Course Overview
"Full-stack" sounds like four technologies. It is really one question asked four times: where does this piece of information live, who is allowed to change it, how does it travel, and what does the person see while it is travelling.
This course builds a single real application over fourteen chapters. You design the data first, put an API in front of it, secure it, then build the interface that consumes it — in that order, because that is the order in which the decisions actually constrain each other. Nothing is a toy: the app you finish with has accounts, permissions, real data and a live URL.
You need to be comfortable with JavaScript before chapter one. If you are not, the JavaScript course is free and comes first.
What You’ll Learn
✅ Node and npm: JavaScript outside the browser, packages, scripts, environment variables.
✅ Express: routes, middleware, request and response, error handling.
✅ MongoDB and Mongoose: documents, schemas, relationships, queries and indexes.
✅ REST API design: resources, methods, status codes, validation, and versioning.
✅ Authentication: password hashing, JWTs, protected routes, and what belongs on the client.
✅ React: components, state, routing, forms and data fetching against your own API.
✅ Deployment: environment config, CORS, a build, and a running production app.
The Chapters
1 — What full-stack really means. Client, server, database, and where each decision belongs. You can draw your application as three boxes and say what crosses each line.
2 — Node and npm. Running JavaScript on a server, modules, package.json, scripts, .env. You can start a Node project from empty and keep a secret out of your repository.
3 — Express, the first route. Server, routing, request and response, middleware order. You can serve JSON from a URL you invented.
4 — Designing the data. Documents versus rows, embedding versus referencing, what a schema is for. You can model your application’s data and defend the shape.
5 — MongoDB and Mongoose. Connecting, schemas, validation, create-read-update-delete. You can persist and retrieve real records.
6 — Designing the API. Resources, HTTP methods, status codes, consistent responses. You can write down every endpoint your app needs before writing any of them.
7 — Validation and errors. Checking input at the boundary, one error shape, useful messages. Your API refuses bad data and says why, instead of crashing.
8 — Authentication. Registration, bcrypt hashing, JWTs, protected routes. You can build a login where the server, not the browser, decides who gets in.
9 — Authorization and relationships. Ownership, roles, references, populated queries. A user can only touch their own records, and you can prove it.
10 — React fundamentals for this app. Components, props, state, lists, keys. You can render your app’s screens against fixed data.
11 — React talking to your API. fetch, loading and error states, forms, optimistic updates. You can create and edit a record from the interface and see the database change.
12 — Routing and app structure. Pages, protected routes, storing the session, layout. A logged-out visitor cannot reach a logged-in page.
13 — Getting ready for production. CORS, environment config, secrets, a build, basic logging. You can explain why it worked locally and failed everywhere else.
14 — Deploy and keep it alive. Hosting the API, hosting the client, the database in the cloud, and what to check after a deploy. Your app has a URL and a person other than you has used it.
Course Highlights
🔥 One application, fourteen chapters — every chapter changes the same codebase.
🔥 Data and API before interface, because that is the order in which mistakes get expensive.
🔥 Auth done once, properly, rather than a TODO you never come back to.
🔥 Free, including the test and the certificate.
Who Should Enroll?
- Developers comfortable with JavaScript who want the whole stack.
- Freelancers and job seekers who need one substantial project they can walk someone through.
- Anyone who has built a front end and now needs the server behind it.
The Test and Certificate
Fourteen chapters, one paper: HTTP semantics, schema design, middleware, JWTs, React state and the deployment mistakes everyone makes once. Register, take the hall ticket, sit the timed test, and pass to earn a certificate with your name on it.
Sit it now, free: take the practice test for this course. It is scored in your browser and it is a self-assessment, not a proctored exam.
