The 'jsxFragmentFactory' compiler option must be provided to use JSX fragment...

Production Risk

Build will fail; resolve before shipping.

What this means

A TypeScript diagnostic (TS17016): The 'jsxFragmentFactory' compiler option must be provided to use JSX fragments with the 'jsxFactory' compiler option.. This diagnostic is emitted by the TypeScript compiler when the 'jsxFragmentFactory' compiler option must be provided to use JSX fragments with the 'jsxFactory' compiler option..

Why it happens
  1. 1JSX syntax used without enabling '--jsx' compiler option
  2. 2Missing React or JSX runtime import
How to reproduce

TypeScript compiler reports TS17016 during type checking.

trigger — this will error
trigger — this will error
// Triggers TS17016
// The 'jsxFragmentFactory' compiler option must be provided to use JSX fragments with the 'jsxFactory' compiler option.

expected output

error TS17016: The 'jsxFragmentFactory' compiler option must be provided to use JSX fragments with the 'jsxFactory' compiler option.

Fix

Enable JSX in tsconfig.json

WHEN Using JSX syntax in TypeScript files

Enable JSX in tsconfig.json
// tsconfig.json
{
  "compilerOptions": {
    "jsx": "react-jsx"  // or "react", "preserve", etc.
  }
}

Why this works

The '--jsx' option tells TypeScript how to transform JSX; choose 'react-jsx' for React 17+ or 'react' for older versions.
