AssemblyScript-template

An AssemblyScript template with support for many environments

This template is all you need to get started in AssemblyScript. It allows you to write a library in AssemblyScript, and use it in various environments.

• The wasm library is in ./src/wasm/.
  This is the AssemblyScript file that exports the functions for your library.
• The browser app is in ./src/browser/. It sets up a simple form to get input from the user and passes it to the wasm.
• The node wrappers are in ./src/node.
  The lib.ts file is a library file, and the cli.ts file is meant to be used as a Node bin.
• The wasi wrappers are in ./src/wasi folder.

Note: The AssemblyScript files have a .as.ts or .as extension, and the TypeScript files have a .ts extension.
