Quick JSON

Fast JSON snippets with optional dynamic count support for API mocking.
Static by default for speed. Dynamic only when explicitly requested.


✨ Why QuickJSON?

Most JSON generators are slow because they always process data.
QuickJSON is different:

  • ⚡ Instant static snippets for common use
  • 🧠 Dynamic processing only when you ask
  • 🔒 Controlled keys only (no accidental commands)
  • 🧪 Perfect for frontend & API mocking

🚀 Features

1️⃣ Static JSON Snippets (Fastest)

Uses VS Code snippets — no extension logic, no delay.

Type → press Tab

userjson
postsjson
productjson
cartjson
quotesjson
photojson
countries

➡ Instantly inserts static JSON (default 10 items)


2️⃣ Dynamic Count (Only When Needed)

Triggers extension logic only if :<count> is used

userjson:10
postsjson:50
productjson:100

➡ Reads predefined data
➡ Slices or repeats to match the count
➡ Runs only on demand


3️⃣ Safe & Controlled Commands

Only predefined keys are allowed:

user
posts
product
cart
quotes
photo

❌ Invalid commands are blocked:

boyjson:10
humanjson:20

➡ Prevents mistakes and unexpected behavior


🧠 How It Works (Simple)

Input Handler Performance
userjson Snippet ⚡ Ultra fast
postsjson Snippet ⚡ Ultra fast
userjson:10 Extension logic 🧠 On demand
userjson:100 Extension logic 🧠 On demand

Static first. Dynamic only when required.


🧪 Usage

  1. Open any .json file
  2. Type a command:
    userjson
    
  3. Press Tab

OR

userjson:10

Press Enter


📦 Use Cases

  • Frontend UI development
  • API response mocking
  • Pagination testing
  • Demo data for projects
  • Learning & tutorials

⚙️ Performance Philosophy

QuickJSON is designed to be performance-first:

  • ❌ No unnecessary file reads
  • ❌ No background processing
  • ❌ No auto execution
  • ✅ Explicit user intent only

🛣️ Roadmap (Planned)

  • Custom default count setting
  • Autocomplete for allowed keys
  • Range support (postsjson:10-20)
  • Workspace-level data overrides
