If you’re a terminal junkie like myself, you are going to love this one. Today we are going to explain how you can avoid writing boilerplate code without any plugins. The feature we are about to explore is called templates or skeletons in Vim.
Skeletons and Vim
Don’t get scared, skeleton files (or templates) are just normal files. They are called that because they will be used as a skeleton when creating a specific file. To create a JSX TypeScript .tsx file, Vim can use a predefined template (skeleton) file and add a React class. How does that look - you must be asking. Let’s see below.
We can define a Skeleton file inside ~/.vim/skeletons/react-typescript.tsx like so:
import React from "react"
interface Props {}
const NewComponent = (props: Props) => {
return (
<>
<div></div>
</>
)
}
export default NewComponent
Then, we can add the following line in our .vimrc:
autocmd BufNewFile *.tsx 0r ~/.vim/skeletons/skeletons/typescript-react.tsx
Let’s break it down a bit:
-
autocmd BufNewFile– run the following when we try to create a new file in Vim -
*.tsx– this is the pattern you want the new file to match -
0r– read into the buffer starting at line 0, the first line -
~/.vim/skeletons/react-typescript.tsx– the file to read into the new file
And, that is it. Every time you create a new React TypeScript file, there will be sitting a new functional component. Let’s see what other useful templates we can use.
Useful Skeletons
I added a couple of skeletons inside my dotfiles on GitHub. Help yourself there and use what you like. I will also share them below.
Bash Script Skeleton
The most common template people suggest is the one for Bash scripts. It can look like this:
#!/usr/bin/env bash
set -eou pipefail
You also need the following line in your .vimrc:
autocmd BufNewFile *.sh 0r ~/.vim/skeletons/skeletons/script.sh
HTML Skeleton
I picked this one up from the HTML boilerplate in 2021.
<!DOCTYPE html>
<html lang="en" class="no-js">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width" />
<title>TODO</title>
<meta name="description" content="Page description" />
<meta property="og:title" content="Unique page title - My Site" />
<meta property="og:description" content="Page description" />
<meta
property="og:image"
content="https://pragmaticpineapple.com.com/image.jpg"
/>
<meta property="og:image:alt" content="Image description" />
<meta property="og:locale" content="en_US" />
<meta property="og:type" content="website" />
<meta name="twitter:card" content="summary_large_image" />
<meta property="og:url" content="https://pragmaticpineapple.com.com/page" />
<link rel="canonical" href="https://pragmaticpineapple.com.com/page" />
<link rel="icon" href="/favicon.ico" />
<link rel="icon" href="/favicon.svg" type="image/svg+xml" />
<link rel="apple-touch-icon" href="/apple-touch-icon.png" />
<link rel="manifest" href="/my.webmanifest" />
<meta name="theme-color" content="#FF00FF" />
</head>
<body></body>
</html>
You can add the next line in the .vimrc to apply HTML boilerplate on the creation of new HTML files:
autocmd BufNewFile *.html 0r ~/.vim/skeletons/skeletons/page.html
Blog Post Markdown Skeleton
The following one is my favorite because I’ve been looking into ways on how to scaffold a new blog post. Take a look:
---
title: TODO
description: TODO
slug: TODO
date: 2021-1-1
published: true
tags:
- TODO
---
I make sure these are only created inside content/blog directories like so:
autocmd BufNewFile *content/blog*.md 0r ~/.vim/skeletons/skeletons/blog-post.md
Where To Keep Skeletons
If the current section was taken out of context, we could have been in trouble. But, jokes aside, where can you store template files? It doesn’t really matter. I keep them inside my dotfiles which I have in version control. They are inside ~/Documents/dotfiles/skeletons. Some folks like them in ~/.vim/templates or ~/.vim/skeletons. I like mine in a dotfiles git repo where I can change and push them to GitHub easily.
Manual Usage
If you are not a fan of Vim automatically populating your files on creation, you can always reach out for the manual approach. To simply fill a file with another file’s content, try out :read command:
:read ~/.vim/skeletons/react-typescript.tsx
The contents of ~/.vim/skeletons/react-typescript.tsx will show below your cursor.
Final Thoughts
That’s all for now. Thanks for tuning in. Consider subscribing to my newsletter, where we will explore the possibility of adding some dynamic templates in one of the next blog posts.
I got the idea to write this blog post from VimTricks in their post, shout out to them.
Also, don’t forget to share with your friends and coworkers on Twitter if you found the post useful.

Until the next one, cheers.
