Publishing your Package
Let's say you have a WebAssembly application, and you would like to publish it to WAPM so more people can use it easily.
You might have a similar project structure:
1
/
2
my_program_wasi.wasm
3
my_other_program_wasi.wasm
4
README.md
5
LICENSE
Copied!
Now, in the root of your project, you can simply run
1
wapm init
Copied!
And it will guide you the process of creating a new
wapm.toml file for your project. At the end, it should have generated a manifest like the following:1
[package]
2
name = "username/my_package"
3
version = "0.1.0"
4
description = "The description of the package"
5
6
[[module]]
7
name = "my_program_wasi"
8
source = "my_program_wasi.wasm"
9
10
[[module]]
11
name = "my_other_program_wasi"
12
source = "my_other_program_wasi.wasm"
Copied!
Now, you will need to:
Creating an account in WAPM
Creating an account in WAPM is very easy, just go to the following url and sign up!
wapm | Sign up
Login from the wapm CLI into your local account
Now that you are registered, you can just run the following command and it will ask for your credentials
1
wapm login
Copied!
Publish the package to WAPM
Now that you have successfully created a
wapm.toml manifest file for your project and have logged in into WAPM, you just need to run one more command!1
wapm publish
Copied!
And you package should now be live in wapm.io 🎉
Commands
Commands (not to be confused with wapm-cli subcommands) are a feature that enables easily executing Wasm code from a WAPM package.
Commands are what allows one to call the
run subcommand, like above when running wapm run cowsay hello wapm!.A command requires a name and module to reference:
1
[[command]]
2
name = "my_cmd"
3
module = "my_program_wasi"
Copied!
Now called
wapm run my_cmd will execute the module defined with the name my_program_wasi. Under the hood, wapm calls wasmer, the WebAssembly server runtime.If you want to learn more about the manifest format, please jump into the next article!
