In general, you need to install all `TDLib` [dependencies](#dependencies) as described in [Installing dependencies](#installing-dependencies).

* TDLib in a browser
|
||||
*
|
||||
* TDLib can be used from javascript through the [JSON](https://github.com/tdlib/td#using-json) interface.
|
||||
* This is a convenient wrapper around it.
|
||||
* Internally it uses TDLib built with emscripten as asm.js or WebAssembly. All work happens in a WebWorker.
|
||||
* TdClient itself just sends queries to WebWorker, receive updates and results from WebWorker.
|
||||
*
|
||||
* <br><br>
|
||||
* Differences from TDLib API<br>
|
||||
* 1. updateFatalError error:string = Update; <br>
|
||||
* 3. file <..as in td_api..> idb_key:string = File; <br>
|
||||
* 2. setJsLogVerbosityLevel new_verbosity_level:string = Ok;
|
||||
* 3. inputFileBlob blob:<javascript blob> = InputFile;<br>
|
||||
* 4. readFilePart path:string offset:int64 size:int64 = FilePart;<br>
|
||||
* filePart data:blob = FilePart;<br>
|
||||
* 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 the TDLib and manages a filesystem for persistent TDLib data.
|
||||
* TDLib instance is created in a Web Worker, because TDLib needs synchronous access to filesystem and the IndexedDB.
|
||||
* TdClient just sends queries to the Web Worker and receive updates and results from it.
|
||||
* <br>
|
||||
* <br>
|
||||
* Differences from TDLib API:<br>
|
||||
* 1. Added the update <code>updateFatalError error:string = Update;</code> which is sent whenever a TDLib fatal error is encountered.<br>
|
||||
* 2. Added the field <code>idb_key</code> to <code>file</code> object, which contains IndexedDB key in which the file content is stored.<br>
|
||||
* This field is non-empty only for fully downloaded files. IndexedDB database name is chosen during TdClient creation.<br>
|
||||
* 3. Added the method <code>setJsLogVerbosityLevel new_verbosity_level:string = Ok;</code>, which allows to change the verbosity level of tdweb logging.<br>
|
||||
* 4. Added the possibility to use blobs as input files via constructor <code>inputFileBlob blob:<JavaScript blob> = InputFile;</code>.<br>
|
||||
* 5. Added the method <code>readFilePart path:string offset:int64 size:int64 = FilePart;</code> and class <code>filePart data:<JavaScript blob> = FilePart;</code><br>
|
||||
* which can be used on a partially downloaded file to support media streaming.<br>
|
||||
* 6. Methods <code>getStorageStatistics</code>, <code>getStorageStatisticsFast</code>, <code>optimizeStorage</code>, <code>addProxy</code> are not supported.<br>
