-/**
- * TDLib in a browser
- *
- * TDLib can be compiled to WebAssembly or asm.js using Emscripten compiler and used in a browser from JavaScript.
- * This is a convenient wrapper for TDLib in a browser which controls TDLib instance creation, handles interaction
- * with TDLib and manages a filesystem for persistent TDLib data.
- * TDLib instance is created in a Web Worker to run it in a separate thread.
- * TdClient just sends queries to the Web Worker and receives updates and results from it.
- * <br>
- * <br>
- * Differences from the TDLib JSON API:<br>
- * 1. Added the update <code>updateFatalError error:string = Update;</code> which is sent whenever TDLib encounters a fatal error.<br>
- * 2. Added the method <code>setJsLogVerbosityLevel new_verbosity_level:string = Ok;</code>, which allows to change the verbosity level of tdweb logging.<br>
- * 3. Added the possibility to use blobs as input files via the constructor <code>inputFileBlob data:<JavaScript blob> = InputFile;</code>.<br>
- * 4. The class <code>filePart</code> contains data as a JavaScript blob instead of a base64-encoded string.<br>
- * 5. The methods <code>getStorageStatistics</code>, <code>getStorageStatisticsFast</code>, <code>optimizeStorage</code>, <code>addProxy</code> and <code>getFileDownloadedPrefixSize</code> are not supported.<br>
- * <br>

All but one instances with the same name will be automatically closed. Usually, the newest non-background instance is kept alive. Files will be stored in an IndexedDb table with the same name.

-   * @param {boolean} [options.useDatabase=true] - Pass false to use TDLib without database and secret chats. It will significantly improve loading time, but some functionality will be unavailable.
-   * @param {boolean} [options.readOnly=false] - For debug only. Pass true to open TDLib database in read-only mode
-   * @param {string} [options.mode=auto] - For debug only. The type of the TDLib build to use. 'asmjs' for asm.js and 'wasm' for WebAssembly. If mode == 'auto' WebAbassembly will be used if supported by browser, asm.js otherwise.
