Image Upload Server

After having spent many hours looking for a simple and actually working image upload solution for Deno, I decided to program and publish this module.

This Deno Module supports the cultmagazine.org.

Usage

Basic

At the moment it is still necessary to git clone this repo because https://deno.com/blog/v1.25#experimental-npm-support is still experimental (I use e.g. npm:express and npm:formidable which are considered “local modules”). Let’s wait for some more magic by Ryan Dahl and Friends before improving the programmer experience even further.

git clone https://github.com/cultfamily-on-github/cult-image-upload-microservice.git
cd cult-image-upload-microservice

… then you can Do things like

// import { ImageUploadServer } from "https://deno.land/x/cult_image_upload_server/mod.ts" // not yet working because e.g. npm:express is seen as a local module
import { ImageUploadServer } from "./mod.ts"

const port = 8048 // you can choose any port where the ImageUploadServer shall serve

ImageUploadServer.getInstance(port).start()

// visit http://localhost:8048 and do the obvious :) enjoy be happy and support the CULT

Advanced

If you want to use an authentication function for specific routes, you can do it as follows:

import { ImageUploadServer } from "./mod.ts"

const port = 8048 // you can choose any port where the ImageUploadServer shall serve

const authenticationMiddlewareFunction = (req, res, next) => {
    console.log(`executing authenticationMiddlewareFunction`)
    const theMeaningOfLife = 42
    if (theMeaningOfLife === 42) {
        next()
    } else {
        console.log("someone might want to update the meaning of life")
    }
}

const activateMiddlewareForSpecificRoutesOptions = [{
    route: "/api/v1/uploadImage",
    middlewareFunction: authenticationMiddlewareFunction
}]

ImageUploadServer.getInstance(port, activateMiddlewareForSpecificRoutesOptions).start()

// visit http://localhost:8048 and do the obvious :) enjoy be happy and support the CULT
