Validates headers related to the Attribution Reporting API.

Interactive form deployed at https://wicg.github.io/attribution-reporting-api/validate-headers.

On requests:

• Attribution-Reporting-Eligible

On responses:

• Attribution-Reporting-Register-OS-Source
• Attribution-Reporting-Register-OS-Trigger
• Attribution-Reporting-Register-Source
• Attribution-Reporting-Register-Trigger

Sources and triggers can also be validated from the command-line:

npm run header -- --help

Examples:

The flexible-event utility accepts comma-separated lists of the number of windows and summary buckets per trigger data. This is essentially an unzipped list of two-tuples, one per trigger data.

npm run flexible-event -- -w 1,2,3 -b 4,5,6

The utility also will parse the source registration JSON to compute the number of windows / summary buckets.

npm run flexible-event -- -f /path/to/source_registration.json

Here is an example which matches the default config for navigation sources:

npm run flexible-event -- -w 3,3,3,3,3,3,3,3 -b 3,3,3,3,3,3,3,3 -m 3 -t navigation
