pulse-agent bbdb68a6de feat(lib-core): biblioteca atomica @pulse-libs/core v1.0.0-beta.1
Esta commit conteudo a estrutura atomica completa:

- types:     Result<T,E>, AsyncState<T>, Paginated<T>, SortConfig<T>
- utils:     date, str, num, cn, debounce, throttle, storage, arr, obj
- validators: Zod schemas — email, password, uuid, url, phone, CPF/CNPJ, sanitizedStr, safeParse
- hooks:     useToggle, useAsync, useDebounce, useLocalStorage, useMedia, useInterval, useOnClickOutside, useClipboard, useFetch
- components: Button, Input, Alert, Card, Spinner (atomic design pattern)
- build:     tsup v8 ESM+CJS + DTS + sourcemaps — 0 erros
- tests:     57 testes 100% usuarios
- docker:    multi-stage Dockerfile (node 20-alpine)
- config:    vitest, tsup, tsconfig strict, .npmignore

thenify

NPM version Build status Test coverage Dependency Status License Downloads

Promisify a callback-based function using any-promise.

  • Preserves function names
  • Uses a native promise implementation if available and tries to fall back to a promise implementation such as bluebird
  • Converts multiple arguments from the callback into an Array, also support change the behavior by options.multiArgs
  • Resulting function never deoptimizes
  • Supports both callback and promise style

An added benefit is that thrown errors in that async function will be caught by the promise!

API

fn = thenify(fn, options)

Promisifies a function.

Options

options are optional.

  • options.withCallback - support both callback and promise style, default to false.

  • options.multiArgs - change the behavior when callback have multiple arguments. default to true.

    • true - converts multiple arguments to an array
    • false- always use the first argument
    • Array - converts multiple arguments to an object with keys provided in options.multiArgs
  • Turn async functions into promises

var thenify = require('thenify');

var somethingAsync = thenify(function somethingAsync(a, b, c, callback) {
  callback(null, a, b, c);
});
  • Backward compatible with callback
var thenify = require('thenify');

var somethingAsync = thenify(function somethingAsync(a, b, c, callback) {
  callback(null, a, b, c);
}, { withCallback: true });

// somethingAsync(a, b, c).then(onFulfilled).catch(onRejected);
// somethingAsync(a, b, c, function () {});

or use thenify.withCallback()

var thenify = require('thenify').withCallback;

var somethingAsync = thenify(function somethingAsync(a, b, c, callback) {
  callback(null, a, b, c);
});

// somethingAsync(a, b, c).then(onFulfilled).catch(onRejected);
// somethingAsync(a, b, c, function () {});
  • Always return the first argument in callback
var thenify = require('thenify');

var promise = thenify(function (callback) {
  callback(null, 1, 2, 3);
}, { multiArgs: false });

// promise().then(function onFulfilled(value) {
//   assert.equal(value, 1);
// });
  • Converts callback arguments to an object
var thenify = require('thenify');

var promise = thenify(function (callback) {
  callback(null, 1, 2, 3);
}, { multiArgs: [ 'one', 'tow', 'three' ] });

// promise().then(function onFulfilled(value) {
//   assert.deepEqual(value, {
//     one: 1,
//     tow: 2,
//     three: 3
//   });
// });
