HTTP Toolkit runs everything possible within the web UI, written as a standard single-page web application. There's a couple of necessary things you can't do in a web application though, especially:
This server is runnable standalone as a CLI using oclif, or can be imported into other modules to be run programmatically. The available interceptors are defined in
src/cert-check-server.tsautomatically checks if a certificate is trusted by a browser client, and downloads or installs (depending on the client) the certificate if not.
Note that the set of interceptors available in HTTP Toolkit depends on both the interceptors available on your server and the interceptors defined in the UI - new interceptors will need to be added to both.
This server is typically used by users via httptoolkit-desktop, which builds the server and web UI into an electron application, and starts & stops the server in the background whenever that app is run. Each time the desktop app is built, a new electron app is created containing the latest release from this repo.
Once the server has installed it automatically updates in the background periodically, pulling new releases from the github releases of this repo.
If you want to add new interceptors, change/fix existing interceptor behaviour (but not their UI) or reconfigure how the underlying proxy server is set up, then you're in the right place :+1:.
To get started:
https://app.httptoolkit.techin a Chromium-based browser, or start and use a local UI by:
npm run start:webthere to start the UI without its own server.
http://local.httptoolkit.tech:8080in a Chromium-based browser
A few tips:
trueat the top of
src/api-server.tswill give you a GraphQL playground on http://localhost:45457/.
src/interceptors/index.ts. They will also need to be added to the UI.
