Access local development server from phone for testing

[jimtyhurst]

Expected Behavior

As a developer, I want to be able to see how my local development environment looks on different devices, such as large computer screen, tablet-size, and phone.

Actual Behavior

When I run the dev server, npm run develop, I can only access the website from `http://localhost:8000'.

Analysis

• This was a known limitation of Gatsby. See Testing Site with Gatsby Develop from Local LAN, which is supposed to be fixed by Ensure publicPath is always relative for gatsby develop.
• I made the suggested change to package.json, which fixed the problem for me in this environment:
  • macOS 11.5.2
  • running the dev server in zsh with npm run develop
  • Gatsby version: 3.14.0
  • Gatsby CLI version: 3.10.0
