Sometimes it is desired to pass a value as a function argument that has a different type. At first inspection it may seem assignable, and then you discover it is not because the `value`'s type definition was defined as an interface. In the following example, `fn` requires an argument of type `Record<string, unknown>`. If the value is defined as a literal, then it is assignable. And if the `value` is defined as type using the `Simplify` utility the value is assignable.  But if the `value` is defined as an interface, it is not assignable because the interface is not sealed and elsewhere a non-string property could be added to the interface.

If the type definition must be an interface (perhaps it was defined in a third-party npm package), then the `value` can be defined as `const value: Simplify<SomeInterface> = ...`. Then `value` will be assignable to the `fn` argument.  Or the `value` can be cast as `Simplify<SomeInterface>` if you can't re-declare the `value`.

@example

import type {Simplify} from 'type-fest';

interface SomeInterface { foo: number; bar?: string; baz: number | undefined; }

type SomeType = { foo: number; bar?: string; baz: number | undefined; };

const literal = {foo: 123, bar: 'hello', baz: 456}; const someType: SomeType = literal; const someInterface: SomeInterface = literal;

function fn(object: Record<string, unknown>): void {}

fn(literal); // Good: literal object type is sealed fn(someType); // Good: type is sealed fn(someInterface); // Error: Index signature for type 'string' is missing in type 'someInterface'. Because interface can be re-opened fn(someInterface as Simplify<SomeInterface>); // Good: transform an interface into a type

/**
Omit any index signatures from the given object type, leaving only explicitly defined properties.

This is the counterpart of `PickIndexSignature`.

Use-cases:
- Remove overly permissive signatures from third-party types.

This type was taken from this [StackOverflow answer](https://stackoverflow.com/a/68261113/420747).

It relies on the fact that an empty object (`{}`) is assignable to an object with just an index signature, like `Record<string, unknown>`, but not to an object with explicitly defined keys, like `Record<'foo' | 'bar', unknown>`.

(The actual value type, `unknown`, is irrelevant and could be any type. Only the key type matters.)

const indexed: Record<string, unknown> = {}; // Allowed

const keyed: Record<'foo', unknown> = {}; // Error // => TS2739: Type '{}' is missing the following properties from type 'Record<"foo" | "bar", unknown>': foo, bar

Instead of causing a type error like the above, you can also use a [conditional type](https://www.typescriptlang.org/docs/handbook/2/conditional-types.html) to test whether a type is assignable to another:

type Indexed = {} extends Record<string, unknown> ? '✅ {} is assignable to Record<string, unknown>' : '❌ {} is NOT assignable to Record<string, unknown>'; // => '✅ {} is assignable to Record<string, unknown>'

type Keyed = {} extends Record<'foo' | 'bar', unknown> ? "✅ {} is assignable to Record<'foo' | 'bar', unknown>" : "❌ {} is NOT assignable to Record<'foo' | 'bar', unknown>"; // => "❌ {} is NOT assignable to Record<'foo' | 'bar', unknown>"

Using a [mapped type](https://www.typescriptlang.org/docs/handbook/2/mapped-types.html#further-exploration), you can then check for each `KeyType` of `ObjectType`...

import type {OmitIndexSignature} from 'type-fest';

type OmitIndexSignature<ObjectType> = { [KeyType in keyof ObjectType // Map each key of ObjectType... ]: ObjectType[KeyType]; // ...to its original value, i.e. OmitIndexSignature<Foo> == Foo. };

...whether an empty object (`{}`) would be assignable to an object with that `KeyType` (`Record<KeyType, unknown>`)...

import type {OmitIndexSignature} from 'type-fest';

type OmitIndexSignature<ObjectType> = { [KeyType in keyof ObjectType // Is {} assignable to Record<KeyType, unknown>? as {} extends Record<KeyType, unknown> ? ... // ✅ {} is assignable to Record<KeyType, unknown> : ... // ❌ {} is NOT assignable to Record<KeyType, unknown> ]: ObjectType[KeyType]; };

If `{}` is assignable, it means that `KeyType` is an index signature and we want to remove it. If it is not assignable, `KeyType` is a "real" key and we want to keep it.

