Expose the interception infrastructure that already existed internally but was
private, so embedders can intercept, observe, mock, or block JS fetch()/XHR
without forking or unsafe casts.
On obscura::Page:
- add_preload_script: inject JS before any page <script> (CDP
Page.addScriptToEvaluateOnNewDocument). The field already ran the scripts;
this only adds the method.
- enable_interception: returns a receiver for every JS fetch()/XHR request;
resolve each through its resolver with InterceptResolution::{Continue,
Fulfill, Fail} to pass, mock, or block (CDP Fetch.enable equivalent).
- on_request / on_response: passive callbacks. on_response is the main path for
capturing API response payloads from SPAs.
on_request/on_response previously fired only for navigation; op_fetch_url now
invokes them for JS fetch()/XHR too (both reqwest and stealth paths), gated on
a non-empty callback vector so the common no-callback case pays nothing.
Re-export InterceptedRequest, InterceptResolution, RequestInfo, ResourceType,
RequestCallback, ResponseCallback, Response from the obscura crate.
Integration test tests/interception.rs exercises all three against a local echo
server.
* feat(api): add obscura-api crate with Browser + Page API
Adds a Rust library crate exposing Obscura as a programmable browser:
- Browser: build with config (proxy, stealth, UA, storage_dir)
- Page: goto, url, evaluate, content
- BrowserBuilder with fluent API
- examples/basic.rs
Part of #169
* feat(api): add Element API + CookieStore + wait_for_selector
- Element: text(), attribute(), click() via JS evaluation
- CookieStore: set/get_all/get_for_url/save_to_file/load_from_file
- Page::wait_for_selector with 100ms polling
- Page::query_selector for single element lookup
- Updated examples/basic.rs with full interaction demo
Part of #169
* feat(api): add Browser::cookies() method
* refactor(api): move to obscura crate with feature flag
- Renamed obscura-api → obscura (per maintainer feedback #169)
- API enabled by default via 'api' feature flag
- Usage: cargo add obscura (default=api) or cargo add obscura --features api
- Removed separate obscura-api crate
* chore: exclude docker workflow from fork
* fix(api): make the obscura crate build, run, and document install correctly
- examples/basic.rs and the lib.rs doctest imported `obscura_api`, but the crate
is named `obscura`, so both failed to compile. Use the real crate name.
- wait_for_selector / query_selector read the node id with `Value::as_u64`, but
`evaluate` returns JS numbers as f64, so it was always None and every
wait_for_selector timed out. Accept an integer or a non-negative finite float.
- restore .github/workflows/docker.yml, which the PR removed (a fork-specific
change that should not land upstream).
- add crates/obscura/README.md with honest install instructions: the crate is not
on crates.io, so depend on it via git (and it builds the embedded V8 from
source). The `cargo add obscura` form does not work yet.
Verified: workspace + example build, the lib doctest passes, the example runs end
to end (goto, wait_for_selector, text, attribute), and the integration suite is
28/28 with no regressions.
