Build with feature flags in Carbon
To install @carbon/feature-flags
in your project, you will need to run the
following command using npm:
npm install -S @carbon/feature-flags
If you prefer Yarn, use the following command instead:
yarn add @carbon/feature-flags
The @carbon/feature-flags
provides a runtime-based feature flag system that
you can use to enable or disable experimental features from Carbon or in your
own code.
To check if a feature flag is enabled, you can use the enabled
function in
JavaScript:
import { enabled } from '@carbon/feature-flags';
enabled('feature-flag-name');
In Sass, you would use the enabled
function or mixin:
@use '@carbon/feature-flags';
// Return true if the flag is enabled
@if feature-flags.enabled('feature-flag-name') {
//
}
@include enabled('feature-flag-name') {
// only include contents if the flag is enabled
}
You can change whether a feature flag is enabled. In JavaScript, you can use the
enable
, disable
, and merge
functions to accomplish this.
import { enable, disable, merge } from '@carbon/feature-flags';
// Enable `feature-flag-a`
enable('feature-flag-a');
// Disable `feature-flag-a`
disable('feature-flag-a');
// Set a variety of feature flags to a specific value
merge({
'feature-flag-a': true,
'feature-flag-b': false,
'feature-flag-c': true,
});
In Sass, you can configure whether a feature flag is enabled when you include
the module or by using enable
, disable
, and merge
.
@use '@carbon/feature-flags' with (
$feature-flags: (
'feature-flag-a': false,
'feature-flag-b': true,
)
);
// Enable `feature-flag-a`
@include feature-flags.enable('feature-flag-a');
// Disable `feature-flag-b`
@include feature-flags.disable('feature-flag-b');
// Set a variety of feature flags to a specific value
@include feature-flags.merge(
(
'feature-flag-a': true,
'feature-flag-b': true,
)
);
