Promise.config
Promise.config(Object {
warnings: boolean=false,
longStackTraces: boolean=false,
cancellation: boolean=false,
monitoring: boolean=false
} options) -> Object;
Configure long stack traces, warnings, monitoring and cancellation. Note that even though false
is the default here, a development environment might be detected which automatically enables long stack traces and warnings.
Promise.config({
// Enable warnings
warnings: true,
// Enable long stack traces
longStackTraces: true,
// Enable cancellation
cancellation: true,
// Enable monitoring
monitoring: true
});
You can configure the warning for checking forgotten return statements with wForgottenReturn
:
Promise.config({
// Enables all warnings except forgotten return statements.
warnings: {
wForgottenReturn: false
}
});
wForgottenReturn
is the only warning type that can be separately configured. The corresponding environmental variable key is BLUEBIRD_W_FORGOTTEN_RETURN
.
In Node.js you may configure warnings and long stack traces for the entire process using environment variables:
BLUEBIRD_LONG_STACK_TRACES=1 BLUEBIRD_WARNINGS=1 node app.js
Both features are automatically enabled if the BLUEBIRD_DEBUG
environment variable has been set or if the NODE_ENV
environment variable is equal to "development"
.
Using the value 0
will explicitly disable a feature despite debug environment otherwise activating it:
# Warnings are disabled despite being in development environment
NODE_ENV=development BLUEBIRD_WARNINGS=0 node app.js
Cancellation is always configured separately per bluebird instance.
