JSX element implicitly has type 'any' because no interface 'JSX.X' exists.

Production Risk

Build will fail; resolve before shipping.

What this means

A strict mode error (TS7026): JSX element implicitly has type 'any' because no interface 'JSX.X' exists.. This diagnostic is emitted by the TypeScript compiler when jSX element implicitly has type 'any' because no interface 'JSX.X' exists..

Why it happens
  1. 1TypeScript cannot infer the type and defaults to 'any' with --noImplicitAny
  2. 2Missing type annotation or type parameter
How to reproduce

TypeScript compiler reports TS7026 during type checking.

trigger — this will error
trigger — this will error
// Triggers TS7026
// JSX element implicitly has type 'any' because no interface 'JSX.X' exists.

expected output

error TS7026: JSX element implicitly has type 'any' because no interface 'JSX.X' exists.

Fix

Add an explicit type annotation

WHEN When TypeScript cannot infer the type

Add an explicit type annotation
// Before (implicit any)
function process(value) { return value; }
// After (explicit type)
function process(value: string): string { return value; }

Why this works

Adding explicit type annotations removes the implicit 'any' and enables full type checking.

What not to do

✕ Suppress with @ts-ignore instead of fixing the type

ts-ignore hides real type errors and makes refactoring unsafe.
