Strapi wouldn’t be anything without its community, which is very much represented by its Community Stars. The Write for the Community program resulted in 148 new articles being published, for a total of 1.3M views. 2022 was also the year of the launch of the Strapi Community Organization, a group of community members dedicated to empowering initiatives and highlighting them. Boaz, Mattie, Sacha, and Simen have been invaluable contributors to the Strapi Community, going above and beyond by developing open-source plugins and tools. Strapi config-sync plugin, mattie-strapi-bundle (for search), Strapi REST cache plugin, Dockerize tool, and more!

None of this would have been possible without the amazing Strapi community. To reinforce our commitment to open-source, we’d like to highlight the amazing work made by the Strapi Community Organization, thank the organizers of Strapi events, and acknowledge the amazing content made by the creators of the Write for the Community program.

💡 Tips: Instead of creating all your components from scratch, you can pick up examples directly from the strapi.io website and the official FoodAdvisor Demo.

With practice comes perfection. The only way to be a great technical writer is to write more. The more you write, the more you learn and get better. Once you are comfortable writing for the Write For the Community program at Strapi, you may also venture into contributing to making our documentation better.

While programming, programmers encounter various challenges, which make them solicit help with solving these problems. Forums provide a tech community of enthusiasts who can assist with these problems. We will be building a forum site with NextJs on the Front-end and Strapi for content management

Strapi

I'm taking this opportunity to thank them because this use case is very requested and their articles answer to a lot of questions. I want to emphasize that this type of contribution is very important for the Strapi community and if you wish to be part of it, I invite you to join our Write for the Community Program.

Open-Source: Anyone can contribute to the source code and thus help, improve, fix issues, propose ideas, etc... Thanks to the community efforts, Strapi will always stay updated and product requests have more chance to be met. The project evolves next to the community and it is priceless. Beyond the code contributions, our community create a lot of educational resources like articles thanks to our Write for the Community program, videos on youtube, webinars, or plugins & providers that you'll probably use at some point: Awesome Strapi repository

The source code used in this tutorial can be found in the GitHub repo: Forum Application.

This component handles the layout of our display forum page. We also have a button here that directs the user to the page to upload new questions.

Meanwhile, in upload.js we have the following:

    import React from "react";
    import Uploadforum from "./Components/Uploadforum";
    function upload() {
      return (
        

          
        
      );
    }
    export default upload;

Enter fullscreen mode Exit fullscreen mode

Here, we simply added an import for the Uploadforum component into our page. In Uploadforum.js file we have a simple form to create new questions:

    import React from "react";
    import style from "../../styles/Home.module.css";
    import Link from "next/Link";
    function Uploadforum() {
      return (

              Forum

            </form>
          </div>
        </div>
      );
    }
    export default Uploadforum;

<p>In our <code>Uploadforum.js</code> file, we will add functionality to upload the contents of the form to Strapi. First, we will create two state variables to store the text from our <code>inputs</code>.<br>
</p>

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>    import { React, useState } from "react";

<p>Then we set these variables to the value of our form <code>input</code>.<br>
</p>

<div class="highlight js-code-highlight">

<p>Also we will a function to send these variables when we click our <code>button</code>.<br>
</p>

<p>We can create the <code>sendData</code> function above our <code>return</code>.<br>

<p>For our create functionality we will import the <code>createQuestion</code> function we defined in our <code>api</code> folder.<br>

<p>Then we pass in our data to this function.<br>

<p>We can now upload new questions to our Strapi <code>collection</code>. We will add the <code>Username</code> when we cover user authentication.</p>

<p>Next up, we will add functionality to answer questions in our <code>Displayforum</code> component.</p>

<h2>
  <a name="adding-functionality-to-answer-questions" href="#adding-functionality-to-answer-questions">
  </a>
  Adding Functionality to Answer Questions
</h2>

<p>Since we set a text field for our answers in our <code>collection</code>, it can only take in one value. To have multiple answers for a question, we will delete the Answers field and create another field for our Answers of type <code>json</code>.</p>

<p>With that done, here is an example of what a response from our API would look like:</p>

<p><a href="https://res.cloudinary.com/practicaldev/image/fetch/s--6ji2Py_9--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_880/https://paper-attachments.dropbox.com/s_C85777D6DFCF98E4EF331F9FA47DA97E3213CAFEB9DAD61A99F14E2CE8154E5F_1635601446784_new%2Bresponse.jpg" class="article-body-image-wrapper"><img src="https://res.cloudinary.com/practicaldev/image/fetch/s--6ji2Py_9--/c_limit%2Cf_auto%2Cfl_progressive%2Cq_auto%2Cw_880/https://paper-attachments.dropbox.com/s_C85777D6DFCF98E4EF331F9FA47DA97E3213CAFEB9DAD61A99F14E2CE8154E5F_1635601446784_new%2Bresponse.jpg" alt="" loading="lazy" width="586" height="423"></a></p>

<p>To display our answers, we will map through <code>Answers</code>:<br>
</p>

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>     {response.Answers.map((answers, i) => (
                      <div className={style.eachanswer} key={i}>
                        <p className={style.username}>{response.Answername}</p>
                        <p className={style.answertext}>{answers}</p>
                      </div>
                    ))}
</code></pre>
<div class="highlight__panel js-actions-panel">
<div class="highlight__panel-action js-fullscreen-code-action">
    <svg xmlns="http://www.w3.org/2000/svg" width="20px" height="20px" viewbox="0 0 24 24" class="highlight-action crayons-icon highlight-action--fullscreen-on"><title>Enter fullscreen mode</title>

