Using the Toggles

Add the following to your <head></head>.

<script src="https://unpkg.com/@blaze/toggles@x.x.x/dist/collection/config.js"></script>
<script src="https://unpkg.com/@blaze/toggles@x.x.x/dist/toggles.js"></script>

The x.x.x is the specific version of the library, you should use specifc versions to prevent against breaking changes.

Config

Next add some feature toggle config, e.g.

FeatureToggles.set({
  welcomeMessage: true,
  loginPage: {
    rememberMe: 'alpha',
  },
});

You can call FeatureToggles.set({...}) at anytime to update config. Everytime FeatureToggles.set is called it raises a featureToggleChange event that you can hook into.

set also merges the config with the already set config.

Config values can be either booleans, strings or functions.

Promises are supported.

e.g. the below to toggle the feature after 2 seconds once the promise has resolved.

FeatureToggles.set({
  welcomeMessage: true,
  loginPage: {
    rememberMe: () => new Promise((resolve) => setTimeout(() => resolve('alpha'), 2000)),
  },
});
