# no-new-date-in-workflow - ESLint plugin rules

This rule disallows `new Date(...)` and any `Date.*(...)` static-method call directly inside a `createWorkflow` constructor or a `when().then()` callback.

## Severity

`error`. This rule is enabled in the [recommended](https://docs.medusajs.com/resources/lint#recommended) preset.

## What it Targets

This rule targets files in your project's `src/workflows` directory. It reports `new Date(...)` and `Date.*(...)` calls placed directly in a workflow's constructor or in a `when().then()` callback.

The following code is reported by the rule:

```ts title="src/workflows/example.ts"
import {
  createWorkflow,
  WorkflowResponse,
} from "@medusajs/framework/workflows-sdk"

createWorkflow("my-workflow", (input) => {
  const now = new Date()
  return new WorkflowResponse(input)
})
```

Instead, wrap the date in `transform` or compute it inside a step:

```ts title="src/workflows/example.ts"
import {
  createWorkflow,
  transform,
  WorkflowResponse,
} from "@medusajs/framework/workflows-sdk"

createWorkflow("my-workflow", (input) => {
  const now = transform({}, () => new Date())

  return new WorkflowResponse(now)
})
```

## Why it's Important

A workflow's constructor and `when().then()` callbacks run at definition time, not execution time. So, a date created there is fixed when the workflow is registered, not when it runs. Wrap it in `transform` or a `createStep` callback so it evaluates at execution time.

Learn more in the [Data Manipulation in Workflows documentation](https://docs.medusajs.com/learn/fundamentals/workflows/variable-manipulation).

## Fixable

This rule isn't auto-fixable.
