Scratch JR for Desktop | Open Source Community Port

Same app, new platform.

To port to the desktop, a small database and filesystem layer was rewritten, as well as access to video and sound.

This was accomplished using

Offline mode

Once installed, this app should not require an internet connection to work.

Deleting stuff (press and hold mouse)

Because this is a tablet app, there is no right click support. In order to delete stuff you need to click
and hold the left mouse button until everything wiggles. When you get a red X, click this to remove
characters and projects.

Where’s the cat?

Sadly, the cat is not allowed to make an official appearance
in our app but has sent along all of his friends. Everything (else) you
know and love about Scratch Jr on the tablet is there.

Getting Started with your Class

Scratch Jr has a set of programming

Where’s the data?

All projects are stored locally on the machine inside of a file (which happens to be a sql lite database.)

Inside your documents/ScratchJR folder, there will be a scratchjr.sqllite file.

Reloading saved projects

For classroom use, sometimes it is handy to pre-configure a set of projects. All of the projects all save into the same Documents/ScratchJR/scratchjr.sqllite file.

To set up projects beforehand, you can make a backup copy of this file.

Here’s how.

• Make starter projects for your class – set up Scratch Jr with the projects you want everyone to use.
• Open up the ScratchJR folder inside of Documents
• Copy the scratchjr.sqllite file to scratchjr.sqllite.restore
• Re-open ScratchJR for desktop.

After completing, there will be a menu option for restoring the projects. This will reset all the projects back
to a clean copy of your projects. This is handy for a shared classroom setting where you don’t wish to
save the work between students.

To port to the desktop, a small database and filesystem layer was rewritten, as well as access to video and sound.This was accomplished using Electron for the app hosting, the original html source of ScratchJR and SQL.js for the project database. Electron is like having your own chrome browser to run one html webpage. And in our case, that webpage is ScratchJR.Once installed, this app should not require an internet connection to work.Because this is a tablet app, there is no right click support.