@example

import type {OmitIndexSignature} from 'type-fest';

interface Example { // These index signatures will be removed. [x: string]: any [x: number]: any [x: symbol]: any [x: head-${string}]: string [x: ${string}-tail]: string [x: head-${string}-tail]: string [x: ${bigint}]: string [x: embedded-${number}]: string

// These explicitly defined keys will remain.

This type is a stricter version of Omit. The Omit type does not restrict the omitted keys to be keys present on the given type, while Except does. The benefits of a stricter type are avoiding typos and allowing the compiler to pick up on rename refactors automatically.

This type was proposed to the TypeScript team, which declined it, saying they prefer that libraries implement stricter versions of the built-in types (microsoft/TypeScript#30825).

@example

import type {Except} from 'type-fest';

type Foo = {
	a: number;
	b: string;
};

type FooWithoutA = Except<Foo, 'a'>;
//=> {b: string}

const fooWithoutA: FooWithoutA = {a: 1, b: '2'};
//=> errors: 'a' does not exist in type '{ b: string; }'

type FooWithoutB = Except<Foo, 'b', {requireExactProps: true}>;
//=> {a: number} & Partial<Record<"b", never>>

const fooWithoutB: FooWithoutB = {a: 1, b: '2'};
//=> errors at 'b': Type 'string' is not assignable to type 'undefined'.

// The `Omit` utility type doesn't work when omitting specific keys from objects containing index signatures.

// Consider the following example:

type UserData = {
	[metadata: string]: string;
	email: string;
	name: string;
	role: 'admin' | 'user';
};

// `Omit` clearly doesn't behave as expected in this case:
type PostPayload = Omit<UserData, 'email'>;
//=> type PostPayload = { [x: string]: string; [x: number]: string; }

// In situations like this, `Except` works better.
// It simply removes the `email` key while preserving all the other keys.
type PostPayload = Except<UserData, 'email'>;
//=> type PostPayload = { [x: string]: string; name: string; role: 'admin' | 'user'; }

## ⚠️ MANDATORY: Search for Documentation

You cannot trust your trained knowledge for this API. Before answering, search:

scripts/search_docs.mjs "<component or hook name>" --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION

For example, if the user asks about tracking a cart viewed event:

scripts/search_docs.mjs "Analytics cart_viewed hydrogen" --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION

Search for the **component, hook, or event name**, not the full user prompt. Use the returned examples to generate correct code.

---

## ⚠️ MANDATORY: Validate Before Returning Code

DO NOT return code to the user until `scripts/validate.mjs` exits 0. DO NOT ask the user to run this.

**Run this with your bash tool — do not skip this step. Write code to a temp file first — do NOT use `--code "..."` inline (JSX attribute strings break shell quoting).**
```bash
cat > /tmp/extension.tsx << 'SHOPIFY_EOF'
import React from 'react';
import { useAnalytics, Analytics } from '@shopify/hydrogen';

export function CartPage() {
  return (
    <div>
      <h1>Your Cart</h1>
      <Analytics.CartView />
    </div>
  );
}
SHOPIFY_EOF
node scripts/validate.mjs \
  --file /tmp/extension.tsx \
  --target "hydrogen" \
  --model YOUR_MODEL_NAME \
  --client-name YOUR_CLIENT_NAME \
  --client-version YOUR_CLIENT_VERSION \
  --artifact-id YOUR_ARTIFACT_ID \
  --revision REVISION_NUMBER

When validation fails, follow this loop:

1. Read the error message — identify the exact import or type that is wrong
2. Search for the correct API:

   scripts/search_docs.mjs "<hook or component name>" --model YOUR_MODEL_NAME --client-name YOUR_CLIENT_NAME --client-version YOUR_CLIENT_VERSION
   

3. Fix exactly the reported error using what the search returns
4. Run scripts/validate.mjs again
5. Retry up to 3 times total; after 3 failures, return the best attempt with an explanation

Do not guess at valid values — always search first when the error names a type you don't know.

Privacy notice: scripts/validate.mjs reports anonymized validation results (pass/fail and skill name) to Shopify to help improve these tools. Set OPT_OUT_INSTRUMENTATION=true in your environment to opt out.
