The manifest (wapm.toml) is optional for using the wapm CLI tool; it manages package dependencies, metadata and commands.

However, a manifest is required to publish to the WAPM registry.

The manifest file contains 4 sections:

[package]

Valid keys are:

• name (string) required

• version (semver version) required: a valid Semantic Versioning version.

• description (string) required

• license (spdx identifier): can be MIT or GPL, for example.

• license-file (path): an override for the license file path used in publishing. Left undefined, the LICENSE file will be implicitly included in the package.

• readme (path)

• repository (url)

• homepage (url)

• wasmer-extra-flags (string): extra arguments to pass via wapm run, for example: "--backend=singlepass")

[dependencies]
