Prevent spamming of api calls when Refresh is pressed or back + forward continuously

What I need to do is store the user's results of the first call and then either cache or localstorage / sessionstorage so when the user presses the buttons mentioned above, the page will load that data instead of doing multiple calls. I also need a timer to do another call after an hour to update for any weather changes. Any ideas on this?

MDOP•12mo ago

right now I just have backend code no js yet just something im working on with js in this file called storedData.js

// adding code to store the user's session
const pageReloadCheck = (
    (window.performance
        .getEntriesByType('navigation')
        .map((nav) => nav.type)
        .includes('reload')    
    )
);

alert(pageReloadCheck)

    )
);

alert(pageReloadCheck)

test code but in theory it should be able to check for reload and back + forward then I write a function to convert the table data into json to stringify it so I can make a key value pairing for the storage tbh I never worked with caching much espeically in web

you really should add some caching, even if it is an horrible globa variable to store what you fetch from the api take care of the server first, then think about the client

MDOP•12mo ago

ok so cache the api results

ἔρως•12mo ago

yes, in the server now, you have to think about how you will cache it

MDOP•12mo ago

not sure how go does that

ἔρως•12mo ago

one thing you can do is to check if whatever you're using to get the stuff from the api is using http 1.1 or higher

MDOP•12mo ago

really right now I have to see why my code stopped working completely

ἔρως•12mo ago

good luck debugging it

MDOP•12mo ago

ill be back when I get that resolved

ἔρως•12mo ago

alright, take your time

MDOP•12mo ago

Like usual it's the regex

ἔρως•12mo ago

MDOP•12mo ago

The issue is I type "Lexington" or "Columbus" and it crashes

ἔρως•12mo ago

because of the 2nd regex

MDOP•12mo ago

The if statement I need to evaluate that differently

ἔρως•12mo ago

i don't know what you're trying to do, but, im not sure if it is even a good approach

MDOP•12mo ago

It handles the case of entering a city like Lexington then the other is for those same city different state like Charleston, WV vs Charleston, SC

ἔρως•12mo ago

did you tested it in regex101 or something?

MDOP•12mo ago

Yeah Regex works The if failed

ἔρως•12mo ago

the if looks ... iffy

MDOP•12mo ago

Yeah I goofed it up I'll fix it first tomorrow then try the next step

ἔρως•12mo ago

good luck
