<GenerationInfo sourceFile="packages/core/src/cli/populate.ts" sourceLine="51" packageName="@vendure/core" />

Populates the Vendure server with some initial data and (optionally) product data from
a supplied CSV file. The format of the CSV file is described in the section
[Importing Product Data](/current/core/developer-guide/importing-data/).

If the `channelOrToken` argument is provided, all ChannelAware entities (Products, ProductVariants,
Assets, ShippingMethods, PaymentMethods etc.) will be assigned to the specified Channel.
The argument can be either a Channel object or a valid channel `token`.

Internally the `populate()` function does the following:

1. Uses the [Populator](/current/core/reference/typescript-api/import-export/populator#populator) to populate the [InitialData](/current/core/reference/typescript-api/import-export/initial-data#initialdata).
2. If `productsCsvPath` is provided, uses [Importer](/current/core/reference/typescript-api/import-export/importer#importer) to populate Product data.
3. Uses [Populator](/current/core/reference/typescript-api/import-export/populator#populator) to populate collections specified in the [InitialData](/current/core/reference/typescript-api/import-export/initial-data#initialdata).

*Example*

```ts
import { bootstrap } from '@vendure/core';
import { populate } from '@vendure/core/cli';
import { config } from './vendure-config.ts'
import { initialData } from './my-initial-data.ts';

const productsCsvFile = path.join(__dirname, 'path/to/products.csv')

populate(
  () => bootstrap(config),
  initialData,
  productsCsvFile,
)
.then(app => app.close())
.then(
  () => process.exit(0),
  err => {
    console.log(err);
    process.exit(1);
  },
);
```
