gw2-api.com

Proxy-layer server for the official GuildWars 2 API.

NO LONGER MAINTAINED, MAY BREAK AT ANY POINT

In the old days, before the official API, you could get item and price data by requesting a session token from the official login page and then using the urls the tradingpost used ingame as a unofficial API. This project originated when I wanted to this data for a tradingpost section on gw2efficiency.com, but I was not satisfied with the existing solutions (mainly because of cache time, update frequency and data format).

Now, most of this code is integrated into the internal API of gw2efficiency.com directly and this code is not longer maintained (even tho it may remain usable). This repository is mainly online for historical reasons.

Install

• Requirements:
  • MongoDB as the database layer (use wiredTiger!)
  • Redis for the priority job queue
  • A process manager to keep the processes running, in this example pm2
  • (Optional) Some sort of caching like Varnish

# Clone the repository
git clone https://github.com/gw2efficiency/gw2-api.com
cd gw2-api.com/

# Install the dependencies and build all files
npm install
npm run build

# Build the initial database using the cli tool
node build/bin/cli.js full-rebuild

# Start the job worker process
pm2 start build/bin/worker.js --name="gw2api-worker"

# Start the job scheduling
pm2 start build/bin/scheduler.js --name="gw2api-scheduler"

# Start the job monitoring interface (port 3000)
pm2 start build/bin/kue.js --name="gw2api-kue"

# Start a server cluster for API routes (port 8080)
pm2 start build/bin/server.js --name="gw2api-server" -i 3

Logs for all processes will be written in ~/.pm2/logs.

CLI

You can fire off any jobs using the included cli tool, either directly in the cli process or as usual as a queued job, which gets processed by the worker processes:

node build/bin/cli.js <job-name> # Execute job in this process
node build/bin/cli.js <job-name> -q # Push the job in the queue

The following jobs exist:

• full-rebuild (clear the database and execute all jobs)
• item-list (get all items)
• item-prices (update the item prices)
• item-values (calculate the item values)
• recipe-list (get all recipes)
• crafting-prices (calculate the crafting prices)
• skin-list (get all skins)
• skin-prices (calculate all skin prices)
• gem-price-history (get the gem price history)
• item-last-known-prices (get the last known sell prices, if they are missing)

Running in production

When running the servers in production, use the NODE_ENV environment variable to set the environment to production. Note that this will load the config/environment.production.js configuration, so you will have to copy the default config/environment.js and make sure the values match your setup.

NODE_ENV=production pm2 start build/bin/worker.js --name="gw2api-worker"
NODE_ENV=production pm2 start build/bin/scheduler.js --name="gw2api-scheduler"
NODE_ENV=production pm2 start build/bin/kue.js --name="gw2api-kue"
NODE_ENV=production pm2 start build/bin/server.js --name="gw2api-server" -i 3

Tests

Note: Requires a running instance of mongodb and will execute on a test database. Also requires a running instance of redis and will flush all existing jobs.
