Wasmer-JS CLI

The Wasmer-JS command line interface (CLI) uses a modern Javascript Workflow, which depends on Node.js.

Install Wasmer-JS CLI

To install the Wasmer-JS CLI globally on your system, run the following command:

$ npm install -g @wasmer/cli

The Wasmer-JS CLI tool should now be installed. To test it, run the command wasmer-js --help and you should see output similar to the following:
