    Let’s first quickly go through the market research.

    Understanding Market Research

    Before plunging into the development of a product, it’s important to gain insights into the market landscape. Let’s illustrate this with an example. Suppose you want to create a single-page application for personal fitness tracking:

    • Identify Competitors: Start by identifying existing fitness-tracking web apps like Fitbit, MyFitnessPal, or Strava. These are your direct competitors.
    • Analyze Competitor Offerings: Use these applications and get to know their features. Identify what they do well, and more importantly, where they fall short.
    • User Reviews: User reviews and comments on app stores and social media are often important information. They provide insights into what potential users might expect from your app.

    Identifying Market Trends

    Observing market trends is crucial in the planning phase:

    • Feature Trends: Look for trends or rising demands for certain features in the fitness tracking market. For example, is there an increased interest in diet tracking or sleep quality analysis?
    • Technology Trends: Stay informed about the latest tech trends, such as the growing demand for real-time data tracking or integration with other smart devices.

    Now, let’s understand the target audience.

    Defining Your Target Audience

    Finally, understanding your target audience is important to developing an app that meets their needs:

    • Audience Profile: Consider factors such as age, occupation, interests, and tech-savviness of your audience. For a fitness tracking app, your target audience could be health-conscious individuals, fitness enthusiasts, or people with specific health goals.

What is client-side routing in SPAs?

In a SPA, routing is managed by JavaScript on the client side rather than by a server. This means that when a user clicks a link or a button in the app, the URL changes but the request to the server is not sent. Instead, a new view is loaded into the browser, providing a smoother, faster experience for the user.

What is the difference between traditional multi-page websites and single-page applications?

Traditional multi-page websites require page reloads for each interaction, while SPAs provide a seamless user experience with instant updates and smoother transitions within a single page.
