Environment Variables

This module allows certain configuration to be obtained from environment variables. Configuration passed with the options object overrides environment variables.

• SZ_RIAK_HOST: the riak host to connect to
• SZ_RIAK_PORT: the riak port to connect to
• SZ_RIAK_ASYNC_LIMIT: the maximum number of requests to perform in parallel (mostly affect the m* functions like mget)

Run Tests

  npm test

There must be a local instance of riak running for tests to succeed. Or point to a remote riak instance by setting the SZ_RIAK_HOST environment variable.

Troubleshooting

• I get an error when installing node packages "ERR! Error: No compatible version found: assertion-error@'^1.0.1'"

  If you are running a version of NodeJS less than or equal to 0.8, upgrading NPM to a version greater than or equal to 1.4.6 should solve this issue.

  npm install -g npm@~1.4.6

  Another way around is to simply avoid installing the development dependencies:

  npm install --production
