GraphQL API server for clients like rumors-site and rumors-line-bot

For development, copy .env.sample to .env and make necessary changes.

For production via rumors-deploy, do setups in docker-compose.yml.

• Docker & docker-compose

After cloning this repository & cd into project directory, then install the dependencies.

$ git clone --recursive [email protected]:MrOrz/rumors-api.git # --recursive for the submodules
$ cd rumors-api
$ npm i

If you want to test OAuth2 authentication, you will need to fill in login credentials in .env. Please apply for the keys in Facebook, Twitter and Github respectively.

$ mkdir esdata # For elasticsearch DB
$ docker-compose up

This will:

• rumors-api server on http://localhost:5000. It will be re-started when you update anyfile.
• Kibana on http://localhost:6222.
• ElasticSearch DB on http://localhost:62222.
• URL resolver on http://localhost:4000

To stop the servers, just ctrl-c and all docker containers will be stopped.

Ask a team member to send you nodes directory, then put the nodes directory right inside the esdata directory created in the previous step, then restart the database using:

$ docker-compose restart db

If you do not want a console occupied by docker-compose, you may use detached mode:

$ docker-compose up -d

Access the logs using:

$ docker-compose logs api     # `api' can also be `db', `kibana'.
$ docker-compose logs -f api  # Tail mode

This directory is managed by git submodule. Use the following command to update:

$ npm run rumors-db:pull

# Please check lint before you pull request
$ npm run lint
# Automatically fixes format error
$ npm run lint:fix

To prepare test DB, first start an elastic search server on port 62223:

$ docker run -d -p "62223:9200" --name "rumors-test-db" docker.elastic.co/elasticsearch/elasticsearch-oss:6.3.2
# If it says 'The name "rumors-test-db" is already in use',
# Just run:
$ docker start rumors-test-db

Then run this to start testing:

$ npm t

If you get "Elasticsearch ERROR : DELETE http://localhost:62223/replies => socket hang up", please check if test database is running. It takes some time for elasticsearch to boot.

If you want to run test on a specific file (ex: src/xxx/__tests__/ooo.js), run:

$ npm t -- src/xxx/__tests__/ooo.js

When you want to update jest snapshot, run:

$ npm t -- -u

Build docker image. The following are basically the same, but with different docker tags.

# Production build
$ npm run build

# Staging build
$ npm run build:staging

Run the docker image on local machine, then visit http://localhost:5000. (To test functions involving DB, ElasticSearch DB must work as .env specified.)

$ docker run --rm -it -p 5000:5000 mrorz/rumors-api

Push to dockerhub

# Production
$ docker push mrorz/rumors-api:latest

# Staging
$ docker push mrorz/rumors-api:staging

First, make sure .env is configured so that the correct DB is specified. Then at project root, run:

$ node_modules/.bin/babel-node src/scripts/fillAllHyperlinks.js

This script would scan for all articles & replies to fill in their hyperlinks field, also populates urls index. The urls index is used as cache. If an URL already exists in urls, it will not trigger HTTP request.

The urls index serves as a cache of URL scrapper and will enlarge as ListArticle is invoked with URLs. The following script cleans up those urls that no article & reply currently uses.

$ docker-compose exec api node_modules/.bin/babel-node src/scripts/cleanupUrls.js
