Once you have the server running and modify the database, and stop the server, it will show this:
Uncaught PermissionDenied: Acceso denegado. (os error 5), open './database.sqlite'
const rid = Deno.openSync(path, { read: true, write, create }).rid;

I don't know why, but it "resolves" when the database.sqlite file is deleted.
Hi,
Thanks for sharing this interesting and article — hope it’s ok if I ask a rather basic question.
I tried adding a flight to the db with a POST
request, like this (from the browser, at localhost:3000):
fetch('http://localhost:3000/flight', {
method: 'POST',
body: {
departure: "Washington DC",
destination: "Los Angeles",
flightDuration: 5.5
}
})
.catch(e => console.log(e))
When I do that, the server crashes with this error:
opine_api/$ deno run --allow-net --allow-write --allow-read app.ts
https:\localhost: 3000
That’s startup, looks good — I can’t the Paris-Madrid flight at /flight
.
But then I try running the fetch above, and this happens:
TypeError: ReadableStream is locked.
