    wasmBundlerPlugin({

Options

maxFileSize

Type: Number

Default: 14336 (14kb)

The maximum file size for inline files. If a file exceeds this limit, it will be copied to the destination folder and loaded from a separate file at runtime. If maxFileSize is set to 0 all files will be copied.

Files specified in sync to load synchronously are always inlined, regardless of size.

targetEnv

Type: "browser" | "node" Default: "node"

Configures what code is emitted to instantiate the Wasm (both inline and separate):

"browser" is used in the browser environment, and fetch is used to load the wasm module.

"node" for node environment, use the inline wasm module directly with base64
