shell-command-builder

Construct and execute shell commands

Install:

yarn add shell-command-builder
# OR
npm install shell-command-builder

Require or import the module:

const { CommandBuilder, run, interactive } = require("shell-command-builder");
// OR 
import { CommandBuilder, run, interactive } from "shell-command-builder";

Build shell commands with arguments:

const command = new CommandBuilder("foo", [
  "file.text",
  "--flag-1",
  "--flag-2",
  "-a",
]); //=> foo file.text --flag-1 --flag-2 -a

Convert command to a string:

String(command);
command.toString();
`command = ${command}`;

Use fluent API to add args/flags after initial command is created:

const command = new CommandBuilder("foo");
command.arg("--hello");
console.log(command); //=> foo --hello

Pass in a truthy/falsy condition to optionally add args/flags:

const command = new CommandBuilder("foo");
const options = {
  watch: true,
  quiet: false,
};
command.arg("--watch", options.watch); // added
command.arg("--quiet", options.quiet); // not added
console.log(command); //=> foo --watch

Run commands:

const command = new CommandBuilder("echo 'hello, world!'");
const { stdout } = await command.run(); //=> hello, world!
// OR
const { stdout } = await run(command); //=> hello, world!
// OR
await command.interactive(); //=[shell]=> hello, world!
// OR
await interactive(command); //=[shell]=> hello, world!
