proxy
This package contains the code for Cypress's HTTP interception proxy.
HTTP interception
./lib/http contains the code that intercepts HTTP requests. The bulk of the proxy's behavior is in three files:
request-middleware.tscontains code that manipulates HTTP requests from the browserresponse-middleware.tscontains code that manipulates HTTP responses to the browsererror-middleware.tshandles errors that occur in the request/response cycle
Building
Note: you should not ever need to build the .js files manually. @packages/ts provides require-time transpilation when in development.
yarn workspace @packages/proxy build-prod
Testing
Tests are located in ./test
To run tests:
yarn workspace @packages/proxy test
Additionally, the server package contains tests that use the proxy.
