* Get around monkey patched Nodes
* inlineImages: Setting of `image.crossOrigin` is not always necessary (#1468)
Setting of the `crossorigin` attribute is not necessary for same-origin images, and causes an immediate image reload (albeit from cache) necessitating the use of a load event listener which subsequently mutates the snapshot. This change allows us to avoid the mutation of the snapshot for the same-origin case.
* Modify inlineImages test to remove delay and show that we can inline images without mutation
* Add an explicit test for when the `image.crossOrigin = 'anonymous';` method is necessary. Uses a combination of about:blank and our test server to simulate a cross-origin context
* Other test changes: there were some spurious rrweb mutations being generated by the addition of the crossorigin attribute that are now elimnated from the rrweb/__snapshots__/integration.test.ts.snap after this PR - this is good
* Move `childNodes` to @rrweb/utils
* Use non-monkey patched versions of the `childNodes`, `parentNode` `parentElement` `textContent` accessors
* Add getRootNode and contains, and add comprehensive todo list
* chore: Update turbo.json tasks for better build process
* Update caniuse-lite
* chore: Update eslint-plugin-compat to version 5.0.0
* chore: Bump @rrweb/utils version to 2.0.0-alpha.15
* delete unused yarn.lock files
* Set correct @rrweb/utils version in package.json
* Migrate over some accessors to reverse-monkey-patched version
* Add missing functions
* Fix illegal invocation error
* Revert closer to what it was.
This feels incorrect to me (Justin Halsall), but some of the tests break without it so I'm restoring this to be closer to its original here:
cfd686d488/packages/rrweb-snapshot/src/snapshot.ts (L1011)
* Reverse monkey patch all methods LWC hijacks
* Make tests more stable
* Safely handle rrdom nodes in hasShadowRoot
* Remove duplicated test
* Use variable `serverURL` in test
* Use monorepo default browserlist
* Fix typing issue for new typescript
* Remove unused package
* Remove unused code
* Add prefix to reverse-monkey-patched methods to make them more explicit
* Add default exports to @rrweb/utils

rrweb-snapshot
Snapshot the DOM into a stateful and serializable data structure. Also, provide the ability to rebuild the DOM via snapshot.
API
This module export following methods:
snapshot
snapshot will traverse the DOM and return a stateful and serializable data structure which can represent the current DOM view.
There are several things will be done during snapshot:
- Inline some DOM states into HTML attributes, e.g, HTMLInputElement's value.
- Turn script tags into
noscripttags to avoid scripts being executed. - Try to inline stylesheets to make sure local stylesheets can be used.
- Make relative paths in href, src, CSS to be absolute paths.
- Give an id to each Node, and return the id node map when snapshot finished.
rebuild
rebuild will build the DOM according to the taken snapshot.
There are several things will be done during rebuild:
- Add data-rrid attribute if the Node is an Element.
- Create some extra DOM node like text node to place inline CSS and some states.
- Add data-extra-child-index attribute if Node has some extra child DOM.
serializeNodeWithId
serializeNodeWithId can serialize a node into snapshot format with id.
buildNodeWithSN
buildNodeWithSN will build DOM from serialized node and store serialized information in the mirror.getMeta(node).
