Like Docker, but for WASM.
You can download binaries directly from the Releases page.
Or you can install it using cargo:
cargo install wacker-daemon
cargo install wacker-cli
Start the wacker daemon:
$ wackerd
[2023-11-22 07:25:31 INFO wackerd] server listening on "/Users/user/.wacker/wacker.sock"
Run a WebAssembly program:
$ wacker run hello.wasm
$ wacker run time.wasm
Where hello.wasm is a simple WASM program that prints out Hello, world! and exits, and time.wasm is a long-running program that constantly prints out the current time.
You can find more WASI program examples at https://github.com/wacker-dev/wasi-examples.
Serve an HTTP WebAssembly program:
$ wacker serve hello_wasi_http.wasm --addr 127.0.0.1:8081
The path can be a local file path or a URL, eg:
$ wacker run https://raw.githubusercontent.com/wacker-dev/wacker/main/wacker/tests/wasm/hello.wasm
List running programs:
$ wacker list
ID PATH STATUS ADDRESS
hello-w0AqXnf hello.wasm Finished
time-xhQVmjU time.wasm Running
hello_wasi_http-luf1vz6 hello_wasi_http.wasm Running 127.0.0.1:8081
Fetch the logs:
$ wacker logs hello-w0AqXnf
Hello, world!
$ wacker logs -f --tail 5 time-xhQVmjU
current time: 2023-11-22 07:42:34
current time: 2023-11-22 07:42:35

And you can also stop/restart/delete the program:
$ wacker stop time-xhQVmjU
$ wacker restart time-xhQVmjU
$ wacker delete/rm time-xhQVmjU
