WASM General Purpose Bus

The WASM Genernal Purpose Bus implements a standard syscall interface for WebAssembly libraries and executables to use to invoke and receive calls between WASM modules and/or operating system functions.

Currently the WASM Bus is supported by the following runtimes:

• Tokera Terminal (https://tokera.sh/)

Functionality supported by this BUS includes

• Web Socket connections
• HTTP and HTTPS calls
• Spawning sub-processes
• Thread sleeping and timeouts
• Asynchronous Runtime Engine

TODO

• Spawning threads
• Multi-threaded Runtime Engine
• Universal Logging
• Server side invocation of WASM modules
• Client side invocation of WASM modules

Backend Implementations

In order to implment this BUS on your runtime one needs to chain to the ABI exposed in this library and implement the functions.

For a reference implementation see below:

Testing

You can test your WASI program by uploading it to wapm.io and then heading over to the Tokera Shell
