Fetchum

A better fetch api

The main bulk of the local storage wrapper has been moved out into betterstorage. The token related methods still exist but are now promise based.

Install

npm i -S fetchum

yarn add fetchum

Setup

<script>
  window.FETCHUM_BASE = 'localhost:3000/api';
  window.FETCHUM_PREFIX = '@my-app';
</script>

For use Node side set env vars ie:

process.env.FETCHUM_BASE = 'localhost:3000/api';
process.env.FETCHUM_PREFIX = '@my-app';

For universal set both.

import fetchum from 'fetchum';

fetchum.setConfig('/api/', '@app-prefix');

Api - generateRequest

generateRequest returns a function to call that will make a request based on set options.

Options

• method : http verb
• route : url string
• headers : object for default request headers (default: {})
• form : boolean if submit as form data (default: false)
• token : boolean if set Auth header from local storage token (default: false)
• external : boolean if should not prepend route with api base (default: false)

Function Params

• params : json object matching keys for parameterized routes ie: /user/:id
• body : json request body/url params
• headers : json request headers
• customToken : !Only if external option is false
• tokenType : !Only if external option is false. Default Bearer.

Examples

import fetchum from 'fetchum';

const getRandomUser = fetchum.generateRequest({
  method: 'GET',
  external: true,
  route: 'http://uifaces.com/api/v1/random',
});

Create and update a user with profile image on a authenticated api

import fetchum from 'fetchum';

const postUser = fetchum.generateRequest({
  method: 'POST',
  form: true,
  token: true,
  route: '/v1/user',
});

const putUser = fetchum.generateRequest({
  method: 'PUT',
  form: true,
  token: true,
  route: '/v1/user/:id',
});

const createUser = (data) => {
  postUser({}, data)
    .then((res) => { console.log('created', res.data); })
    .catch((res) => { console.warn(res); });
};

const updateUser = (id, data) => {
  putUser({id}, data)
    .then((res) => { console.log('updated', res.data); })
    .catch((res) => { console.warn(res); });
};

Api - generateCRUDRequests

Like generateRequest generateCRUDRequests will generate request structure but it does more returning a object with all the basic crud actions.

Function Params

• baseUrl : url string to base crud actions off ie: /user
• idVar : the var name of the id url param id the :id in /user/:id. The : should not be passed.
• Defualt - 'id'
• useToken : if the routes should have the token option set.
• Defualt - false

Examples

import fetchum from 'fetchum';

const userApi = fetchum.generateCRUDRequests('/users', 'id', true);

userApi.fetchOne({ id: 0 })
  .then((res) => {
    this.user = res.data.user;
  });

Returned Requests

• fetchAll - GET to base url
• create - POST to base url
• fetchOne - GET to base url and added id Var ie: /users/:id
• update - PUT to base url and added id Var ie: /users/:id
• delete - DELETE to base url and added id Var ie: /users/:id

Api - LocalStorage

Fetchum has a build in LocalStorage wrapper for convenience and for the specific use of getting the auth token.

To use the token option in the generateRequest call you will need to use this LocalStorage wrapper;

Methods

• set - sets var in storage ie LocalStorage.set('varName', varValue)
• get - gets a var value from storage ie: const varValue = LocalStorage.set('varName')
• remove - removes a var from storage
• isSet - returns boolean for if a var is in storage
• setToken - sets a token in storage used by requests
• getToken - gets a token from storage
• removeToken - removes a token from storage

Examples

import {LocalStorage} from 'fetchum';

const setToken = (token) => {
  LocalStorage.set('token', token);
};

Login and out example

import fetchum from 'fetchum';

const apiLogin = fetchum.generateRequest({
  method: 'POST',
  route: '/v1/login',
});

const login = (data) => {
  apiLogin(data)
    .then((res) => {
      fetchum.LocalStorage.setToken(res.data.token);
      fetchum.LocalStorage.set('user', res.data.user);
    })
    .catch((res) => { console.warn(res); });
};

const getCurrentUser = () => {
  return fetchum.LocalStorage.get('user');
};

const logout = () => {
  fetchum.LocalStorage.remove('user');
  fetchum.LocalStorage.removeToken();
};

export default {
  login: fetchum.generateRequest({
    method: 'POST',
    route: '/v1/login',
  }),

    getAll: fetchum.generateRequest({
      method: 'GET',
      token: true,
      route: '/v1/users',
    }),
    show: fetchum.generateRequest({
      method: 'GET',
      token: true,
      route: '/v1/users/:id',
    }),
    update: fetchum.generateRequest({
      method: 'PUT',
      token: true,

  }
};

import { apiRequests } from 'fetchum';

const getUsersDirect = () => {
  apiRequests.get('/v1/users')
    .then((res) => { console.log('my users', res.data); })
    .catch((res, err) => { console.warn(res); });
};
