This page covers building tdweb from source; the separate tdweb guide covers browser integration. emsdk 3.1.1 is the version identified by upstream, not evidence that every current environment has been rebuilt successfully here.
TDLib Web example
This is an example of building TDLib for browsers using Emscripten.
These scripts build TDLib and create an NPM package tdweb.
You need a Unix shell with sed, tar and wget utilities to run the provided scripts.
Building tdweb NPM package
Install the 3.1.1 emsdk, which is known to work. Do not use the system-provided emscripten package, because it contains a too old emsdk version.
Install all TDLib build dependencies described in Building and sed, tar and wget utilities.
Run source ./emsdk_env.sh from emsdk directory to set up the correct build environment.
On macOS, install the coreutilsHomebrew package and replace realpath in scripts with grealpath:
brew install coreutils
sed -i.bak 's/[(]realpath/(grealpath/g' build-tdlib.sh
Run build scripts in the following order:
cd <path to TDLib sources>/example/web
./build-openssl.sh
./build-tdlib.sh
./copy-tdlib.sh
./build-tdweb.sh
The built package is now located in the tdweb directory.
