The publish
and pack
commands interact with the pkg directory that's
created when you run wasm-pack init
. The pack
command creates a tarball
from the pkg directory and the publish
command creates a tarball from the
pkg directory and publishes it to the NPM registry.
Underneath, these commands use npm pack
and npm publish
. You can read
more about these in the NPM documentation:
Both these commands take the path to the pkg directory as the first argument. You can either set the argument directly to the pkg directory or to the parent of the pkg directory:
$ wasm-pack pack myproject/pkg
| 🎒 packed up your package!
$ wasm-pack pack myproject
| 🎒 packed up your package!
If you try to call pack
or publish
on another directory, you get an error:
$ wasm-pack pack myproject/src/
Unable to find the pkg directory at path 'myproject/src/', or in a child directory of 'myproject/src/'
If you don't set a path, they use the current directory as the path.
