Custom Snippets: Speed up your development

February 17, 2024 - 5 min read

Hello humans!

Custom snippets are a great way to speed up your development. They let you make templates for code you use a lot, so you can add them quickly with a command.

In this article, I will give you my VsCode custom snippets for React and Storybook that you can copy and adapt.

(Reminder) How to create a custom snippet in VsCode ?

Open VsCode
Open the command palette (Ctrl + Shift + P)
Type "snippet" and select "Preferences: Configure User Snippets"
Select "New Global Snippets file"
Name it "custom-snippets"
You are now ready to add your custom snippets between the curly braces

If you miss my previous article about how to create a specific custom snippet, you can find it here.

1. Snippet: Create a React Functional Component


_15"Create a React Function Component": {
_15    "scope": "typescriptreact",
_15    "prefix": "!rc",
_15    "body": [
_15      "import React from \"react\";",
_15      "",
_15      "interface ${TM_FILENAME_BASE/(.*)/${1:/pascalcase}/}Props {}",
_15      "",
_15      "export const ${TM_FILENAME_BASE/(.*)/${1:/pascalcase}/} = ({}: ${TM_FILENAME_BASE/(.*)/${1:/pascalcase}/}Props) => {",
_15      "\treturn <></>;",
_15      "};",
_15      ""
_15    ],
_15    "description": "Create a React Functional Component"
_15  }

${TM_FILENAME_BASE/(.*)/${1:/pascalcase}/}: This retrieves the file name, converts it to PascalCase, and applies it as the component name.

2. Snippet: Create a React useState hook


_10"Create a React useState hook": {
_10    "scope": "typescriptreact",
_10    "prefix": "!rs",
_10    "body": [
_10      "const [${1:state}, set${1/(.*)/${1:/pascalcase}/}] = useState(${2:initialState});"
_10    ],
_10    "description": "Create a React useState hook"
_10}

${1:state}: This, captures developer input, defaulting to 'state' if none is provided.
${1/(.*)/${1:/pascalcase}/}: This will convert the input to PascalCase when user will press tab.

3. Snippet: Create a React useEffect hook


_10"Create a React useEffect hook": {
_10    "scope": "typescriptreact",
_10    "prefix": "!re",
_10    "body": [
_10      "useEffect(() => {",
_10      "",
_10      "}, [${21}]);"
_10    ],
_10    "description": "Create a React useEffect hook"
_10}

4. Snippet: Create a Story for storybook


_21"Create a Story": {
_21    "scope": "javascript,typescript,typescriptreact,javascriptreact",
_21    "prefix": "!story",
_21    "body": [
_21      "import type { Meta, StoryObj } from '@storybook/react';",
_21      "import { ${TM_FILENAME_BASE/(.*).stories/${1:/pascalcase}/} } from './${TM_FILENAME_BASE/(.*)\\.stories/${1}/}';",
_21      "",
_21      "const meta: Meta<typeof ${TM_FILENAME_BASE/(.*).stories/${1:/pascalcase}/}> = {",
_21      "   title: '${1}',",
_21      "   component: ${TM_FILENAME_BASE/(.*).stories/${1:/pascalcase}/},",
_21      "   tags: ['autodocs']",
_21      "};",
_21      "",
_21      "export default meta;",
_21      "",
_21      "type Story = StoryObj<typeof ${TM_FILENAME_BASE/(.*).stories/${1:/pascalcase}/}>;",
_21      "",
_21      "export const Default: Story = {};"
_21    ],
_21    "description": "Create a story template for StoryBook"
_21}

Conclusion

I hope you find these snippets useful. They have saved me a lot of time and I hope they will do the same for you.
