warning Similar to Facebook's (FB) invariant but only logs a warning if the condition is not met. This can be used to log issues in development environments in critical paths.

invariant 如名字所示，在关键地方提供个条件，来让

invariant(condition, '抛出异常如果条件错误');

debug 可以配合环境变量 DEBUG 来开启部分输出

var debug = require('debug')('http')
debug('booting %o', name);
