rABCd42543241000: [Cashtab] Convert wallet context to ts
Summary

Troubleshooting load speed issues in Cashtab. Need to get typescript at the highest level so I can find any mismatches. Start here.

Cashtab screens load important wallet information from Context. But, because type definitions have not been applied there, we aren't really getting a lot of typescript benefits on our screens.

Implement typescript on context file and at entry point of app. This required also implementing it in our GoogleAnalytics, which is loaded from this screen. We also see many "lint-like" changes in tsx files of app screens -- this is because, before context was updated, they were not actually getting the types of wallet context.

With typescript, implement improved condition check on context loading.

This is part of a broader effort to debottleneck Cashtab load times.

Test Plan

npm test, arc lint no ts errors

Instead of returning null, should this be returning a standard error component instead of a blank page?

cashtab/src/components/Etokens/Token/index.tsx
182 ↗(On Diff #51407)

at this point is the tokenid, if exists, guaranteed to always being a valid 64 char hex?

1634 ↗(On Diff #51407)

This is still a technical possibility isn't it? Don't think this affects performance.

2680 ↗(On Diff #51407)

is this a linting thing? seems redundant if you're checking boolean

apparently this is the right way to do it.

It's a bit moot since in practice I do not think context ever fails to load. I do not know how this would happen since it's not something I'm able to recreate.

cashtab/src/components/Etokens/Token/index.tsx
182 ↗(On Diff #51407)

no -- it just needs to be any string

we validate it right below on line 187, and have a test setup to show we render expected component if this is not valid

the route only renders if we have some kind of string for tokenId

1634 ↗(On Diff #51407)

this is no longer possible. we do not render the component at all if context does not load (return null above). if context loads, then pk is defined, and changescript is defined.

2680 ↗(On Diff #51407)

yes, it's a ts issue

isuse is that nftListPriceError is either false or string -- but disabled will only take booleans.

it "works" because a string is truthy. But nftListPriceError !== false is the "right" way to pass the boolean, which ts requires.

bytesofman marked 4 inline comments as done.
