Creating Rust Functions in Node.js with SSVM and Docker

I recently came across SSVM with which we can easily create an app with Rust functions. I followed these steps for creating the application:

1. Creating the development environment with Docker

Get the code

$ git clone https://github.com/second-state/ssvm-nodejs-starter
$ cd ssvm-nodejs-starter

Run Docker container

$ docker pull secondstate/ssvm-nodejs-starter:v1
$ docker run -p 8080:8080 --rm -it -v $(pwd):/app secondstate/ssvm-nodejs-starter:v1
(docker) $ cd /app

2. Create an application

Copy the example application

https://github.com/second-state/wasm-learning/tree/master/nodejs/quadratic

Replace files in the sample application and build

$ ssvmup build
$ npm install express # The application requires the Express framework in Node.js
$ node node/server.js

3. Run application in the browser and check

From the web browser, go to http://localhost:8080/ to access this application.
