Parses and imports Products using the CSV import format.

Internally it is using the [ImportParser](/current/core/reference/typescript-api/import-export/import-parser#importparser) to parse the CSV file, and then the
[FastImporterService](/current/core/reference/typescript-api/import-export/fast-importer-service#fastimporterservice) and the [AssetImporter](/current/core/reference/typescript-api/import-export/asset-importer#assetimporter) to actually create the resulting
entities in the Vendure database.

```ts title="Signature"
class Importer {
    parseAndImport(input: string | Stream, ctxOrLanguageCode: RequestContext | LanguageCode, reportProgress: boolean = false) => Observable<ImportProgress>;
    importProducts(ctx: RequestContext, rows: ParsedProductWithVariants[], onProgress: OnProgressFn) => Promise<string[]>;
    getFacetValueIds(ctx: RequestContext, facets: ParsedFacet[], languageCode: LanguageCode) => Promise<ID[]>;
    processCustomFieldValues(customFields: { [field: string]: string }, config: CustomFieldConfig[]) => ;
}

### parseAndImport

\<MemberInfo kind="method" type={`(input: string | Stream, ctxOrLanguageCode: <a href='/current/core/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a> | <a href='/current/core/reference/typescript-api/common/language-code#languagecode'>LanguageCode</a>, reportProgress: boolean = false) => Observable<ImportProgress>`}   />

Parses the contents of the [product import CSV file](/current/core/developer-guide/importing-data/#product-import-format) and imports
the resulting Product & ProductVariants, as well as any associated Assets, Facets & FacetValues.

The `ctxOrLanguageCode` argument is used to specify the languageCode to be used when creating the Products.

### importProducts

\<MemberInfo kind="method" type={`(ctx: <a href='/current/core/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, rows: <a href='/current/core/reference/typescript-api/import-export/import-parser#parsedproductwithvariants'>ParsedProductWithVariants</a>[], onProgress: OnProgressFn) => Promise<string[]>`}   />

Imports the products specified in the rows object. Return an array of error messages.

### getFacetValueIds

\<MemberInfo kind="method" type={`(ctx: <a href='/current/core/reference/typescript-api/request/request-context#requestcontext'>RequestContext</a>, facets: <a href='/current/core/reference/typescript-api/import-export/import-parser#parsedfacet'>ParsedFacet</a>[], languageCode: <a href='/current/core/reference/typescript-api/common/language-code#languagecode'>LanguageCode</a>) => Promise<<a href='/current/core/reference/typescript-api/common/id#id'>ID</a>[]>`}   />

### processCustomFieldValues

\<MemberInfo kind="method" type={`(customFields: { [field: string]: string }, config: <a href='/current/core/reference/typescript-api/custom-fields/custom-field-config#customfieldconfig'>CustomFieldConfig</a>[]) => `}   />
