var codes = require('statuses/codes.json');

This is a JSON file of the status codes taken from require('http').STATUS_CODES. This is saved so that codes are consistent even in older node.js versions. For example, 308 will be added in v0.12.

The status codes are primarily sourced from http://www.iana.org/assignments/http-status-codes/http-status-codes-1.csv. Additionally, custom codes are added from http://en.wikipedia.org/wiki/List_of_HTTP_status_codes. These are added manually in the lib/*.json files. If you would like to add a status code, add it to the appropriate JSON file.

To rebuild codes.json, run the following:

# update src/iana.json
npm run update
# build codes.json
npm run build
