Fetcher

Decorators that makes fetch friendly.

Getting started

Use a fetch-like function with extra features, thanks to provided decorators.

import { useAll } from 'https://deno.land/x/fetcher/mod.ts'

type Data = { name: string; username: string }

const email = 'Lucio_Hettinger@annie.ca'

const baseURL = 'https://jsonplaceholder.typicode.com'
const fetcher = useAll<Data[]>({ baseURL })
try {
  console.log('Fetching /users from jsonplaceholder…')
  const data: Data[] = await fetcher.fetch(
    '/users',
    { query: { email }, timeout: 5000 },
  )
  const { name, username } = data[0]
  console.log('Success!')
  console.log('Result:', { name, username })
} catch (err) {
  console.error(err)
}

Features

• Base URL
• Basic auth
• Bearer
• Defaults
• Error handling
• JSON response & payload
• Query params
• Timeout

Usecases

useAll() returns a fetcher object decorated with all the decorators, enabling all the features in one.

If you don’t need all the features, feel free to customize your fetcher instance with the decorators you want.

Examples :

• POST a JSON payload with a base URL

  import {
    useBaseURL,
    useJsonResponse,
  } from 'https://deno.land/x/fetcher/mod.ts'
  
  const baseURL = 'https://dummyjson.com'
  const username = 'kminchelle'
  const password = '0lelplR'
  
  const fetcher = useJsonResponse(useBaseURL())
  
  type Data = {
    id: number
    username: string
    email: string
    firstName: string
    lastName: string
    gender: string
    image: string
    token: string
  }
  
  const data = await fetcher.fetch<Data>('/auth/login', {
    baseURL,
    method: 'POST',
    json: { username, password },
  })
  
  console.log('data:', data)
