_URL=http://dockerhost:8002/v5
      • Values from this file would be automatically used by many npm commands.
      • ⚠️ Never commit this file or its copy to the repository!

    2. Set dockerhost to point the IP address of Docker. Docker IP address depends on your system. For example if docker is run on IP 127.0.0.1 add a the next line to your /etc/hosts file:

      127.0.0.1       dockerhost

      Alternatively, you may update .env file and replace dockerhost with your docker IP address.

  3. 🚢 Start docker-compose with services which are required to start Topcoder TaaS API locally

    npm run services:up

    Wait until all containers are fully started. As a good indicator, wait until taas-es-processor successfully started by viewing its logs:

    npm run services:logs -- -f taas-es-processor
    Click to see a good logs example
    • first it would be waiting for kafka-client to create all the required topics and exit, you would see:
    tc-taas-es-processor  | Waiting for kafka-client to exit....
    • after that, taas-es-processor would be started itself. Make sure it successfully connected to Kafka, you should see 9 lines with text Subscribed to taas.:

    If you want to learn more about docker-compose configuration
    see more details here

    This docker-compose file starts the next services:

    Service Name Port
    PostgreSQL postgres 5432
    Elasticsearch elasticsearch 9200
    Zookeeper zookeeper 2181
    Kafka kafka 9092
    tc-bus-api tc-bus-api 8002
    taas-es-processor taas-es-processor 5000

    • as many of the Topcoder services in this docker-compose require Auth0 configuration for M2M calls, our docker-compose file passes environment variables AUTH0_CLIENT_ID, AUTH0_CLIENT_SECRET, AUTH0_URL, AUTH0_AUDIENCE, AUTH0_PROXY_SERVER_URL to its containers. docker-compose takes them from .env file if provided.

    • docker-compose automatically would create Kafka topics which are used by taas-es-processor listed in local/kafka-client/topics.txt.

    • To view the logs from any container inside docker-compose use the following command, replacing SERVICE_NAME with the corresponding value under the Name column in the above table:

      npm run services:log -- -f SERVICE_NAME

    • If you want to modify the code of any of the services which are run inside this docker-compose file, you can stop such service inside docker-compose by command docker-compose -f local/docker-compose.yml stop <SERVICE_NAME> and run the service separately, following its README file.

    NOTE: In production these dependencies / services are hosted & managed outside Topcoder TaaS API.

  4. ♻ Init DB, ES

    npm run local:init

    This command will do 3 things:

    • create Database tables (drop if exists)
    • create Elasticsearch indexes (drop if exists)
    • import demo data to Database and index it to ElasticSearch (clears any existent data if exist)

  5. 🚀 Start Topcoder TaaS API

    npm run dev

    Runs the Topcoder TaaS API using nodemon, so it would be restarted after any of the files is updated. The Topcoder TaaS API will be served on http://localhost:3000.

Import and Export data

📤 Export data

To export data to the default file data/demo-data.json, run:

npm run data:export

If you want to export data to another file, run:

npm run data:export -- --file path/to-file.json
  • List of models that will be exported are defined in scripts/data/exportData.js.

📥 Import data

⚠️ This command would clear any existent data in DB and ES before importing.

During importing, data would be first imported to the database, and after from the database it would be indexed to the Elasticsearch index.

To import data from the default file data/demo-data.json, run:

npm run data:import

If you want to import data from another file, run:

npm run data:import -- --file path/to-file.json
  • List of models that will be imported are defined in scripts/data/importData.js.

Kafka commands

If you've used docker-compose with the file local/docker-compose.yml during local setup to spawn kafka & zookeeper, you can use the following commands to manipulate kafka topics and messages: (Replace TOPIC_NAME with the name of the desired topic)

Create Topic

docker exec tc-taas-kafka /opt/kafka/bin/kafka-topics.sh --create --zookeeper zookeeper:2181 --partitions 1 --replication-factor 1 --topic TOPIC_NAME

List Topics

docker exec tc-taas-kafka /opt/kafka/bin/kafka-topics.sh --list --zookeeper zookeeper:2181

Watch Topic

docker exec tc-taas-kafka /opt/kafka/bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic TOPIC_NAME

Post Message to Topic (from stdin)

docker exec -it tc-taas-kafka /opt/kafka/bin/kafka-console-producer.sh --broker-list localhost:9092 --topic TOPIC_NAME
  • Enter or copy/paste the message into the console after starting this command.

DB Migration

  • npm run migrate: run any migration files which haven't run yet.
  • npm run migrate:undo: revert most recent migration.

Configuration for migration is at ./config/config.json.

The following parameters can be set in the config file or via env variables:

  • username: set via env DB_USERNAME; datebase username
  • password: set via env DB_PASSWORD; datebase password
  • database: set via env DB_NAME; datebase name
  • host: set via env DB_HOST; datebase host name

Testing

  • Run npm run test to execute unit tests
  • Run npm run cov to execute unit tests and generate coverage report.

📋 Code Guidelines

General Requirements

  • Split code into reusable methods where applicable.
  • Lint should pass.
  • Unit tests should pass.

Documentation and Utils

When we add, update or delete models and/or endpoints we have to make sure that we keep documentation and utility scripts up to date.

  • Swagger
  • Postman
  • ES Mapping
  • Reindex
    • NPM command index:all should re-index data in all ES indexes.
    • There should be an individual NPM command index:* which would re-index data only in one ES index.
  • Import/Export
    • NPM commands data:import and data:export should support importing/exporting data from/to all the models.
  • Create/Delete Index
    • NPM commands create-index and delete-index should support creating/deleting all the indexes.
  • DB Migration
    • If there are any updates in DB schemas, create a DB migration script inside migrations folder which would make any necessary updates to the DB schema.
    • Test, that when we migrate DB from the previous state using npm run migrate, we get exactly the same DB schema as if we create DB from scratch using command npm run init-db force.
