A React hello world needs three pieces: Babel to translate JSX, webpack to bundle the entry file, and a dev server to serve the result. This manual setup was demonstrated in a 2019 Portuguese-language tutorial by Gustavo Dev Doido on the Dev Doido channel, and the underlying tools still work the same way in 2026.
Turning a walkthrough into a written reference
A video walkthrough is fast to watch once and slow to consult later. Writing down the config files, the exact package names and the dev server port turns a one-time lesson into a reference you can reopen when a build breaks. The goal is not a transcript but a lookup table: every command, version and file path captured where search can find it.
That is the shortest path from tutorial to documentation: the same steps, the same order, with the commands written where you can search them. A written reference also survives the video: when a package moves on, you can diff the old instructions against the new ones instead of scrubbing a timeline.
What a reference needs that a video does not:
- The exact package names and versions installed, not just the folder that appeared.
- The full contents of each config file at the moment it worked.
- The dev server port and the URL it prints on start.
- The error messages you hit, and the fix for each one.

Checking setup instructions before you trust them
Drafts start from a spoken walkthrough, so verify the specifics against the primary docs before publishing. For Babel, confirm the preset names in the Babel presets documentation; for bundling, check the webpack configuration guide; and for the project scaffolding itself, the Create React App getting-started page is the usual starting point. Where the video and the docs disagree, the docs win and the video becomes a note.
Frequently asked questions
- Why write the steps down if the video already exists? Video is linear and unsearchable; a written page lets you jump to the config line that broke.
- Should the article include the full config files? Yes. A reference that omits the file contents sends you back to the video.
- How much editing does a generated draft need? Enough to check package names, versions and ports against the official docs before publishing.
- Where should the source video be linked? Keep it at the end, so readers can watch the original after following the written steps.
