无法在 Deno 中加载依赖的 txt 文件

Question

I'm making simple package that edits and provides data, saved in txt file.
Since I can't import non-script files(JSON, txt, etc..), I'm using Deno.open() .

sample.txt (In package)

Hello, World!

mod.ts (In package)

const decoder = new TextDecoder("utf-8")

const f = await Deno.open("sample.txt")
export default decoder.decode(await Deno.readAll(f)) // Hello, World!
f.close()

Package runs fine alone, but make error when it is used in other directory.
test.ts (Local file, loads the package in different directory)

import file from "https://raw.githubusercontent.com/gnlow/deno-file-test/master/mod.ts"

console.log(file)

error:

$ deno -V
deno 1.2.0
$ deno run --allow-read test.ts
Download https://raw.githubusercontent.com/gnlow/deno-file-test/master/mod.ts
Compile file:///var/task/__$deno$eval.ts
error: Uncaught NotFound: No such file or directory (os error 2)

    at async Object.open ($deno$/files.ts:37:15)
    at async https://raw.githubusercontent.com/gnlow/deno-file-test/master/mod.ts:3:11

It seems like deno downloads script files only. (generated file image)
I just want to make deno load non-script data files too.
How can I fix this?

Your code works fine, it's important to check the error:

error: Uncaught NotFound: No such file or directory (os error 2)

It's telling you that "sample.txt" does not exist on the current directory. Make sure you're executing Deno from the directory where the file is present.

Aside from that for reading text files you can use Deno.readTextFile instead

export default await Deno.readTextFile("./sample.txt") // Hello, World!

---

Your code expects sample.txt to be on your filesystem, but you're trying to read sample.txt from the github repository, the only solution would be to perform an HTTP request to fetch that file, instead of using Deno filesystem APIs.

But in that case, you won't be able to write to it. For your use case, you should work with local files, so you'll need to create the file if it doesn't exist if you're going to write to it.
