[data.ui] Lazy load UI components in data plugin. by lukeelmers · Pull Request #78889 · elastic/kibana

lukeelmers · 2020-09-29T23:35:55Z

In an effort to reduce the initial bundle size of the data plugin, this updates items exported from data/public/ui to be lazy-loaded.

There's more we could investigate in the data plugin longer term, but this is the quickest/easiest target for bundle size reduction that doesn't involve breaking any service contracts or making lifecycle methods async.

Here are the before and after stats from webpack-bundle-analyzer:

Before: `data/public/ui` ~307k

Data Plugin

Closeup of data/public/ui

After: `data/public/ui` ~37k

These cleanups should no longer be needed as explained in #78742

src/plugins/data/public/ui/index.ts

data/public/index.ts imports from this file, so I have removed any items which are imported internally by other lazy-loaded components. This way the only items available in ui/index are types, or lazy-loaded components.

src/plugins/data/public/ui/query_string_input/query_string_input.test.tsx

waitFor already fails if the items you are querying for don't exist, so we no longer need the assertions that were here previously.

src/plugins/data/public/ui/search_bar/search_bar.test.tsx

TBH I have no clue how this test worked previously with the .filterBar class... I couldn't find it anywhere in the DOM. So I replaced it with .globalFilterBar which definitely exists 🙂

x-pack/plugins/security_solution/public/common/components/query_bar/index.test.tsx

React.Suspense doesn't play nice with Enzyme, but I wanted to avoid re-writing each test with @testing-library/react since I'm not familiar with this area of code. So I made this wrapper which ensures the SearchBar that's loaded with React.lazy is available before Enzyme mount is called.

You may want to consider a rewrite with @testing-library/react that doesn't rely on <SearchBar /> internals, as it should speed these tests up a bit. (Or perhaps a functional test if you really want to test the end-to-end experience).

After several attempts, I've been unable to reproduce these failures locally, however they are failing consistently so I'll keep investigating.

I haven't had any luck getting to the bottom of this failed maps functional test, so I've pinged @elastic/kibana-gis for input:

[00:07:24]                 └- ✖ fail: maps app  blended vector layer should request documents when zoomed to smaller regions showing less data
[00:07:24]                 │      Error: expected '34' to equal '33'

Since this test doesn't appear to have been failing on other branches lately, I'm trying to figure out what I changed that might have affected this test. The two components which are now lazy loaded that I could find usage of in the maps app are SearchBar and IndexPatternSelect.

One hypothesis I had was that perhaps the SearchBar was loading more slowly in CI, causing the map to temporarily render at a larger size and thus include a wider area in the query, resulting in the one additional hit that comes back (34 instead of 33).

I did a few things to try to reproduce the failure locally:

Tried throttling network speed.
Tried manually delaying rendering of the SearchBar and IndexPatternSelect.
Tried removing the SearchBar completely to see if it changed the results.
Looked at the PageObjects.maps methods to see if there were any obvious places that race conditions might occur.

In all cases I was still unable to reproduce the failure 🙁

The screenshot from the test artifacts doesn't show any obvious rendering problems either:

At this point I've adjusted the height of the SearchBar fallback component to see if it helps (so that the UI doesn't "jump" as that component loads).

But if this next run still fails, I might need some more expertise from @elastic/kibana-gis.

+      // Allow a range of hits to account for variances in browser window size.
+      expect(parseInt(hits)).to.be.within(30, 40);


Discussed with @nreese, and he agreed that in this case it would be fine to make this assertion a range of values to account for small variances in screen size.
