Nuxt Vs Next

Posted on  by admin

Online playground . Prerequisites . Using create-nuxt-app . Manual Installation . Here, you will find information on setting up and running a Nuxt project in 4 steps. You can play with Nuxt online directly on CodeSandbox or StackBlitz:.

node- We recommend you have the latest LTS version installed. A text editor, we recommend VS Codewith the Veturextension or WebStorm .

A terminal, we recommend using VS Code's integrated terminalor WebStorm terminal . To get started quickly, you can use create-nuxt-app . Make sure you have installed yarn, npx (included by default with npm v5.2+) or npm (v6.1+).

It will ask you some questions (name, Nuxt options, UI framework, TypeScript, linter, testing framework, etc).

To find out more about all the options see the create-nuxt-app documentation . Once all questions are answered, it will install all the dependencies.

The next step is to navigate to the project folder and launch it:.

  1. The application is now running on http://localhost:3000 .
  2. Another way to get started with Nuxt is to use CodeSandboxwhich is a great way for quickly playing around with Nuxt and/or sharing your code with other people.
  3. Creating a Nuxt project from scratch only requires one file and one directory.
  4. We will use the terminal to create the directories and files, feel free to create them using your editor of choice.
  5. Create an empty directory with the name of your project and navigate into it:.

Laying Out the Basics

Replace with the name of your project. Create the package.json file:. Fill the content of your package.json with:. scripts define Nuxt commands that will be launched with the command npm run or yarn .

The package.json is like the ID card of your project. It contains all the project dependencies and much more.

If you don't know what the package.json file is, we highly recommend you to have a quick read on the npm documentation . Once the package.json has been created, add nuxt to your project via npm or yarn like so below:.

This command will add nuxt as a dependency to your project and add it to your package.json. The node_modules directory will also be created which is where all your installed packages and dependencies are stored.

A yarn.lock or package-lock.json is also created which ensures a consistent install and compatible dependencies of your packages installed in your project.

Eleventy vs. Astro

Nuxt transforms every *.vue file inside the pages directory as a route for the application.

Create the pages directory in your project:. Then, create an index.vue file in the pages directory:.

It is important that this page is called index.vue as this will be the default home page Nuxt shows when the application opens. Open the index.vue file in your editor and add the following content:.

Run your project by typing one of the following commands below in your terminal:.

  1. The 1st Factor: Popularity

    We use the dev command when running our application in development mode. The application is now running on http://localhost:3000 .

    Open it in your browser by clicking the link in your terminal and you should see the text "Hello World" we copied in the previous step. When launching Nuxt in development mode, it will listen for file changes in most directories, so there is no need to restart the application when e.g.

    adding new pages. When you run the dev command it will create a .nuxt folder. This folder should be ignored from version control.

    You can ignore files by creating a .gitignore file at the root level and adding .nuxt. Create a page named fun.vue in the pages directory. Add a and include a heading with a funny sentence inside.

    Then, go to your browser and see your new page on localhost:3000/fun . Creating a directory named more-fun and putting an index.vue file inside it will give the same result as creating a more-fun.vue file.

    Edit this page on GitHub Updated at Fri, Apr 29, 2022 . In this tutorial, we’ll compare Yarn vs npm — the two most popular package managers.

  2. The 2nd Factor: Community & Resources

    We’ll set them side by side and explore their respective benefits and disadvantages to help you choose which one to use for your projects. Back in the good old days, a simple text editor was enough for developers to create and manage the large part of their projects.

    But since then, the Web has changed drastically. Nowadays, it’s common for even a fairly simple project to have hundreds or thousands of scripts, with complex nested dependencies, which are simply impossible to manage without some kind of automated tool.

  3. 🟢 Vue

    And this is the place where package managers come into play. A package manager is a tool that automatically handles a project’s dependencies in a variety of ways.

    • For example, with the help of a package manager we can install, uninstall, update, and upgrade packages, configure project settings, run scripts, and so on.
    • All the hard and tedious work is done by the package manager, leaving to us only the fun part — the coding itself.
    • npm stands for Node Package Manager. It was released back in 2010, beginning a new era in web development.
    • Until then, the project dependencies were downloaded and managed manually.
  4. Conculsion

    npm was the magic wand that pushed the Web to the next level.

    npm actually involves three things:. a website for managing various aspects of your npm experience. a registry for accessing an extensive public database of JavaScript packages.

    a command-line interface (CLI) for interacting with npm via the terminal. However, when most people talk about npm, they usually mean the last one — the CLI tool.

    It ships as a default package manager with each fresh Node installation. This means you can start using it right away.

  5. Installing the package managers themselves

    If you’d like a deep dive into working with npm, please consult our Node Package Manager Guide.

    Yarn stands for Yet Another Resource Negotiator. The Yarn package manager is an alternative to npm, released by Facebook in October 2016.

The original goal of Yarn was to deal with npm drawbacks, such as performance and security issues.

Yarn was quickly positioned as a safe, fast, and reliable JavaScript dependency management tool. But the npm team learned their lesson and rapidly filled the npm gaps by implementing the missing features.

VuePress vs. Astro

Let’s quickly travel through time to see the big picture:. 2010: npm is released with support for Node.

2016: Yarn is released. It shows much greater performance than npm. It also generate a yarn.lock file that makes sharing and exact replication of repos much easier and predictable.

2017: npm 5 is released. It offers auto-generation of a package-lock.json file in answer to yarn.lock. 2018: npm 6 is released with improved security.

Now npm checks security vulnerabilities before dependencies are installed. 2020: Yarn 2 and npm 7 are released. Both packages come with great new features, as we’ll see later in this tutorial.

2021: Yarn 3 is released with various improvements. Nowadays, both package managers are neck and neck in the package management race, offering similar features and capabilities.

But there are still several differences that help to determine which we choose to use. In the rest of this tutorial, we’ll explore the main similarities and differences between npm and Yarn.

We’ll start our comparison exploration with the installation process for both npm and Yarn.

Yarn vs npm: a Feature Comparison

As I noted above, npm comes preinstalled with Node, so there’s no need to install npm manually.

In contrast, Yarn needs to be installed explicitly. First, we need to install Yarn globally:. Then, we can use it on a per-project basis by setting the desired version inside our project.

We do that by running the yarn set version command in the project’s root directory:. In this case, berry is the version we want to set.

If we want to update to the latest version, we run this:.

  1. The 5th Factor: Real-world examples

    With Yarn we can use a different version for each project. To do the same with npm, you’ll need to have nvm (Node Version Manager) installed.

    Here’s how to install multiple versions of Node using nvm. Now, let’s see how project dependencies are installed.

  2. Set up your project

    When we run npm install, the dependencies are installed sequentially, one after another.

    The output logs in the terminal are informative but a bit hard to read. To install the packages with Yarn, we run the yarn command. Yarn installs packages in parallel, which is one of the reasons it’s quicker than npm.

    If you’re using Yarn 1, you’ll see that the yarn output logs are clean, visually distinguishable and brief.

    They’re also ordered in a tree form for easy comprehension. But this is changed in versions 2 and 3, where the logs aren’t so intuitive and human-readable.

    So far, we’ve seen that npm and Yarn have different commands for installing packages.

    In the next section, we’ll explore more commands. npm and Yarn share many commands, but there are also many non-identical commands.

  3. 🔴 Angular

    Let’s first explore some of the identical commands: . npm init | yarn init: create a new package.

    npm run | yarn run: run a script defined in the package.json. npm test | yarn test: test a package. npm publish | yarn publish: publish a package. npm cache clean | yarn cache clean: remove all data from the cache folder.

    These commands make switching between two managers easy, but there are some non-identical commands that can cause confusion.

    Let’s see what they are in the next list:. npm install | yarn: install dependencies.

  4. Generating a Lock File

    npm install [package] | yarn add [package]: install a package. npm install --save-dev [package] | yarn add - -dev [package]: install a package as a development dependency.

    npm uninstall [package] | yarn remove [package]: uninstall a package. npm uninstall --save-dev [package] | yarn remove [package]: uninstall a development dependency package.

    npm update | yarn upgrade: update the dependencies. npm update [package] | yarn upgrade [package]: update a package.

  5. The 3rd Factor: Performance

    Yarn has also some unique commands which don’t have npm equivalents. For example, the why command displays the reason why a package is needed: it may be a dependency, a native module, or a project dependency.

    Whenever Yarn or npm need to install a package, they carry out a series of tasks. In npm, these tasks are executed per package and sequentially, meaning it will wait for a package to be fully installed before moving on to the next.

    In contrast, Yarn executes these tasks in parallel, increasing performance. While both managers offers caching mechanisms, Yarn seems to do it a bit better. By implementing a zero-install paradigm, as we’ll see in the features comparison section, it’s capable of installing packages almost in no time.

  6. Licenses

    It caches every package and saves it on the disk, so in the next installation of this package you don’t even need to have an internet connection, because the package is installed offline from the disk.

    Even though Yarn has some advantages, the speeds of Yarn and npm, in their last versions, are pretty comparable. So we can’t define a clean winner here.

Manual Installation

One of the main criticisms of npm is regarding security. Previous npm versions have a couple of serious security vulnerabilities. As of version 6, npm audits packages during installation and tells you if any vulnerabilities are found.

We can do this check manually by running npm audit against the installed packages. If any vulnerabilities are found, npm will give us security recommendations.

As you can see in the screenshot above, we can run npm audit fix to fix package vulnerabilities, and the dependency trees will be fixed if it’s possible to do so.

Shopping Cart Page: Static Generation without Data, Combined with Client-side Fetching

SvelteKit vs. Astro

Both Yarn and npm use cryptographic hash algorithms to ensure the integrity of the packages. Just as with commands, some features are shared by npm and Yarn, while there are also some differences.

Let’s first explore the common features these two package managers share. In package.json, the file where both npm and Yarn keep track of the project’s dependencies, version numbers aren’t always exact.

  1. Adding Pages (Fallback)

    Instead, you can define a range of versions. This way, you can choose a specific major and minor version of a package, but allow npm to install the latest patch that might fix some bugs.

    In an ideal world of semantic versioning, patched releases won’t include any breaking changes. But unfortunately, this isn’t always the case.

    The strategy employed by npm may result in two machines ending up with the same package.json file, but having different versions of a package installed — which will possibly introduce bugs.

  2. Using workspaces

    To avoid package version mismatches, an exact installed version is pinned down in a package lock file. Every time a module is added, npm and Yarn create (or update) a package-lock.json and yarn.lock file respectively.

  3. Installing project dependencies

    This way, you can guarantee another machine installs the exact same package, while still having a range of allowed versions defined in package.json. Workspaces allow you to have one monorepo to manage the dependencies across multiple projects.

    This means you have a single, top-level root package that has multiple child packages called workspaces. The npx command is used to run scripts from ./node_modules/.bin.

  4. 🟠 Svelte

    It also allows you to execute packages from the npm registry without installing them in your project dependencies. For example, you can create a new React app by running the following:.

    In Yarn, you can achieve the same result by using the equivalent dlx command:. The rest of the features we’re going to explore are unique to Yarn.

    Zero installs store the cache in your project directory, in a .yarn folder.

  5. Install Nuxt

    When you use commands such as yarn or yarn add , Yarn will create a .pnp.cjs file. This file contains a dependency hierarchy used by Node to load your project packages.

    Thus, you can access them almost at zero time. Plug’n’Play is an alternative installation strategy. Instead of generating a node_modules directory and leaving the resolution to Node, Yarn generates a single .pnp.cjs file that maps packages to their location on the disk and to their list of dependencies.

Incremental Static Generation

  1. Running scripts remotely

    This feature can lead to faster project startup, better optimized dependency tree, faster installation time, and of course removes the need for a node_modules folder.

    Yarn is packed with a built-in license checker that can be useful in different scenarios when you’re developing applications.

  2. Updating Existing Pages (Incremental Static "Re"generation)

    We’ve covered the various similarities and differences of npm and Yarn, but we haven’t established which is better and which one we should choose. As ever, the answer depends on our desires and requirements.

  3. Create your first page

    As a general guide, let me conclude with the following advice:. Choose npm if you’re happy with your current workflow, you don’t want to install an additional tool, and you don’t have a lot of disk space.

  4. Bonus step

    Choose Yarn if you want some great features such as Plug’n’Play, you need some functionality that’s missing in npm, and you have enough disk space.

    If you still find it hard to make a clear decision between npm and Yarn, then you can check pnpm, which tries to combine the best from both package managers and is the third big fish in the package management pool.

