v2.x

worker support

• Set up yarn start-local or yarn start-local-worker to use local workers.
• Add documentation about how to copy worker scripts to app to avoid relying on CDN (partly done)
• Add debug option to debug workers - add logging and/or break in debugger
• Finalize worker override system/security audit (options vs dedicated API etc)
• New API initializeWorkers([DracoWorkerLoader, ...]) (let app preload worker scripts before parsing is needed for reduced "time to first pixel")
• Better control of max concurrency (global options, per-loader options, auto detect number of cores, ...)

stats

• time worker startup times
• time parsers
• Export stats object from loaders.gl
• Total time in parsers
• Total time in parsers on main thread
• Time to first data (SSL initialization etc)

embedded binaries

• Flag to indicate whether binary loader supports offsets or whether arraybuffer copy is needed before invocation?
• Implement arraybuffer copy before call if needed (auto detect alignment issues?)
• DracoLoader: Binary test function handle typed arrays with offsets (embedded binaries): byteOffset, byteLength
• Ability to parse embedded binaries on workers (byteOffset, byteLength) (copy and transfer?)
• Binary test function handle typed arrays with offsets (embedded binaries): byteOffset, byteLength

v2.0

• Build ES6/ES2018 debug workers for all loaders
• Build ES6/ES2018 debug workers - Draco only
• Conditional workers (Image only when imagebitmap output, CSV, JSON only when binary output etc) @ibgreen
• Update worker override system (loader-specific options) @ibgreen
• Conditional worker support: loader.useWorker(options) @ibgreen
• Support calling "worker parsers" from other worker parsers @Pessimistress
• Support calling "async parsers" from workers @Pessimistress

loader objects

• Remove loadAndParse

loader registry and selection

• registry is currently a map with each extension, which causes same loader to be tests many times...
• More rigorous selection, documented semantics, public API
