You don't have to explicitly include build folder, because it's already set as the main folder in package.json.

Suggested change

	const {render, Text, Box} = require('../../build');
	const {render, Text, Box} = require('../..');

To keep it explicit, because stdout is not an instance of the process, so subProcess wouldn't be a right name for it.

Suggested change

	const subProcess = childProcess.spawn('ping', ['8.8.8.8']).stdout;
	subProcess.on('data', newOutput => {
	setOutput(newOutput.toString('ascii'));
	});
	const subProcess = childProcess.spawn('ping', ['8.8.8.8']);
	subProcess.stdout.on('data', newOutput => {
	setOutput(newOutput.toString('ascii'));
	});

Suggested change

	<Text>My ping output:</Text>
	<Text>My <Text bold>ping</Text> command output:</Text>

To give it a little more breathing room. It's also probably a good idea to limit the number of lines you can print, to ensure it doesn't fill up the entire terminal window.

Suggested change

	<Text>{output}</Text>
	<Box marginTop={1}>
	<Text>{output}</Text>
	</Box>

To give the whole UI more space.

Suggested change

	<Box flexDirection="column">
	<Box flexDirection="column" padding={1}>
