How to Build Lightning Fast Surveys with Next.js and SurveyJS

This tutorial demonstrates building a fast, SEO-friendly survey website using Next.js and SurveyJS. It assumes basic familiarity with React and Next.js. The complete code is available in the example repository (link omitted as per instructions, but would be included in a real-world output). A deployed version of the website is also available (link omitted).

Next.js, a React framework, simplifies full-stack web development by handling bundling and offering APIs for optimized page rendering. This tutorial utilizes static site generation (SSG) for improved SEO via sitemaps.

SurveyJS, an open-source tool, facilitates survey creation, sharing, and analysis. Its React API integrates seamlessly with Next.js.

Setting Up the Project

Begin by setting up a Next.js application using the CLI:

<code class="language-bash">npx create-next-app@latest</code>

Choose pure JavaScript and the app router during setup. Run the development server:

<code class="language-bash">yarn run dev</code>

Install SurveyJS packages:

<code class="language-bash">yarn add survey-analytics survey-core survey-creator-core survey-creator-react survey-react-ui</code>

Building the Survey Creator

Create a /creator/page.js file to host the survey creator. The Page component simply renders the Creator component:

<code class="language-javascript">export const metadata = { title: "Survey Creator" };

export default function Page() {
  return <creator></creator>;
}</code>

The Creator component utilizes SurveyJS:

<code class="language-javascript">"use client";

import { useEffect, useState } from "react";
import { SurveyCreatorComponent, SurveyCreator } from "survey-creator-react";

export default function Creator() {
  const [creator, setCreator] = useState();

  useEffect(() => {
    setCreator(new SurveyCreator({ showLogicTab: true, showTranslationTab: true }));
  }, []);

  return <div>{creator && <surveycreatorcomponent creator="{creator}"></surveycreatorcomponent>}</div>;
}</code>

The use client directive is crucial for client-side rendering. The useEffect hook initializes the SurveyCreator.

Displaying the Survey

Next, implement dynamic routes for individual surveys using /app/form/[slug]/page.js. generateStaticParams defines the pages to generate:

<code class="language-javascript">export async function generateStaticParams() {
  return surveys.map((x) => ({ slug: x.slug }));
}</code>

generateMetadata provides SEO metadata:

<code class="language-javascript">export async function generateMetadata({ params }) {
  const survey = surveys.find((x) => x.slug === params.slug);
  return { title: survey.survey.title, description: survey.survey.description };
}</code>

The Page component renders the SurveyComponent:

<code class="language-javascript">export default function Page({ params: { slug } }) {
  const survey = surveys.find((x) => x.slug === slug);
  return <surveycomponent surveydata="{survey.survey}"></surveycomponent>;
}</code>

The SurveyComponent uses SurveyJS to display the survey and sends results to /api/submit/route.js using a fetch request. The API route logs the received data (database integration would be added here).

Viewing Results

Create a results page at /results/[slug]/page.js. generateStaticParams filters surveys with results. The Results component uses survey-analytics to visualize the data. Dynamic imports are used to load survey-analytics at runtime to avoid build errors. The component renders visualizations using VisualizationPanel.

Further Development

Future enhancements include authentication and database integration for persistent data storage.
