upload file using BusBoy in combination with ExpressJS, NodeJS and TypeScript

We believe adaptation to the latest trends in the coding. Hence, we have been using TypeScript in all our major projects. We love code the the frontend in Angular 2, React and the dynamic backend in NodeJS.

Here’s a small example we have created using TypeScript, NodeJS and ExpressJS to upload a file with BusBoy using Typescript.

Please follow the below steps.

Step 1: Clone repository with the following command.

git clone

Step 2: Go to project directory and run

npm install

Step 3: Now execute. ( npm run grunt command is for compiling the typescript

source code, you can check out gruntfile.js have all the configuration. )

npm run grunt

Step 4: Create images folder inside the dist folder

mkdir dist/images

Step 5: Now run

npm run start

Step 7: Here is the URL for file upload

http://localhost:8080/fileupload and pass multipart form data.

Brief information about Typescript files.

  1. server.ts in src folder -> In this file we export the Server class, this class will configure our express web application, REST API and routes.
  2. route.ts in src/routes/ folder -> This file will export the BaseRoute class, In this class you can define script for all routes which will be required. Method render() will invoke BaseRoute’s child class.
  3. index.ts in src/routes/ folder -> This class extends BaseRoute class, you can define route in create() method.
  4. routes() method in server.ts -> In this method we have created router instance of express.Router() and call the create() method of IndexRoute and passed router as a parameter.

I hope the steps have got the example running in you local machine. We love to share at Third Rock Techkno what we learn with our community.

Happy coding !!!
