3. If you can build a website,
you can build a desktop app.

4. What is
Electron is a framework for creating
native applications with web
technologies like JavaScript, HTML, and
CSS. It takes care of the hard parts so
you can focus on the core of your
application.

5. Why do we need desktop apps?
⬡ Secure
⬡ Professional level applications
∙ Ex: Photoshop, after effects
⬡ We need to use hardware local
resources
∙ Ex: Edit video
⬡ Novice users

6. Architecture
⬡ Based on Chromium's multi-
process architecture
⬡ An Electron app always has
one main process, but never
more.
⬡ Electron uses Chromium for
displaying web pages
⬡ Each web page in Electron
runs in its own process 6

Pros and cons

21. Pros
⬡ Electron apps are similar to web apps
⬡ Focus on the core part - Electron deal with the hard
part
⬡ Use Chromium APIs - Debugger, Storages, hot
reloading and developer tools
⬡ Node APIs - fs, http, process, commands, etc
⬡ Others features - crash report, auto update, native
features and notifications and windows installers
⬡ No browser compatibility issues
21

22. Cons
⬡ JavaScript - Poor performance
⬡ Size and memory (Chrome + NodeJS)
⬡ Cross-platform build? If your app has
native dependencies, it can be compiled
only on the target platform

Transition headline
Let’s start with the first set of slides

26. This is a slide title
⬡ Here you have a list of items
⬡ And some text
⬡ But remember not to overload your
slides with content
Your audience will listen to you or read the
content, but won’t do both.
26

27. Big
concept
Bring the attention of your
audience over a key concept
using icons or illustrations

fresh snow, the color

combination of all the
colors of the visible

You can also split your content
Black

absorption of light.
28

butter and ripe
lemons. In the

conveyed with just a single
still image, namely making it
possible to absorb large
amounts of data quickly.
