• Parse .d.ts and create alias for them
  • https://deno.land/std/manual.md

Patterns

• Compiler hint

// @deno-types="./vendor/https/deno.land/std/foo/bar.d.ts"
import * as bar from "./bar.js";

• Triple-slash reference in .js

/// <reference types="./vendor/https/deno.land/std/foo/bar.d.ts" />
export const bar = "bar";

Not sure if something like this is already supported:

{
  "modules": [
    {
      "protocol": "https",
      "path": "deno.land/std",
      "version": "v0.51.0",
      "files": [
        "/http/server.ts"
      ],
      "alias": "server.ts"
    }
  ]
}

import { serve } from './vendor/server.ts"

• dem should create alias in the format of deno fmt default.
• Apply deno fmt to created file.

Perhaps I am misunderstanding dem, but it seems dem add should be files in vendor? But I am not seeing this happening. Thus far, only dem alias does anything to vendor/ .

Using dem 0.9.9:

1. dem init
   sucessfully initialized dem.json
2. jq . dem.json

{
  "modules": [],
  "aliases": {}
}

3. dem add https://deno.land/x/[email protected]
   successfully added new module: https://deno.land/x/dejs, version: 0.9.3
4. jq .modules dem.json

[
  {
    "protocol": "https",
    "path": "deno.land/x/dejs",
    "version": "0.9.3",
    "files": []
  }
]

But, there is no vendor directory (if I create vendor/ beforehand, nothing is placed inside of it).

try non- esm.sh typescript module

• This module is using old version of TypeScript to parse import section
  • This is used for dem ensure / dem prune
• Add ability to patch TypeScript automatically.

Add document to describe how to release new version of dem.

• fetch target script
• check if it has default export
• add export { default } from xxx

When i use dem ensure for this project and I started the code. I got Uncaught SyntaxError: The requested module './vendor/https/jspm.dev/typescript/lib/typescript.js' does not provide an export named 'default'

So I looked the code and the hasDefaultExport function return false even if a module a export default. I rewrite the code to get working but that's my first step with typescript and I think my code could be better.

Here is the full function

export function hasDefaultExport(body: string): boolean {
  const sourceFile = ts.createSourceFile("", body, ts.ScriptTarget.ES2020);
  let hasDefault = false;
  sourceFile.forEachChild((node: ts.Node) => {
    if(ts.isExportDeclaration(node)){
      const exportClause: ts.NamedExports = node.exportClause as ts.NamedExports;
      if(exportClause !== undefined){
        hasDefault = hasDefault || (exportClause.elements[0].name.escapedText as string === 'default');
      }
    }
  });
  return hasDefault;
}

Hello, thank you for the module!

I run into a problem when run dem on deno v0.29.0 like this:

$ dem update https://deno.land/[email protected]
sub command https://deno.land/[email protected] does not exist.

I think this is because Deno.args now does not include script name. (denoland/deno#3628)

Would you have a plan to support deno v0.29.0 or above?

Thank you.
