@nefty/use

use

⚡️ Under heavy development. Pin your NPM version!!!! before consumption. ⚡️

Useful methodes we use daily in our projects. Most methodes you probably find in your favorite framework, but we needed something you can use everywhere.

• vueUse for Vue projects.
• reactuses for React projects.

Most functions lack proper checking as we require you to still think about what you are doing.

It's all typed so you should be good to go.

usePosthog

Posthog analytics

import { usePosthog } from '@nefty/use';

// init with extra options
const analytics = usePosthog({
    version: 'v2',
});

// track an event
analytics.track('event-name', {
    // data
});

// identify a user
analytics.identify('user-id');

useAssetData

Get data from a template (WAX api only)

import { useAssetData } from '@nefty/use';

const template = {...};

const asset = useAssetData(template);

if(asset) {
    const { name, img } = asset;
}

useImageUrl

Create resized image url from a CID or url (works only for allowed domains)

import { useImageUrl } from '@nefty/use';

// resize to 100x100 and make it static
useImageUrl('https://example.com/image.png', 100, true);

useFetch

Small wrapper around native fetch to stringify body and parse parms as an object (not doing polyfilling)

No need for a try catch, this is done iternaly.

// GET request
import { useFetch } from '@nefty/use';

const { data, error } = await useFetch<DataType>('/api/data', {
    baseUrl: 'https://example.com',
    headers: {
        'Content-Type': 'application/json',
    },
    // params values needs to be of type String
    params: {
        account: 'example',
        filter: 'all',
        limit: '100',
        sort: 'desc',
    },
});

if (error) // do something with the error
else {
    // do something with the data
}

// POST request
import { useFetch } from '@nefty/use';

const { data, error } = await useFetch<DataType>('/api/data', {
    baseUrl: 'https://example.com',
    methode: 'POST',
    headers: {
        'Content-Type': 'application/json',
    },
    body: {
        account: 'example',
        filter: 'all',
        limit: 100,
        sort: 'desc',
    },
});

if (error) // do something with the error
else {
    // do something with the data
}

// All options
import { useFetch } from '@nefty/use';

const { data, error, header, time } = await useFetch<DataType>('/api/data', {
    baseUrl: 'https://example.com',
});

console.log(header['content-type']); // returns the content-type header
console.log(time); // returns the time it took to fetch the data

useSWR

SWR is a clientside caching (Stall While Revalidate) just to save some bytes and a way to clear the cache and have a new dataset.

import { useSWR } from '@nefty/use';

const forceRefresh = false;

// default timeout is 10 minutes
await useSWR(`unique-name`, () => getData(), 600_000, forceRefresh);

useRetry

Retry useFetch a certain amount of times with a delay between each try.

import { useRetry } from '@nefty/use';

const { data, error, header, time } = await useRetry({
    retries: 3, // default 3
    delay: 1000, // default 1000
    retryOn: ({ error }) => error !== null,
    call: () =>
        useFetch<DataType>('/api/data', {
            baseUrl: 'https://example.com',
        }),
});

useAvatar

Fast and beautiful dynamic avatar based on account name

import { useAvatar } from '@nefty/use';

useAvatar('example'); // returns a svg as a string

useMarkdown

useMarkdown('example'); // returns a string: <p>example</p>

// with options (source, render as html, class)
useMarkdown('example', true, 'class-name'); // returns a DOM element: <div class="class-name"><p>example</p></div>

useSearch

Fast search engine with support for typos

import { useSearch } from '@nefty/use';

const search = useSearch({
    // simple list of strings
    items: ['example', 'example 2'],
    // OPTIONAL: sorted list of strings per first character (good for many items)
    //  will fallback to items if no results are found to prevent empty results
    sorted_items: {
        a: ['account', 'account 2'],
        e: ['example', 'example 2'],
    },
    // OPTIONAL
    options: {
        distance: 3, // default 3: max distance between characters in a typo
        results_count: 8, // default 8: how many matches to return
        results_count_alt: 32, // default 32: how many alternative results with typos to look up (caped to results_count)
    },
});

const result = search('exa'); // returns [example', 'example 2'],

useColor

String to hsla color

import { useColor } from '@nefty/use';

useColor('example'); // returns a hsla color string

useCountDown

Countdown displayer, in DHMS format

import { useCountDown } from '@nefty/use';

useTokenDisplay(100, 2); // returns 100

useTokenDisplay(100, 2, true); // returns 100.00

WalletUAL

Wallet management for UAL. not going to go in to much details here, but you can find more info on the UAL

import { WalletUAL, WalletUser } from '@nefty/use/wallet';

const callback = (users: WalletUser[]): void => {};

const wallet_anchor = new Anchor([network], { appName });
const wallet_wax = new Wax([network]);
const wallet_wombat = new Wombat([network], { appName });

const provider = new WalletUAL(callback, [network], appName, [wallet_anchor, wallet_wax, wallet_wombat]);

provider.init();
