Local Setup

Requirements

Steps to run locally

Make sure to use Node v12+ by command node -v. We recommend using NVM to quickly switch to the right version:
```
nvm use
```
📦 Install npm dependencies
```
npm install
```

⚙ Local config

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=
# If you would like to test Interview Workflow then Config Nylas as per ./docs/guides/Setup-Interview-Workflow-Locally.md
NYLAS_CLIENT_ID=
NYLAS_CLIENT_SECRET=
NYLAS_SCHEDULER_WEBHOOK_BASE_URL=
# Locally deployed services (via docker-compose)
ES_HOST=http://dockerhost:9200
DATABASE_URL=postgres://postgres:postgres@dockerhost:5432/postgres
BUSAPI_URL=http://dockerhost:8002/v5
TAAS_API_BASE_URL=http://localhost:3000/api/v5
# stripe
STRIPE_SECRET_KEY=
CURRENCY=usd

Values from this file would be automatically used by many npm commands.
⚠️ Never commit this file or its copy to the repository!

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.

🚢 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.

♻ 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)
🚀 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.
- 💡 If you would like to test Interview Workflow locally, then follow the guide How to Setup Interview Workflow Locally.

Working on `taas-es-processor` locally

When you run taas-apis locally as per "Steps to run locally" the taas-es-processor would be run for you automatically together with other services inside the docker container via npm run services:up.

To be able to change and test taas-es-processor locally you can follow the next steps:

Stop taas-es-processor inside docker by running docker-compose -f local/docker-compose.yml stop taas-es-processor
Run taas-es-processor separately from the source code. As npm run services:up already run all the dependencies for both taas-apis and for taas-es-processor. The only thing you need to do for running taas-es-processor locally is clone the taas-es-processor repository and inside taas-es-processor folder run:
- nvm use - to use correct Node version
- npm run install
- 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_CLIENT_ID=
AUTH0_CLIENT_SECRET=
```
  - Values from this file would be automatically used by many npm commands.
  - ⚠️ Never commit this file or its copy to the repository!
- npm run start

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.

Email Notifications

We have various email notifications. For example many emails are sent to support Interview Scheduling Workflow. All email templates are placed inside the .data/notification-email-templates folder.

Add a new Email Notification

To add a new email notification:

Each email notification need to have a unique topic identifier of the shape taas.notification.{notification-type}. Where {notification-type} is unique for each email notification type.
Create a new HTML template inside folder .data/notification-email-templates. (You may duplicate any existent template to reuse existent styles.). Name it the same as topic: taas.notification.{notification-type}.html.
Create a corresponding config in file ./config/email_template.config.js, section notificationEmailTemplates.
Name environment variable the same as topic, but uppercase and replace all special symbols to _ and add suffix _SENDGRID_TEMPLATE_ID:
- For example topic taas.notification.job-candidate-resume-viewed would have corresponding environment variable TAAS_NOTIFICATION_JOB_CANDIDATE_RESUME_VIEWED_SENDGRID_TEMPLATE_ID.
When deploying to DEV/PROD someone would have to create a new Sendgird template and fill inside Sendgrid UI subject and email HTML template by copy/pasting HTML file from the repo. And then set environment variable with the value of template if provided by Sendgrid.

Test/Render Email Notifications Locally

To test and render email notification locally run a special script npm run demo-email-notifications. Before running it, follow it's README as you would have to set some additional environment variables first (add them into .env file).

This script first would update demo data to create some situations to trigger notifications.
And it would listen to Kafka events and render email notification into ./out folder.

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:

url: set via env DATABASE_URL; datebase url

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
- Update mapping definitions for ElasticSearch indexes inside both repositories taas-apis and taas-es-processor.
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.

EMSI mapping

mapping EMSI tags to topcoder skills Run npm run emsi-mapping to create the mapping file It will take about 15 minutes to create the mapping file script/emsi-mapping/emsi-skils-mapping.js
