| <p>The WebAssembly core specification allows an implementation to define limits on the syntactic structure of the module. |
| While each embedding of WebAssembly may choose to define its own limits, for predictability the standard WebAssembly JavaScript Interface described in this document defines the following exact limits. |
| An implementation must reject a module that exceeds one of the following limits with a <code class="idl"><a data-link-type="idl" href="#exceptiondef-compileerror" id="ref-for-exceptiondef-compileerror③">CompileError</a></code>: |
| In practice, an implementation may run out of resources for valid modules below these limits.</p> |
| <ul> |
| <li>The maximum size of a module is 1,073,741,824 bytes (1 GiB). |
| <li>The maximum number of types defined in the types section is 1,000,000. |
| <li>The maximum number of functions defined in a module is 1,000,000. |
| <li>The maximum number of imports declared in a module is 100,000. |
| <li>The maximum number of exports declared in a module is 100,000. |
| <li>The maximum number of globals defined in a module is 1,000,000. |
| <li>The maximum number of tags defined in a module is 1,000,000. |
| <li>The maximum number of data segments defined in a module is 100,000. |
| <li>The maximum number of tables, including declared or imported tables, is 100,000. |
| <li>The maximum size of a table is 10,000,000. |
| <li>The maximum number of table entries in any table initialization is 10,000,000. |
| <li>The maximum number of memories, including declared or imported memories, is 1. |
| <li>The maximum number of parameters to any function or block is 1,000. |
| <li>The maximum number of return values for any function or block is 1,000. |
| <li>The maximum size of a function body, including locals declarations, is 7,654,321 bytes. |
| <li>The maximum number of locals declared in a function, including implicitly declared as parameters, is 50,000. |
| </ul> |
| <p>An implementation must throw a <code class="idl"><a data-link-type="idl" href="#exceptiondef-runtimeerror" id="ref-for-exceptiondef-runtimeerror③">RuntimeError</a></code> if one of the following limits is exceeded during runtime: |
| In practice, an implementation may run out of resources for valid modules below these limits.</p> |
| <ul> |
| <li>The maximum size of a table is 10,000,000. |
| <li>The maximum number of pages of a memory is 65,536. |

| <p>This document defines a host environment for WebAssembly. It enables a WebAssembly instance to <a data-link-type="dfn" href="https://webassembly.github.io/exception-handling/core/syntax/modules.html#syntax-import" id="ref-for-syntax-import">import</a> JavaScript objects and functions from an <a data-link-type="dfn" href="#read-the-imports" id="ref-for-read-the-imports③">import object</a>, but otherwise provides no access to the embedding environment. Thus a WebAssembly instance is bound to the same constraints as JavaScript.</p> |
