## Issue
- Each tile was checking against 4 blocklists (blacklisted, filtered, muted, commentron) on every render. Loading the front-page with Cheese alone caused 1400 calls.
- This is also part of the reason why pressing Back into the tile list takes forever.
## Fix
Since we still need to perform the checks at the app side for now, tried to memoize the operation through a selector.
Now, with the exception of connecting to lbry.com after re-opening the browser (i.e. establishing first connection), refreshing odysee.com is almost instantaneous.
## Issue
85 Add additional GA events
## Approach
Instead of placing analytic calls all over the GUI code (no separation of concerns), try to do it through a redux middleware instead.
## Changes
- Updated GA event and parameter naming after understanding how reporting works.
- Removed unused analytics.
## Issue
Our `<CodeViewer>` and `react-simplemde-editor` uses `codemirror`, and they were each bundling a different version.
## Change
Re-generate yarn.lock for `codemirror`. Since we are upgrading anyway, upgraded to the latest and greatest.
## Test
- [x] Markdown editor -- looks ok. It inherited several fixes for code-blocks.
- [x] Code viewer -- looks ok.
Only picking components that are involved in a livestream for now. Ideally, all usages of `makeSelectClaimForUri` should be replaced -- will do it incrementally.
followedTags:
- Moved the filtering to the reducer side, so that we don't do it every time. We can't rely on `createSelector` because the store will be invalidated on each `USER_STATE_POPULATE`, unfortunately.
tags:
- Memoize via re-reselect for the "ForUri" selector.
## Issue
`makeSelectDataForUri` always returns a new reference, so `ClaimPreview` was constantly being rendered. It's pretty expensive since `ClaimPreview`'s rendering checks against a huge blocklist, which is another issue on it's own.
## Changes
- This commit tests the usage of `re-reselect` as the solution to the multi-instance memoization problem (https://github.com/toomuchdesign/re-reselect/blob/master/examples/1-join-selectors.md)
## Issue
When comments are refreshed, each `Comment` gets rendered 4-5 times due to reference invalidation for `othersReacts` (the data didn't actually change).
## Change
For selectors without transformation, there is no need to memoize using `createSelector` -- just access it directly. Also, don't do things like `return a[id] || {}` in a reducer, because the reference to the empty object will be different on each call.
Always return directly from the state so that the same reference is returned.
This simple change avoided the wasted resources needed for `createSelector`, and reduced to render to just 2 (initial render, and when reactions are fetched).
## Issue
Components render unnecessarily due to reference invalidation from `selectMutedChannels` selector.
## Notes
`selectMutedChannels` run and return a new reference each time the app gains focus. `createSelector` will not help in this case, because we are indeed invalidating the data in the store in `USER_STATE_POPULATE`.
## Changes
- Don't update the state if the array is identical in content.
- Fixed `selectMutedChannels` to return the reference from the store, so `createSelector` is not needed.
- Also, the filtering is not needed because we've already done it in the reducer.
## Comments
I've done some profiling on large blocklists. The time needed for the array comparison is still an order magnitude lower than the time needed to render all the Components that got incorrectly marked by this.
The ideal solution is for the sync code to return a hash or timestamp of the array, so that we can compare that instead of the array.
- Add `/extras` to the precommit hooks (lint, prettier).
- Remove `preinstall` since these modules don't exist anymore.
- Fix missing brace if one single-line if-statement.
- It is recommended to use "lowercase + underscore format" for events to keep things neat, since the dashboard will be mixed with Automated and Recommended events.
- GA4 event structure is no longer the same as UA's, and the recommendation is to retructure rather than trying to mimic the old pattern.
- Always check the Recommended events to see if there is an equivalent, and use the exact name. GA4 might add automated features for these events in the future, and we'll benefit from it without code changes and invalidating existing data.
- pageView: use default snippet behavior instead of manually sending
Start converting to GA4...
- Outbound click are automatically handled.

## Issue
Now that we batch-resolve the comment authors before displaying the comments, the linked-comment scrolling logic didn't work well with nested replies.
## Change
Previously, I didn't want to put the logic at the lowest level (`Comment`) because it was hard for the child to know whether to scroll or not. For example, we don't want to scroll when user changes the comment filters or presses the Refresh Comments button.
Relented and moved the logic to `Comment`, and pass a flag via `window` (I know this is frowned upon by some) to indicate whether a scrolling is needed.
This is probably more efficient overall as we don't need to scan the DOM, and with minimal delay as we scroll immediately after the linked-comment is mounted.
## Known issues
In markdown posts with lots of images, a layout shift due to delayed inline-image fetching can cause the scrolling to be inaccurate. This should be fixed by reserving space for markdown post images.
