Slap HTTP requests straight into a local SQLite3 database. Fun for debugging!

GPLv3 licensed because if you wanted to pay for something more full-fledged you'd probably be using one of the SaaS services for this, lol.

Request filtering

To facilitate more targeted request logging, the Viper config variable filter supports a github.com/google/cel-go expression that returns a boolean.

For those not familiar with Viper, this means you can configure the CEL filter via any of:

• execution args: --filter 'expression here'
• config file: filter: 'expression here'
• env var: FILTER='expression here'

Supported CEL variables are:

• host - HTTP host header
• path - absolute URL path, including the leading slash
• method - HTTP method
• header - map of HTTP headers
• source_address - IP:port as a string

Due to CEL limitations, all n-dashes are converted to underscores. This is particularly noticable when filtering headers.

Example filters

Only save PATCH requests to localhost:4676.

method == "PATCH" && host == "localhost:4676"

Only save requests with a User-Agent of curl/*.

header.User_Agent.startsWith("curl/")
// alternatively, use RE2 regex
header.User_Agent.matches("^curl/.+")
matches(header.User_Agent, "^curl/.+")

Only save requests from a particular IP address.

source_address.startsWith("9.9.9.9")

For everything else that you can do with CEL, reference the language grammar.
