deno

问题 After created an index.ts and wrote a simple code for listening to port 3000 and printing hello world on the body, I'm also not able to run or get the output from deno's drun module. import { Application, Router } from "https://deno.land/x/denotrain@v0.5.0/mod.ts"; const app = new Application(); const router = new Router(); // Middleware app.use((ctx) => { ctx.cookies["user.session"] = "qwertz"; ctx.cookies["a"] = "123"; ctx.cookies["b"] = "456"; delete ctx.cookies["user.session"]; return; })

问题 Since it is not necessary to have package.json file with deno, how can I as a developer have a similar experience just as we have with npm scripts in package.json ? 回答1: deno install You can create executable, aliased scripts with deno install. It will provide a thin shell/cmd wrapper for the specified main module and CLI arguments. Example: deno install --root . -n serve --allow-read --allow-net https://deno.land/std@0.54.0/http/file_server.ts The result is a serve script, similar to npm

问题 In Deno, to import a TypeScript module, does your own code file have to be TypeScript? Or does Deno auto convert TypeScript to javascript before the module gets imported? I want all my code files to be EcmaScript modules (js or mjs, but not ts). Unlike everyone else these days, I want to avoid using TypeScript in my own code. I dislike the rigidity of static types and Typescript is not part of the EcmaScript standard. EcmaScript alone has all I need to manage big projects. To me, TypeScript

问题 I often find myself typing at least two or three permission options when playing with Deno: deno run --allow-net --allow-read --allow-env app.ts There's a way to escape explicit permissions. 回答1: You can use: --allow-all or the short option -A to allow all permissions. Have in mind that it will include all of the following permissions: --allow-env Allow environment access --allow-hrtime Allow high resolution time measurement --allow-net=<allow-net> Allow network access --allow-plugin Allow

问题 I was running denon, which is like nodemon in node, but I'm getting permission issues even when I've manually specified the relevant flags (specifically --allow-net flag.) How do I run my app with denon so I don't have to keep restarting? 回答1: Without knowing the exact error it's hard to give you the correct answer, but denon is unstable, it has several issues. One of those errors that you might be affecting you is if you're trying to watch a folder that you may not have ownership you'll get:

问题 I want to convert a Node.js project to Deno. Is there any guide available? My current project has lots of NPM files and it's already in TypeScript. Any tips? 回答1: Deno and Node.js APIs are not compatible, of course you will be able to reuse all javascript/typescript code but you'll need to refactor or add polyfills. To ease migration Deno provides a Node Compatibility library, std/node , which still needs a lot of work. Fortunately require is one of the already supported polyfills import {

问题 I have mentioned the dependency in dep.ts file and I want to import the reference in another file. But I am getting the following error. Please help me to resolve. I was following the link as mentioned below. https://deno.land/manual/linking_to_external_code#it-seems-unwieldy-to-import-urls-everywhere My simple code goes here. dep.ts export { log } from "https://deno.land/std/log/mod.ts"; Test3.ts import { log } from "./dep.ts"; export class Test3 { public show() { log.debug("Exploring deno .
