Deno

Deno is a JavaScript/TypeScript runtime with secure defaults and a great developer experience. It's built on V8, Rust, and Tokio.
- Secure by default. No file, network, or environment access (unless explicitly enabled).
- Supports TypeScript out of the box.
- Ships a single executable (deno).
- Has built in utilities like a dependency inspector (deno info) and a code formatter (deno fmt).
- Has a set of reviewed (audited) standard modules that are guaranteed to work with Deno.
- Scripts can be bundled into a single javascript file.

While writing string data (example = "121212121212121" -> string of all integer characters) into excel.
while user download and see, the downloaded xl/CSV, the data is shown in exponential format. Is there a way to show the same data. without converting into exponential in this case.

Describe the bug
Currently one user provided AbortSignal
instance can't be used to control multiple Deno std library HTTP servers running at the same time, because under the hood instead of using the addEventListener
method to safely listen for abort
events, onabort
properties are set which overrides previously set handlers.

If you perform C-h f and read the dialog, it can link you to the implementation for that function.
There isn't any technical barrier to do this for JS/TS.
It would be great to have a lint rule to flag when true
or false
is passed to a function.
As a solution the problem of a vague true/false value passed to a function, the "boolean trap", I have a habit of creating a self-documenting constant and using that instead.
Instead of redraw(true)
, I'll define const INLINE = true;
and then use redraw(INLINE);
.
Thanks for considering this

Not sure if this is the correct way to do it, but I wanted to save a cache script I could easily run.
"cache": {
"desc": "Cache versions and update lock file",
"cmd": "deno cache server.ts --lock-write",
"lock": "./lock.json"
}
The result however when running denon cache
is an endless loop instead of just executing it once, looks like this:

Relative URLs in readme markdown starting with ./
should link to files within the package, but incorrectly deno.land renders them as if they are deno.land/x packages.
Here is an example readme with broken relative URLs (the top logo SVG, and various links to package modules):
https://deno.land/x/ruck@v1.0.0
Similar to a past issue (that was apparently fixed) for relative URLs that don't

To reproduce:
- Create a table with a
date
column (for example,"date_of_birth" date not null
) - Make an insert (I'm using
mikro-orm
and passing in"1983-09-12"
) - Select the record and log the model object
Expected: dateOfBirth: '1983-09-12'
as a String
Actual: dateOfBirth: 1983-09-12T00:00:00.000Z
as a Date
When I follow these steps with an actual Postgres
Deno's implementation of the structured clone algorithm is divided into a JS part, and a native part which doesn't have access to
DOMException
. Since serialization errors must be represented by throwing aDataCloneError
DOMException
, the native part throws aTypeError
with the required message, and the JS part [rethrows an