</svg>

</div>
</div>
</div>



<p>Now in our browser, if we add more <code>answers</code> to our JSON collection, we can see them displayed on our page.</p>

<p>We will repeat the same method as we did with our Upload <code>Question</code> functionality for the add answer functionality, but with a minor difference. In your <code>Displayforum</code> component, add the following code:<br>

<p>We will store the input from the <code>textarea</code> in <code>answer</code>. We will use the <code>id</code> variable to reference the collection we want to add the answer to.</p>

<p>Then in our form <code>textarea</code>:<br>
</p>

<p>For our authentication, we will make use of <a href="https://jwt.io/introduction">JWT token</a> . JWT is a standard used to create access tokens for an application.</p>

<p>We will create a file to handle user authentication. To do this, create a folder named <code>auth</code> in your <code>api</code> folder and within it, create a file <code>[...nextauth].js</code> with the following code in it:<br>
</p>

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>    import NextAuth from "next-auth";

<p>The code above sets up our <code>Google Authentication</code> for our app. To use it, we need to wrap up our application in <code>_app.js</code> with the Google Provider component:<br>

<p>Next, we will modify our <code>Displayforum</code> component in to return to our component if the user is authenticated, else it returns a button that leads to an authentication page:<br>

<p>The above code simply returns “logging in” if <code>loadingSession</code> is true. If there is <code>session</code>, we will return the rest of the component and if there is no <code>session</code> we will render a button to <code>sign in</code> to access the app.<br>

<p>To make use of <code>Google authentication</code> in our app, we will require access credentials from Google Cloud console. To get this, navigate in your browser to <a href="https://console.developers.google.com/apis/credentials.">Google Cloud</a>.</p>

<p>Finally, set the redirect URL to: <a href="http://localhost/api/auth/callback/google">http://localhost/api/auth/callback/google</a></p>

<p>To use the credentials in the <code>[…nextauth].js</code>  file, you can create a <code>.env</code> file and set up your environmental variables:<br>
</p>

<div class="highlight js-code-highlight">

<p>Next, we will set up our <code>Uploadforum.js</code> component on our <code>upload</code> page as a protected route so that unauthorized users can’t access the route. To do this, in <code>upload.js</code> add the following code:<br>
</p>

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>    import { getSession, useSession } from 'next-auth/client'

<div class="highlight__panel js-actions-panel">

<p>Then at the bottom:<br>
</p>

<div class="highlight js-code-highlight">

      }
      return {

</svg>

</div>
</div>
</div>



<p>Now, if you run the app with <code>npm run dev</code> in CLI, we have <code>Google authentication</code> implemented. Also we can’t access the <code>/upload</code> path without logging in.</p>

<p>Now that we have added authentication to our app, we can add the <code>username</code> received from the <code>Google Login</code> as the <code>Answername</code> field when we answer a question:<br>

<p>Now, if I add a new answer to the form:</p>

<p>When I click on the <code>Post</code> button, I get:</p>

<p>The answer has been added and the <code>Answername</code>  field has been set to my <code>user.name</code> form our <code>session</code>.</p>

<p>Finally, we will also add the <code>username</code> when posting a question to our <code>collection</code>. We will do this in our <code>upload.js</code> file:<br>

<p>Then we pass the value of <code>session</code> to our <code>Uploadforum</code> Component:<br>
</p>

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>    <Uploadforum session={session} />
</code></pre>
<div class="highlight__panel js-actions-panel">
<div class="highlight__panel-action js-fullscreen-code-action">
    <svg xmlns="http://www.w3.org/2000/svg" width="20px" height="20px" viewbox="0 0 24 24" class="highlight-action crayons-icon highlight-action--fullscreen-on"><title>Enter fullscreen mode</title>

</svg>

</div>
</div>
</div>



<p>We can now use <code>session</code> data in our <code>Uploadforum</code> component:<br>
</p>

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>    function Uploadforum({session}) {
    ...
     const newQuestion = {
          Title: name,
          Questions: description,
          Answers: [""],
          Username: session.user.name,
        };
</code></pre>
<div class="highlight__panel js-actions-panel">
<div class="highlight__panel-action js-fullscreen-code-action">

</svg>

</div>



<p>Any new questions added now take the <code>Username</code> field to be the <code>username</code> received from <code>session</code>.</p>

<p>If we add new answers, since the <code>Answername</code> is a field, it overwrites the previous data and all the <code>answers</code> use the same name. To fix this, we will simply modify our <code>Answers</code> field of type JSON to contain both the answers and the username of the person providing the answers.</p>

<p>Then, we can get this data and display it in our <code>Displayforum</code> component:<br>
</p>

<div class="highlight js-code-highlight">
<pre class="highlight plaintext"><code>     <div className={style.answers}>
                        {response.Answers.map((answers, i) => (

<p><code>answer[0]</code> is the name of the user, while <code>answers[1]</code> is the answer.</p>

<p>Finally, we will modify the code to add new answers:<br>

<p>We can now add new answers to our questions without overwriting previous data.</p>
