Best way for offline development

I'm interested in the communities workflows for development, especially on the Bangle.

Mine is as follows on Arch Linux:

• Starting a local environment with the start script.
  
• Checkout a branch
  
• Open tabs for localhost:4000 and localhost:4001 in chromium.
  
• Install app from local apploader on Bangle
  
• Files to be modified are loaded into the web IDE and edited there or in VSCodium depending on anticipated amount of changes
  
• Upload and debugging in web IDE
  
  

Gotchas:

• I link BangleApps/modules and EspruinoDocs/modules to EspruinoWebIDE/[b|e]mod dirs and set http://localhost:4001/bmod|http://localhost:4001/emod as module dirs in the web IDE. Otherwise CORS prevents me from loading modules.
  
  

I have played around with using the CLI tools for upload with the options for watching files which works fine but I always come back to the browser based method since it it a bit more finicky on the command line.

What are your top tips on developing offline?

Script for starting the environment:

export PATH="$(gem env | grep USER | tr -s ' ' | rev | cut -d ' ' -f 1 | rev)/bin:$PATH"

gem install jekyll jekyll-theme-slate
cd BangleApps
jekyll serve --port 4000 &
cd ..
cd EspruinoWebIDE
jekyll serve --port 4001 &