    We’ve seen how important package managers are for modern web development, and we’ve compared the two most popular rivals on the market. They both have their advantages and shortcomings, and in order to choose the best for you, you need to have a clear idea of your requirements.

    The best way to decide which is more suitable for you is to try them both and see which performs better. And finally, don’t overthink it. Just choose one and move to the fun part: creating great apps!

Server-side Rendering

1. Install Ganache¶

  1. Plug’n’Play

    Next.js is a React framework that supports pre-rendering. Instead of having the browser render everything from scratch, Next.js can serve pre-rendered HTML in two different ways.

    With Server-side Rendering (SSR), Next.js pre-renders the page into HTML on the server on every request.

    TTFB (Time to first byte) is slower, but your data is always up-to-date. With Static Generation (SSG), Next.js pre-renders the page into HTML on the server ahead of each request, such as at build time.

  2. Per-page Basis

    The HTML can be globally cached by a CDN and served instantly. Static Generation is more performant, but because pre-rendering happens ahead of time, the data could become stale at request time.

    Fortunately, there are ways to work around this issue without rebuilding the entire app when the data is updated.

  3. 🔵 React

    With Next.js, you can use Static Generation for maximum performance without sacrificing the benefits of Server-side Rendering. Incremental Static Generation: Add and update statically pre-rendered pages incrementally after build time.

    Client-side Fetching: Statically generate parts of the page without data, and fetch the data on the client-side. To demonstrate, let’s use a hypothetical e-commerce Next.js app as an example.

    An e-commerce app might have the following pages, each with different data requirements.

  4. Zero installs

    About Us: This page shows the company information, which will be written directly in the app’s source code. No need to fetch data.

    All Products: This page shows the list of all products. The data will be fetched from a database. This page will look the same for all users.

    Individual Product: This page shows each individual product. Like the All Products page, the data will be fetched from a database, and each page will look the same for all users.

Shopping Cart: This page shows a user’s shopping cart.

The data will be fetched from a database. This page will look different for each user. One of my favorite features of Next.js is per-page configuration for pre-rendering.

Prerequisites

  1. Start the project

    You can choose a different data fetching strategy for each page. For our e-commerce app example, we’ll use the following strategy for each page.

    We’ll explain how they work shortly. About Us: Static Generation without data. All Products / Individual Product: Static Generation with data, and then improve upon it using Incremental Static Generation.

  2. The 4th Factor: Learning Curve

    Shopping Cart: Static Generation without data, combined with Client-side Fetching. If a page does not require fetching external data, it will automatically pre-render into HTML at build time.

    This is the default for Next.js pages. Let’s use this for the about page, which has no data requirements. Create a file under the pages directory and export only the component.

  3. Speed Test

    Next, let’s create a page showing all products. We want to fetch from our database at build time, so we’ll use Static Generation. Create a page component that exports a getStaticProps function.

    This function will be called at build time to fetch external data, and the data will be used to pre-render the page component.

All Products Page: Static Generation with Data

Elder.js vs. Astro

getStaticProps is run on our build server (Node.js environment), so the code will not be included in the client-side JavaScript bundle. This means you can directly query your database. Your e-commerce app needs a page for each product with a route based on its id (for example, /products/[id]).

Yarn vs npm: Conclusion

In Next.js, this can be done at build time using dynamic routes and getStaticPaths. By creating a file called products/[id].js and having getStaticPaths return all possible ids, you can pre-render all individual product pages at build time.

E-commerce Next.js App Example

Then, you can fetch data for the individual product from the database. We can use getStaticProps again by providing the id at build time. Now, suppose your e-commerce app has grown significantly. Instead of 100 products, you now have 100,000.


Docusaurus vs. Astro

Products get updated frequently. This poses two problems:. Pre-rendering 100,000 pages at build time can be very slow.

When product data is updated, you’d only want to modify the affected pages. We can't have a full app rebuild every time a product is modified. Both of these problems can be solved by Incremental Static Generation.

Incremental Static Generation allows you to pre-render a subset of pages incrementally after build time. It can be used to add pages or update existing pre-rendered pages.

This allows you to use Static Generation for maximum performance without sacrificing the benefits of Server-side Rendering.
