• @khanacademy/wonder-stuff-render-environment-jsdom

The core implementation of a render-gateway service.

Development

2. yarn install
3. yarn start

Once started, you can make code changes. babel-watch takes care of restarting the server automatically to incorporate your changes as you go.

For more information on developing, contributing, and releasing, please see our CONTRIBUTING document.

Environment Variables

Some behaviors are controlled via environment variables.

Variable	Purpose
GAE_SERVICE	This is set by Google Cloud AppEngine in production. It is used to determine the name of the gateway that is executing (see get-gateway-info.js).
GAE_VERSION	This is set by Google Cloud AppEngine in production. It is used to determine the version of the gateway that is executing (see get-gateway-info.js).
KA_ALLOW_HEAPDUMP	During development mode, we support importing heapdump so that heap snapshots can be created on-the-fly. Normally, this is not supported in production. Set KA_ALLOW_HEAPDUMP to enable this during production or testing.
KA_IS_DEV_SERVER	This value is ignored in favour of NODE_ENV. However, if the value of NODE_ENV is not recognized, or the variable does not exist, KA_IS_DEV_SERVER is used to differentiate between production or development mode.
KA_LOG_LEVEL	The default log level is debug. Use this environment variable to specify a different level. Valid options are listed in get-log-level.js.
NODE_ENV	This indicates when certain development or test-mode things should be available. Possible values are test, dev, development, prod, and production. If NODE_ENV is not one of these values, we fallback to KA_IS_DEV_SERVER to determine between production and development.
