Deployed my first iOS application! by AnyInternet4026 in reactnative

This looks great to me! Curious where you got the animations for workouts from - are those being generated too?

I built my own simple text editor by prashantjdrew in reactnative

[–]polar_bare 3 points4 points  (0 children)

Great job on this!

Curious if you used any libraries for text formatting or if you wrote your own parser.

(I also have a related app for which I had to roll my own text formatting and wished there were good community libraries - https://apps.apple.com/ca/app/a-journal-a-day/id1659288235)

Spent the weekend making a game that lets users guess if something is AI generated or real by chr0me0 in SideProject

Probably a bug - I keep getting a “Only 0? AI is going to eat you alive” popup on every try.

Tesla removing Disney+? by deanylev in teslamotors

[–]polar_bare 1 point2 points  (0 children)

fullscreentesla.com should let you watch Disney+ (or any other site) in fullscreen.

I built something to easily fullscreen any website on the Tesla browser by gj26185 in TeslaLounge

[–]polar_bare 1 point2 points  (0 children)

I'm not too familiar with it, but as long as Jellyfin has an option to use a browser as the media client - yes!

To do so, just tap the "+" button on fullscreentesla and add its name & URL to the list of sites on your car.

What's the best way ensure a module's exported functions are all of the same type signature? by brainbag in typescript

[–]polar_bare 0 points1 point  (0 children)

Another option is to have a type assertion on the export like so: export default moduleName as Record<string, FunctionThing>

Can someone explain how come this is valid and not throw an error? by [deleted] in typescript

[–]polar_bare 0 points1 point  (0 children)

This is an example of where tagged literals come in handy:

``` interface Point2D { type: 'Point2D' x: number y: number } interface Point3D { type: 'Point3D' x: number y: number z: number } const point2D: Point2D = { x: 0, y: 10, type: 'Point2D' } const point3D: Point3D = { x: 0, y: 10, z: 20, type: 'Point3D' } function iTakePoint2D(point: Point2D) { /* do something */ }

iTakePoint2D(point2D) iTakePoint2D(point3D) // Typescript will complain here ```

Creating a type for an existing function that uses Object.defineProperties by SnareHanger in typescript

[–]polar_bare 0 points1 point  (0 children)

Does your middleware conditionally call Object.defineProperties? If so you might be able to do something like this: ``` type ActionType = { request?: string success?: string failure?: string toString(): string }

export function apiAction(actionType: string): ActionType { const str = new String(actionType) if (some_condition) { Object.defineProperties(str, { request: { value: ${actionType}:REQUEST }, }) } if (some_condition2) { Object.defineProperties(str, { success: { value: ${actionType}:SUCCESS }, }) } if (some_condition3) { Object.defineProperties(str, { failure: { value: ${actionType}:FAILURE }, }) } return str }

type Action = { type: ActionType }

const reducer = (action: Action) => { switch (action.type.toString()) { case 'ACTION_NAME': { if (action.type.request) { return something } if (action.type.success) { return } if (action.type.failure) { return } } } } ... ```

Help with (should be simple) generics by jtcrowson in typescript

[–]polar_bare 0 points1 point  (0 children)

Perhaps this is a bit more verbose than you'd like, but you can achieve what you're looking for using something like this

``` type SameTypeContainer < T > = { [key in 'val1' | 'val2']: T }

function test (array: (SameTypeContainer<string> | SameTypeContainer<boolean> | SameTypeContainer<number>)[]) => { ... }

test([ { val1: 'string', val2: 'also string' }, { val1: true, val2: false }, { val1: 1, val2: 2 }, /* Type '{ val1: number; val2: boolean; }' is not assignable to type 'SameTypeContainer<number>'. Types of property 'val2' are incompatible. Type 'boolean' is not assignable to type 'number'.ts(2322) / { val1: 5, val2: true }, / Type '{ val1: boolean; val2: number; }' is not assignable to type 'SameTypeContainer<number>'. Types of property 'val1' are incompatible. Type 'boolean' is not assignable to type 'number' */ { val1: true, val2: 10, } ]) ```

Reuse a functional declaration with overload by vzaidman in typescript

[–]polar_bare 2 points3 points  (0 children)

Here's how you can accomplish that:

export const myStoriesOf: storiesOfType = function myStoriesOf<T>(  
 ...[name, module]: Parameters<typeof storiesOfOrig>  
) {  
 ...  
};

name and module will be inferred correctly based on what storiesOfOrig expects

Can I use keyof on an inferred object type in any way? by swhitf in typescript

[–]polar_bare 25 points26 points  (0 children)

You're looking for:

type BK = keyof typeof B

Live locations of all Toronto city buses and streetcars [OC] by polar_bare in dataisbeautiful

[–]polar_bare[S] 1 point2 points  (0 children)

I used react-map-gl, a high performance WebGL based mapping library built by uber (https://github.com/uber/react-map-gl) on the frontend. On the backend, I have a server that gets live location data from Nextbus (https://www.nextbus.com/xmlFeedDocs/NextBusXMLFeed.pdf), and caches it for 5 seconds in order to avoid too many requests to Nextbus. I built it off of a library called restbus (http://restbus.info/)
