error: Uncaught TypeError: Cannot set property 'dayjs' of undefined

[remdragon]

I'm just trying to get started using dayjs using deno 1.9.0. I've downloaded dayjs 1.10.4 using the link the instructions gave me.

Here is my test file calendar.js:

//import * as dayjs from "https://cdn.jsdelivr.net/npm/[email protected]/dayjs.min.js"
import * as dayjs from "./dayjs.js"

let now = dayjs()
console.log ( now )

And here's what I get when I run "deno run calendar.js":

error: Uncaught TypeError: Cannot set property 'dayjs' of undefined
    at file:///[SNIP]/testing/dayjs.js:1:143
    at file:///[SNIP]/testing/dayjs.js:1:148

Unfortunately since dayjs has been minified, I don't know how to begin to troubleshoot this even further, especially since this is my first attempt to use the library. Am I importing it or doing something else wrong?

Thank you for the suggestion, but I still can't get it to work:

import dayjs from "dayjs" error: relative import path "dayjs" not prefixed with / or ./ or ../ Imported from "file:///[SNIP]/calendar.js"

import dayjs from "./dayjs.js" error: Uncaught SyntaxError: The requested module './dayjs.js' does not provide an export named 'default'

import dayjs from "https://cdn.jsdelivr.net/npm/[email protected]/dayjs.min.js" error: Uncaught SyntaxError: The requested module 'https://cdn.jsdelivr.net/npm/[email protected]/dayjs.min.js' does not provide an export named 'default'

@iamkun Any updates to this issue? Even i am getting the same errors when using typescript.

@remdragon Did you end up finding any solution to this?

[remdragon]

I did not. I ended up developing my own lightweight date management object.

There are three hard problems in computer science: naming things, and off-by-one errors.

You can import it using: import dayjs from "https://cdn.skypack.dev/dayjs"; and you can even import plugins like this:

import timezone from "https://cdn.skypack.dev/dayjs/plugin/timezone";
import utc from "https://cdn.skypack.dev/dayjs/plugin/utc";

Perhaps the README.md file could be updated with a Deno section with small guides as how to use dayjs in Deno.

@shotrifork Above is not working with recent version. Getting this error - cdn.skypack.dev/error/build:[email protected]

This works (in Deno repl):

> import dayjs from "https://esm.sh/[email protected]";
undefined
> dayjs('2018-08-08')
u {
  "$L": "en",
  "$d": 2018-08-08T04:00:00.000Z,
  "$x": {},
  "$y": 2018,
  "$M": 7,
  "$D": 8,
  "$W": 3,
  "$H": 0,
  "$m": 0,
  "$s": 0,
  "$ms": 0
}

You can also use skypack to import dayjs:

import dayjs from "https://cdn.skypack.dev/[email protected]?dts"
