Posthog Route Censor Plugin 🚓
This plugin allows you to censor variables from URLs that are passed to PostHog. This is useful because PostHog tracks certain URLs automatically, so if your app contains sensitive data within the URLs (such as sensitive IDs, addresses, etc.), then this offers away to censor that data before it is stored in the PostHog database.
Getting Started
Enable this Plugin for your Posthog Project
- coming soon
Locally
yarn # installs dependencies
yarn build
Plugin Options
The list of properties censored by the plugin can be configured directly from the PostHog UI.
{
"key": "routes",
"name": "JSON list of routes following the React Router route patterns. See package README for more details.",
"type": "attachment",
"hint": "See README for more details and example.",

Routes
To provide routes, attach a JSON file, similar to the example at ./src/assets/exampleRoutes.json
, that matches the Routes type defined in './src/types/index.ts`.
The routes JSON includes an array of all pathnames that you would like to censor. The routes should match the pattern defined by the first parameter of the React Router V6 matchRoutes function, with an extra attribte includes
. includes
should contain a list of variables from the path
pattern that you wish to censor.
Example Routes JSON
./src/assets/exampleRoutes.json
:
[
/**
* This will censor the `driversLicenseId` variable from the URL.
*
* https://example.com/drivers-license/12345 => https://example.com/drivers-license/:driversLicenseId
*/
{
"path": "/drivers-license/:driversLicenseId",
"include": ["driversLicenseId"]
},
/**
* This will censor the `medicalIdNumber` variable from the URL.
*
* https://example.com/medical-id-number/12345 => https://example.com/medical-id-number/:medicalIdNumber
*/
{
"path": "/medical-id-number/:medicalIdNumber",
"include": ["medicalIdNumber"]
},
/**
* This will censor the `secretClubId` variable from the URL, but will not sensor the `categoryId` variable.
*
* https://example.com/secret-clubs/12345/abcde => https://example.com/secret-clubs/12345/:secretClubId
*/
{
"path": "/secret-clubs/:categoryId/:secretClubId",
"include": ["secretClubId"]
}
]
Properties
Note: you probably don't need to change this from the default values.
properties
, set_properties
, and set_once_properties
are a comma separated list of properties that will be censored by this plugin. All properties in these lists should contain either a full URL (ex: "https://www.example.com/super-secret-id/1234") or a pathname (ex: "/super-secret-id/1234"). The default values should already include all properties with URLs that PostHog tracks by default, but more can be added to this list when configuring your plugin if needed.
Caveats:
- Any properties previously defined for a user by
$set_once
cannot be overwritten by this plugin. It can only overwrite$set_once
properties when they are initially set. - The routes JSON must be updated whenever a new route is added to your app.
