Description

Npm and Amber watch seem to hold on to old data.
Changes are not reflected upon refresh of page.

Steps to Reproduce

1. Run amber w
2. make a change to project
3. attempt to refresh the page.

Expected behavior: Content updates to show changes

Actual behavior: No changes rendered (note: terminating amber watch and refreshing the page still renders server info in terminal)

Reproduces how often: 90%

Versions

Amber Version - v0.6.0
Crystal Version - 0.24.1

OS - Gnome version 3.26.2

Additional Information

running with crystal on different port is a way around this for now.

Seems to be related in someway to NPM. I can kill all crystal/amber processes and it still renders code to my browser.
