A simple automation tool I made for a client to merge two image files of same size and returns combined image file.
App url: /autogen/:filename accepts a parameter of a filename (combination of two files required). From that parameter, it takes the two image files from two different sources, one is downloaded from remote source and the other is taken locally in the project. Then creates the combined image file and returned as output.
Clone the project and run npm install to install dependencies. Run node app.js to start the app.
