Learn Grep, Nuxt and Particle

This course walks you through the steps of creating a News web app using Vue.js and the Nuxt framework. You will learn how to create dynamic pages for each section of your application and load, store, display, filter, and style the data. Then end result will be a News app with multiple category pages, comments for each section, and user pages.

Vue (pronounced /vjuː/, like view) is a progressive framework for building user interfaces. Unlike other monolithic frameworks, Vue is designed from the ground up to be incrementally adoptable. The core library is focused on the view layer only, and is very easy to pick up and integrate with other libraries or existing projects. On the other hand, Vue is also perfectly capable of powering sophisticated Single-Page Applications when used in combination with modern tooling and supporting libraries.

CMD+F in your text editor can only get you so far! In this course, we will learn to use grep and find, two powerful command-line utilities, to search through and explore our codebase. Learn to search specific files and folders, using regular expressions to look for -- or ignore! -- particular phrases. We'll cover how to search recursively, get more context on your results, and some simple tricks to make your searches faster and more targeted.


Once you're familiar with grep and find, you'll be able to quickly answer questions such as: Do I use this function anywhere other than my tests? Where does this file get imported? Whether you're working on a new feature, reading a codebase for the first time, or refactoring existing code, grep and find can help you work faster and more effectively.

A Unix command used to search files for the occurrence of a string of characters that matches a specified pattern.

Use Grep for Fast Search from the Command Line

When you have a bunch of text to sift through, standard Unix command line utilities like `grep`, `sed`, `awk`, `cut`, `sort`, and `uniq` can help extract the information you want. For example, with a git log for a project, you might want to group commits by day in order to see which days you're most productive, or find out how many commits you made last year. In this lesson, you'll learn how to combine these commands with the pipe operator to extract this data from git logs.

In this video you'll learn how to deploy a static Nuxt site to AWS's global edge CDN in less than two minutes. We'll start from scratch, creating a new Nuxt site using npx and walk through the build configuration to set up the deployment target for Jamstack / static site hosting. From there, we'll initialize a new Amplify project using the Amplify CLI and walk through the settings to configure the proper build command for Amplify hosting. Finally, we'll deploy and view the live site. Once we're finished, we'll delete the project and the hosting service.

Deploying a Nuxt Site to AWS with the Amplify CLI

In this video you'll learn how to use Amplify hosting to deploy a Nuxt site from a Git repository. We'll begin by walking through the steps of creating the deployment and configuring the correct build settings to enable a static build. Once the site is deployed, we'll view the live site hosted on AWS.

Sometimes you'll be looking for a string, but won't know which file it's in; or you'll want to find all usages of it within a directory. Learn how to use grep -r to recursively search all the files in a directory. 

Search directory contents recursively using grep

Learn how to use find to identify filenames matching specified patterns. We'll use find to identify all .jsx files in a directory, or all test files in a directory.

Before each page loads, Nuxt supports pre-fetching data to render what you need on the server. This lesson walks you through using Nuxt's `fetch` to load data then save it in the Vuex store.

Learn to use git grep to only search through the tracked files in a git repo. This is especially useful when you want to exclude build artifacts or locally installed dependencies, such as webpack bundles or the node_modules directory. You'll also note that git grep is automatically colorized - we'll see how to get the same coloring effect with grep --color.

Search the contents of a git repository with git grep

By default, grep displays the file path and the line where a match is found. Learn to use the flags -A, -B, -C, and -n to get more context, and view line numbers as well as the lines surrounding a pattern match.


Show context around matches using grep

By using wildcards and glob patterns with the special characters . and *, you can create regular expressions that describe what kind of text you're looking for, instead of just plaintext strings. 

Search for basic patterns using grep

Learn to use grep's extended regular expressions to describe more complex patterns. The `?` and `+` special characters describe optional patterns. The `?` character matches zero or one instance of the preceding term, and the `+` character matches one or more instances of the preceding term. To use these characters, you'll need to either escape them with backslashes or turn on extended regular expressions with the `-E` flag.

Use grep's extended regular expressions to find complex patterns

Learn to use the special anchor characters `^` and `$` to indicate the beginning and end of lines when writing regular expressions for grep. These line anchors are part of basic regular expressions in grep, so you don't need to escape them.

Specify line beginning and end in patterns using grep

You can describe classes of characters using bracket expressions. We'll use expressions such as [a-zA-Z] and [0-9] to search for alphabetic and numeric characters with grep.

The Vue-CLI helps you to quickly and easily setup new Vue projects. Nuxt.js is a library that helps you build server-rendered Vue.js applications. This lesson shows you how to use the nuxt/starter template with the Vue-CLI to quickly start a new project.

Most applications require state to be shared across the application. In the case of Nuxt, you'll share state across pages. Nuxt integrates easily with Vuex by simply adding JavaScript files in the `store` directory. This lesson walks you through setting up a basic store and using it in your template

Manage Vue.js State with Vuex and Nuxt

You commit changes to state in Vuex using defined `mutations`. You can easily access these state mutations in your template using `mapMutations`. This lesson shows you have to wire together your Vue.js template with your Vuex store using mutations and mapMutations.

Describe optional patterns with grep OR using the vertical bar character `|`. By using the `|` special character, you can write either-or style patterns. In this lesson we'll look for matches on "grey" or "gray". Like the `+` and `?` characters, the `|` character is part of extended regular expressions with grep, so you'll either need to escape it with a backslash, or use the -E flag.

You'll notice soon after working with Nuxt that you'll begin to see your styles flash in during each page load. This is due to the development mode of Nuxt where it injects the styles into the page after the initial page render. You can rest assured that when you use `nuxt build`, your styles will render before the page loads.

Understand the Flash of Unstyled Content in Nuxt

Because Nuxt renders pages on the server, you should use the `nuxt-link` components to navigate between pages. Each time a page loads, you can check if you're on the client or server and avoid doing unnecessary loading based on how the page was rendered. This lesson walks you through using `nuxt-link` and `isClient` to navigate and avoid reloading data.

Navigate with nuxt-link and Customize isClient Behavior in Nuxt and Vue.js

You can isolate parts of templates you want to re-use into components, but you can also reuse those components across pages using layouts. This lesson walks you through creation a navigation component then extracting it out into the default layout.
