![]() Fixes #6259. Adds the location for v8 syntax errors to the message (`message += " at {location}"`) when rethrowing them for dynamic imports. Discussing with @bartlomieju on discord I proposed just preserving v8's error and not reconstructing it, allowing the standard stack trace to just point to the syntax error instead of the dynamic import. But on further thought this way has parity with SWC's syntax errors + has the advantage of showing both the syntax error and dynamic import location. ```ts // temp.js await import("./temp2.js"); // temp2.js function foo() { await Promise.resolve(); } // Before: // error: Uncaught (in promise) SyntaxError: Unexpected reserved word // await import("./temp2.js"); // ^ // at async file:///.../temp.js:1:1 // After: // error: Uncaught (in promise) SyntaxError: Unexpected reserved word at file:///.../temp2.js:2:3 // await import("./temp2.js"); // ^ // at async file:///.../temp.js:1:1 ``` |

Getting Started
Try running a simple program:
deno run https://deno.land/std/examples/welcome.ts
Or a more complex one:
const listener = Deno.listen({ port: 8000 });
console.log("http://localhost:8000/");
for await (const conn of listener) {
serve(conn);
}
async function serve(conn: Deno.Conn) {
for await (const { respondWith } of Deno.serveHttp(conn)) {
respondWith(new Response("Hello world"));
}
}
You can find a deeper introduction, examples, and environment setup guides in the manual.
The complete API reference is available at the runtime documentation.
