Type alias ManifestLike

Any type that can be converted into an Extism Manifest.

• object instances that implement Manifest are validated.
• ArrayBuffer instances are converted into Manifests with a single ManifestWasmData member.
• URL instances are fetched and their responses interpreted according to their content-type response header. application/wasm and application/octet-stream items are treated as ManifestWasmData items; application/json and text/json are treated as JSON-encoded Manifests.
• string instances that start with http://, https://, or file:// are treated as URLs.
• string instances that start with { treated as JSON-encoded Manifests.
• All other string instances are treated as ManifestWasmPath.

let manifest = {
  wasm: [{name: 'my-wasm', url: 'http://example.com/path/to/wasm'}],
  config: {
    'greeting': 'hello' // these variables will be available via `extism_get_var` in plugins
  }
}

let manifest = '{"wasm": {"url": "https://example.com"}}'
let manifest = 'path/to/file.wasm'
let manifest = new ArrayBuffer()
Copy

Throws

TypeError when URL parameters don't resolve to a known content-type

Throws

TypeError when the resulting Manifest does not contain a wasm member with valid ManifestWasm items.
