SDK: payload hydration, experiment blocking, enhanced auto-wrapper

[bryce-fitzsimons]

Features and Changes

• v1.0.0 of JS and React SDKs
• Enhanced auto wrapper SDK

From the changelog:

• New init function as a replacement for loadFeatures.
• Support payload import/export via init({ payload }), setPayload, and getPayload. Better supports hybrid apps, as well as externalizing the SDK Payload.
• Ability to block or control experiments by various context properties
  • blockedChangeIds targets individual experiments
  • disableVisualExperiments prevents visual experiments from running
  • disableJsInjection blocks any visual experiments which write <script> code
  • disableUrlRedirectExperiments prevents redirect experiments from running
  • disableCrossOriginUrlRedirectExperiments blocks redirects if the origin changes
  • jsInjectionNonce injects a nonce string onto any generated <sript> tags
  • disableExperimentsOnLoad prevents AutoExperiments from running automatically; triggerAutoExperiments manually triggers them.
• Provide a custom DOM mutation method by setting context applyDomChangesCallback. Useful for server-side rendering visual experiments.
• Get a list of triggered experiments by their changeId (a new, more-specific AutoExperiment identifier) via getCompletedChangeIds.
• Disable in-memory cache via configureCache({ disableLocalCache: true })
• Easier streaming customization via init({ streaming: true }).
• Prefetch payloads on backend SDK instances via prefetchPayload(). Also allows feature repository SSE streaming without connection each SDK instance to streaming (useful for NodeJS).
• Many improvements to auto.min.js script
  • Payload hydration via payload context property
  • Support sticky bucketing via useStickyBucketService context property (accepts "cookie" and "localStorage"); override cookie or localStorage key via stickyBucketPrefix context property.
  • Hydrate sticky bucket docs by setting context stickyBucketAssignmentDocs (useful for SSR hydration without reliance on cookies)
  • Customize attributes/cookies via uuidCookieName (default "gbuuid") and uuidKey (default "id").
  • Force a uuid cookie write on load via persistUuidOnLoad (useful for SSR hydration)
