Dream's first several examples make up a tutorial. Each example is a complete project with a helpful README, and plenty of links to next steps and documentation. You can begin at 1-hello, or look in the list below and jump to whatever interests you!

1-hello — the simplest Dream server responds to every request with the same friendly message.
2-middleware — adds the first Dream middleware: the logger.
3-router — different handlers for different paths.
4-counter — the first custom middleware!
5-promise — introduces Lwt, the promise library used by Dream.
6-echo — reads request bodies.
7-template — renders responses from inline HTML templates and guards against XSS.
8-debug — includes detailed information about errors in responses.
9-error — customize all error responses in one place.
a-log — writing messages to Dream's log.
b-session — associates state with client sessions.
c-cookie — sets custom cookies.
d-form — reading forms and CSRF prevention.
e-json — sending and receiving JSON securely.
f-static
g-upload
h-sql — finally CRUD!
i-graphql
j-stream
k-websocket
k-https

That's it for the tutorial!

Reason

There are several examples showing Dream with Reason syntax.

Examples

The rest of the examples cover additional topics in a more-standalone fashion. The goal of the examples is to (eventually) cover the great majority of real-world HTTP usage, so that they make up a good survey. Please open an issue if something is missing!

w-long-polling — asynchronous communication without WebSockets.
w-query — reading URL query parameters.
w-server-sent-events — the server side of JavaScript EventSource.
w-site-prefix — a Web app running not at /.
w-template-stream — writing templates asynchronously, one chunk at a time.
