| # npmTimeMachine | |
| # Quickly get package versions where they would have been on a certain date | |
| # Can be useful for getting out of dependency hell by slowly working your way forward in time | |
| # as if you had stayed up to date in the first place. | |
| # | |
| # The script will run and find the appropriate package versions based on public npm publish data | |
| # | |
| # Usage: | |
| # Go to the directory with the package.json and run | |
| # `npmTimeMachine <date>` | |
| # After running it will output <date>_dependencies.json | |
| # Check through this file and then copy into your package.json | |
| # Sweet salvation from the dependency hell :) | |
