Getting Started

This guide will introduce the wapm tool and show a few common workflows. The WAPM client can install packages, manage WebAssembly dependencies, and expose WebAssembly behavior with commands.

Install WAPM

WAPM comes bundled with Wasmer, so you just need to install Wasmer in your system to have the wapm CLI!

Basic Usage

With the tools installed, one can easily start using universal Wasm binaries by using the install command of wapm CLI:

wapm install cowsay

Installing a package creates a local package directory called wapm_packages where all packages are installed.

Did you know ...?

A WAPM package can be installed globally by adding the -g flag. Eg:wapm install -g cowsay

While in a directory with WAPM packages, one may execute them with the run command:

wapm run cowsay hello wapm!
< hello wapm! >
-------------
\ ^__^
\ (oo)\_______
(__)\ )\/\
||----w |

Great! You used a WAPM package in your system... now let's try to create our own package and publish it to WAPM so other users can use it

When executing WAPM, you can also customize the WebAssembly runtime used under the hood.

For example, if you want to use wasmer-js as the runtime, you can do:

WAPM_RUNTIME=wasmer-js wapm run cowsay hello wapm!
