A Beta FIT JavaScript SDK is now available in npm.
The FIT JavaScript SDK uses ECMAScript module syntax and requires Node.js v14.0 or higher, or a browser with a compatible JavaScript runtime engine. See the read me for usage.

The current beta version is 0.94.2. The beta versions will have a major version of 0 and a minor version that matches the current release version; indicating the version of the FIT Profile included in the beta release. The build number will increment if there are any hot-fixes to the SDK in between minor releases. The hot-fix releases will not contain any updates to the FIT Profile.
Your feedback on the SDK is greatly appreciated and can be posted to the FIT SDK Developer forum, along with any questions on the SDK.
