| # And here's the second place - this runs after we have both the current and | |
| # base branch bundle stats, and will compare them to determine what changed. | |
| # There are two configurable arguments that come from package.json: | |
| # | |
| # - budget: optional, set a budget (bytes) against which size changes are measured | |
| # it's set to 350kb here by default, as informed by the following piece: | |
| # https://infrequently.org/2021/03/the-performance-inequality-gap/ | |
| # | |
| # - red-status-percentage: sets the percent size increase where you get a red | |
| # status indicator, defaults to 20% | |
| # | |
| # Either of these arguments can be changed or removed by editing the `nextBundleAnalysis` | |
| # entry in your package.json file. | |
