Classes

c
WebAssembly.CompileError

The WebAssembly.CompileError object indicates an error during WebAssembly decoding or validation.

c
WebAssembly.Global

A WebAssembly.Global object represents a global variable instance, accessible from both JavaScript and importable/exportable across one or more WebAssembly.Module instances. This allows dynamic linking of multiple modules.

c
WebAssembly.Instance

A WebAssembly.Instance object is a stateful, executable instance of a WebAssembly.Module. Instance objects contain all the Exported WebAssembly functions that allow calling into WebAssembly code from JavaScript.

c
WebAssembly.LinkError

The WebAssembly.LinkError object indicates an error during module instantiation (besides traps from the start function).

c
WebAssembly.Memory

The WebAssembly.Memory object is a resizable ArrayBuffer or SharedArrayBuffer that holds the raw bytes of memory accessed by a WebAssembly Instance.

c
WebAssembly.Module

A WebAssembly.Module object contains stateless WebAssembly code that has already been compiled by the browser — this can be efficiently shared with Workers, and instantiated multiple times.

c
WebAssembly.RuntimeError

The WebAssembly.RuntimeError object is the error type that is thrown whenever WebAssembly specifies a trap.

c
WebAssembly.Table

The WebAssembly.Table() object is a JavaScript wrapper object — an array-like structure representing a WebAssembly Table, which stores function references. A table created by JavaScript or in WebAssembly code will be accessible and mutable from both JavaScript and WebAssembly.

Functions

f
WebAssembly.compile

The WebAssembly.compile() function compiles WebAssembly binary code into a WebAssembly.Module object. This function is useful if it is necessary to compile a module before it can be instantiated (otherwise, the WebAssembly.instantiate() function should be used).

f
WebAssembly.compileStreaming

The WebAssembly.compileStreaming() function compiles a WebAssembly.Module directly from a streamed underlying source. This function is useful if it is necessary to a compile a module before it can be instantiated (otherwise, the WebAssembly.instantiateStreaming() function should be used).

f
WebAssembly.instantiate

The WebAssembly.instantiate() function allows you to compile and instantiate WebAssembly code.

f
WebAssembly.instantiateStreaming

The WebAssembly.instantiateStreaming() function compiles and instantiates a WebAssembly module directly from a streamed underlying source. This is the most efficient, optimized way to load wasm code.

f
WebAssembly.validate

The WebAssembly.validate() function validates a given typed array of WebAssembly binary code, returning whether the bytes form a valid wasm module (true) or not (false).

Interfaces

I
WebAssembly.GlobalDescriptor

The GlobalDescriptor describes the options you can pass to new WebAssembly.Global().

I
WebAssembly.MemoryDescriptor

The MemoryDescriptor describes the options you can pass to new WebAssembly.Memory().

I
WebAssembly.ModuleExportDescriptor

A ModuleExportDescriptor is the description of a declared export in a WebAssembly.Module.

I
WebAssembly.ModuleImportDescriptor

A ModuleImportDescriptor is the description of a declared import in a WebAssembly.Module.

I
WebAssembly.TableDescriptor

The TableDescriptor describes the options you can pass to new WebAssembly.Table().

I
WebAssembly.WebAssemblyInstantiatedSource

The value returned from WebAssembly.instantiate.
