Before you can compile and run the generated API client, you need to make sure the generated source files are part of a project with the required dependencies. Your project must have a reference to theabstraction package. Additionally, you must either use the Kiota default implementations or pro...
Addons are separate modules that extend the Terminal by building on the xterm.js API. To use an addon, you first need to install it in your project: npm i -S @xterm/addon-web-links Then import the addon, instantiate it and call Terminal.loadAddon: import { Terminal } from '@xterm...
