What I learned from this project

Milestones

My first native (read: .exe) app of significant complexity
My first app that's used on a regular, daily basis, by a commercial organisation, for profit.

Frameworks and libraries

Rudimentary Vue.js (seems like I've only scratched the surface: haven't used components, only one big global object)
Rudimentary Electron (main and renderer process, but didn't use the main process much)
localForage (this is the first time I've had to store data locally)
vex (non-blocking dialog boxes)

Build tools

Using webpack to build multiple source files
How to create and import modules

Software engineering

Packaging and releasing a piece of software (I used Github's releases function. This is also the first time I have created a JS Windows executable. For form-emailer I believe I used cxFreeze, for Python.)

Things I already knew but got to practice

HTML5 canvas
Writing clean code and refactoring
Splitting up code into different files
Working with promises
Working with the file system

My thoughts

I have spent about 100 hours on this project at this point; it should be (more or less) feature complete
I really enjoy the idea of building software that helps someone streamline their workflow
It's a good feeling to know that your software is being used by users
I also like the feeling of being able to create a piece of software all the way from ideation to production; it gives me a sense of accomplishment
