Version 4.0.0

Breaking changes from version 3.* to 4.0.0

  • WARNING: If you need 4.0.0 to work with data stored under 3.*, you need to add a callback as the value of the new CFG.registerSCA config with a value set to the function exported from typeson-registry-sca-reverter, and do so before you make your indexedDB calls. This code was part of IndexedDBShim, but is no longer bundled with it, as IndexedDBShim, as of version 4.0.0 is now using the new typeson-registry Structured Cloning Algorithm format by default for representing cloneable data as JSON.
  • Representation of Arrays were changed to allow storage of non-index properties (courtesy of updated typeson-registry)
  • Representation of Blobs was changed to store as binary to avoid UTF16 representation dropping unpaired surrogates (courtesy of updated typeson-registry); also assumes XHR has overrideMimeType
  • Breaking change: webkitGetDatabaseNames removed in favor of now-standard databases (see https://github.com/w3c/IndexedDB/pull/240/files)
  • We removed Bower support completely (the service has deprecated itself per https://bower.io). npm or yarn can be used instead.
  • Due to changes from Babel 6 to Babel 7, the polyfill required for IndexedDB to work on older browsers and environments (assuming IndexedDBShim currently supports them), script tag references to node_modules-based paths of babel-polyfill will need to be changed to @babel/polyfill
  • IDBDatabase.prototype.transaction's second argument' had previously accepted numeric constants in IndexedDB, but IndexedDBShim deprecated their use, and now we are dropping support. Please use "readonly" or "readwrite" instead.
  • We removed our non-standard IDBFactory.modules as this legacy holder of non-IDB shims such as DOMException are already available as shims or polyfills by using CFG.addNonIDBGlobals or CFG.replaceNonIDBGlobals, respectively, with shim names prefixing class names with "Shim".
  • We removed our non-standard IDBFactory.utils and moved its test utility createDOMException to become a named export of setGlobalVars.js
