My PWA had been working fine for several years until recently. Now, it seems there is a new problem with the keyboard because I cannot type anything at all.
My bug, in my opinion, is related to another well-known issue: "Web apps are resized against our will when we open the keyboard." (I'm wondering how Twitter does since it doesn't resize when I do click on the input).
These are some pieces of my code. I wrote them trying to prevent the app to be resized:

QUESTION
I'm struggling to find the best way to display a countdown timer per item when mapping an array of values in to HTML.
I'm working on a project where I access values from an API and display them in a card format on my website. All the information displays as intended, but I cannot figure out how to display a unique countdown timer for each card.
Currently, I'm attempting to run a function at each mapping iteration that would generate the countdown and display on the id of 'countdownId'. This doesn't work as I get the error of 'Uncaught TypeError: Cannot set property 'innerHTML' of null'. I know this is because the id isn't generated at the time of the function running, but I cannot figure out an alternative way to display an actual countdown. I've tried to research and it hasn't gone anywhere.
Appreciate any help in advance.
Index.html - Limited this to relevant ID associated with displaying all cards.
...ANSWER
Answered 2021-Mar-31 at 02:34Let's break this into two parts.
First is just getting things printing out in the DOM. You correctly identified that the Cannot set property 'innerHTML' of null' error was because the element wasn't inserted into the DOM yet. On top of that, I see two more problems:
- You have a variable named
rocketCardinside a function calledrocketCard. You're asking for trouble there because any time you try to access that variable that holds your markup you're liable to end up calling the function on accident instead. So to keep debugging easier, I've renamed the function to something that's more inline with what it actually does:initDom. - You're using the same ID –
countdownId– for every countdown. So even if you do get the markup inserted into the DOM correctly, things aren't going to work. We need to generate a unique ID for each countdown.
Below I've changed the map to a forEach, which first inserts the element into the DOM (using innerHTML += instead of dumping the whole thing in at once at the end), then initializes the countdown.
QUESTION
I am trying to build a simple stopwatch app in react-native. I'm using AsyncStorage to store the time recorded data into local storage, along with that I would like to display a table that shows all the recorded times. The core idea is that when a person presses and holds a LottieView animation, it will start a timer, when they press out, the timer stops, records in AsyncStorage and then updates the table.
After 10 elements, my FlatList (inside TimeTable.jsx) becomes extremely slow and I am not sure why. The component that is causing this error is I believe TimeTable.jsx but I am not quite sure why.

QUESTION
TLDR: How do i send a short payload from a mqtt request to aws iot to aws lambda that has a open connection via apigateway to an electron app running locally in linux.
I have a esp8266 with the following code as the init.js This code succesfully sends it's message to aws iot, with a rule set to trigger a lambda called sendmessage. Now this sendmessage lambda is connected via websockets to a Electon app locally on my linux machine. I am able to send messages from the Electron app via websockets to api gateway wss url. I followed this example here which sets up all the websockets with api gateway and aws lambdas (one being the sendmessage lambda).
ANSWER
Answered 2020-Nov-17 at 04:59It seems like you're setting 1 lambda to handle 2 trigger sources, one is IoT service, the other is API Gateway Websocket. Since you use 1 lambda, you have to handle cases when the request is came from sources:
- While
event.requestContextis available when the request is triggered from API Gateway, it is not available when the request is triggered from IoT service (check the IoT event object here https://docs.aws.amazon.com/lambda/latest/dg/services-iotevents.html). So the error you faced (which isCannot read property 'domainName' of undefined") is about that. You should turn off the lambda trigger from IoT service or handle the request when it comes from IoT Service. - I'm not sure about the forbidden error but it is more like you sent unstructured message to API gateway WS, it should be
connection.send(JSON.stringify({ action: "sendmessage", data: "hello world" }));instead ofconnection.send("hello world");
Edited based on post update:
I know ws is there because if I console it it returns a big object with a bunch of functions
Lambda function is not really a server, it is an instance Node environment (that's why it is called FUNCTION), Lambda function doesn't work as the way you think normal Nodejs app does, its container (node environment) usually is halted (or freeze) whenever its job is done so you cannot keep its container alive like a normal server. That's the reason while you can console log the Websocket object, you cannot keep it alive, the NodeJS container was already halted whenever you return/response.
Since you cannot use the Websocket object to open WS connection in Lambda, Amazon offers a way to do that via API Gateway. The way we work with API Gateway Websocket is different than the normal server does too, it would be something like:
- User -> request to API Gateway to connect to websocket -> call Lambda 1 (onconnect function)
- User -> request to API Gateway to send message over Websocket -> call Lambda 2 (sendmessage function)
- User -> request to API Gateway to close connection -> call Lambda 3 (ondisconnect function)
3 settings above is configured in API Gateway (https://docs.aws.amazon.com/apigateway/latest/developerguide/apigateway-websocket-api-integrations.html), logic of 3 functions onconnect, sendmessage, ondisconnect can be handled in 1 lambda or 3 lambda functions depending on the way we design, I check your 3 lambda functions and it looks okay.
I see that you want to use IoT but I'm not sure why. You should test your Websocket API first without anything related to IoT. It would be better if you can tell what you want to achieve here since IoT works more like a publish/subscribe/messaging channel and I don't think it's necessary to use it here.
QUESTION
I have been working on a timer that is displaying 3 preset times based on the user's choice. I decided to include a countdown graphic in the shape of a clock which only has one hand and rotates 360 degrees for the full length of time assigned to it.
The problem I have is marrying up the original timer and the new display. I have the "clock" element drawn with canvas and I have a working timer, but I need to know how to take that time and utilise it to get the hand to move around. As it currently stands the hands will draw when I have it functioning, but don't display mostly because I haven't set an interval for the clock but I do have one for the original timer.

Answered 2020-Oct-31 at 02:03The first issue you have is that you only call clock() once - at the end of your script to initialise it.

I have a button which I am trying to use as a start and stop for an event which starts or stops a countdown timer. However it currently only starts and changes to the stop but will not change back to start or stop the timer from counting down.
Is there a better way of doing this? I've also included the reset button as I've tried to reset things when it it's pushed but it currently just changes back to the start, but the start won't fire again after I have done this.

Explanation: I am creating a fitness app, my fitness app has a component called WorkoutTimer that connects to the workout screen, and that screen is accessed via the HomeScreen. Inside the WorkoutTimer, I have an exerciseCount useState() that counts every time the timer does a complete loop (onto the next exercise). I have a different screen called StatsScreen which is accessed via the HomeScreen tab that I plan to display (and save) the number of exercises completed.
What I've done: I have quite literally spent all day researching around this, but it seems a bit harder with unrelated screens. I saw I might have to use useContext() but it seemed super difficult. I am fairly new to react native so I am trying my best haha! I have attached the code for each screen I think is needed, and attached a screenshot of my homeScreen tab so you can get a feel of how my application works.

This is code I collected from a video to learn react with hooks. It's supposed to create and name 3 timers from data hard coded and allow the user to create/name new timers. My code isn't exactly the same as the video because I couldn't get his to work at all.
The Problem is: I can get it to display the name for the user input timer or the hard coded timers, but not both. Right now it will display the name for the user input timer, but not the hard coded ones.

Answered 2020-Sep-16 at 05:08Your initial state is array of strings. And in your onSubmit you're updating your state with an object.
This is supposed to be a string.
