Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

NPM JavaScript Style Guide

Install

Npm

npm install --save cognito-oauth-library

Yarn

yarn add cognito-oauth-library

How it works

First you need to pass all required settings to the cognito-oauth-library.

config.jsx

import React from 'react';

import { Cognito } from 'cognito-oauth-library';

const cognito = new Cognito({
  clientId: '<Your-Client-Id>',
  domain: '<Your-Cognito-Domain>',
  region: '<Your-AWS-Region>',
  responseType: '<code|implicit>',
  redirectUri: '<Your-Redirect-Uri'
});

export default cognito;

After this you'll be able to access all components from the library

Components

The components only work inside of a Session Context.

How to use Session Component

This component will provide you every information you need from the authentication. It is a Provider from React Context API and it will allow you to share an Authentication context along all children components inside <Session/>

SessionComponent.jsx

import React from 'react';

import { Session } from 'cognito-oauth-library';

import cognito from './config';

<Session cognito={cognito}>
  <MyComponent />
</Session>

MyComponent.jsx

import React, { useContext } from 'react';
import { SessionContext } from 'cognito-oauth-library';

function MyComponent(){
  const session = useContext(SessionContext);

  return (
    <div>
      <a href={session.cognito_url}>Sign In</a>
    </div>
  );
}

How to use Session Context

You can use SessionContext to get all informations from the authentication shared context.

| Property | Description | |- |- | | cognito_url | Authentication url for Cognito Sign In UI | | user | All data from oauth2/userinfo endpoint | | | |

Context Usage

import React, { useContext } from 'react';
import { SessionContext } from 'cognito-oauth-library';

const session = useContext(SessionContext);

Api Service

This library also provides you, a Axios instance with some plus configurations like, it adds your token into all requests and when your API returns 401 error code, it automatically tries to refresh your token.

How to use Api Service

Api.js

import cognito from './config';

const Api = cognito.createApi({
  baseUrl: `<Your-Api-Url-Here>`,
  headers?: {
    '<Your-Header-Name>' : '<Your-Header-Value>'
  }
});

export default Api;

With that, you can have access into get, post, update and delete methods from Axios.
