Image automation for content creators

aka I'm to lazy to create images for my blog posts

What is Stencilbot

and why I'm even doing this?

Images drive engagement, some studies show 313% increase (source https://adespresso.com/blog/23-strategies-increase-twitter-engagement)

Tweets from businesses that contain images are 34% more likely to get retweeted than tweets from businesses with no image at all. (source https://blog.hubspot.com/marketing/twitter-statistics )

https://business.twitter.com/en/blog/do-dont-twitter-images.html - create templates

I am lazy and full of imposter syndrome and will take lack of preview image as an excuse not to write a blog post

How it started?

Why it failed?

  • No frontend, i.e. no customer engagement
  • 20$/month 

How it's going?

Address failures

Make it cheap

  1. Serverless
  2. Stateless
  3. Cachable

Make it engaging

  1. Visual editor
  2. Easy to modify

Demo time ⏰

Technicalities

AbstractRenderer (canvas)

BrowserRenderer

(HTMLCanvas)

ServerRenderer

(NodeCanvas)

abstract loadImage(uri: string): Promise<CanvasImageSource>
abstract getLayerCanvas(layer: Layer): HTMLCanvasElement

node-canvas native bindings

  1. Does not work out-of-the-box on AWS Lambda
  2. Container images FTW! (or not)

Lessons learned

  1. Editors are tricky
  2. Native bindings on Lambda are tricky
  3. Query params API is powerful
