fetchyeah v5.1.0

fetchyeah

Tiny JSON fetch wrapper library. ~1.7kb gzipped.

fetchyeah is a small fetch wrapper library that always parses JSON and returns JS. Smaller than Axios, Request, R2, and the whatwg-fetch polyfill itself.

Installation

npm i fetchyeah

Usage

import { get } from 'fetchyeah'

get('/foo')

Methods

• del
• get
• patch
• post
• put

This only provides functions for these common HTTP methods, but you can easily add your own. Check out the source for notes on how to use sendJson directly.

The return value is always a simple response of type

type SimpleResponse<T> = {
  ok: boolean
  status: number
  headers: Headers
  body: T
}

Examples

Node:

require('isomorphic-fetch') // brings in fetch for Node

import * as f from 'fetchyeah'

// some koa route
router.get('/foo/:id', async (ctx) => {
  try {
    const thing = await f.get(`/some-service/${id}`)
    ctx.type = 'application/json'
    ctx.body = thing
  } catch (e) {
    someLogger.error(e)
    ctx.status = 500
    ctx.body = e
  }
})

Browser:

import * as React from 'react'
import { post } from 'fetchyeah'

class Foo extends React.Component {
  state = { things: null }

  submitThings = () => {
    post('/stuff', { body: this.state.things })
    .then((res) => {
      if (res) {
        alert(res)
      }
    })
    .catch((err) => {
      someErrorHandler(err)
    })
  }

  setThings = (e) => {
    this.setState({ things: e.target.value })
  }

  render () {
    return (
      <React.Fragment>
        <input
          type="text"
          onChange={this.setThings}
          value={this.state.things}
        />
        <button onClick={submitThings}>
          Send the things!
        </button>
      </React.Fragment>
    )
  }
}

Adding headers:

import { post } from 'fetchyeah'

post('/foo', {
  body: someObject,
  headers: {
    'x-foo-bar': 'baz',
  }
})

Environment

This library assumes fetch is available. You may need to polyfill it!
