Migrating ​

While we try to avoid breaking changes, sometimes it's unavoidable in order to offer you the latest features. This page lists changes that require updates to your code.

@next ​

These changes haven't been released yet. However, you can migrate your code today to save time on migration once they're released.

Deprecated exports from index.ts ​

Currently, index.ts file exports all generated artifacts.

ts
export { ApiError } from './core/ApiError';
export { CancelablePromise, CancelError } from './core/CancelablePromise';
export { OpenAPI, type OpenAPIConfig } from './core/OpenAPI';
export * from './models';
export * from './schemas';
export * from './services';

We will be slowly moving away from this practice. Any non-core related imports should be imported as

ts
import type { Model } from 'client/models';
import { $Schema } from 'client/schemas';
import { DefaultService } from 'client/services';

You don't have to update imports from core directory. These will be addressed in later releases.

Deprecated useOptions ​

This config option is deprecated and will be removed.

Deprecated postfixServices ​

This config option is deprecated and will be removed.

Deprecated request ​

This config option is deprecated and will be removed.

Deprecated name ​

This config option is deprecated and will be removed.

v0.38.0 ​

Renamed write ​

This config option is now called dryRun (file) or --dry-run (CLI). To restore existing functionality, invert the value, ie. write: true is dryRun: false and write: false is dryRun: true.

v0.36.0 ​

JSON Schema 2020-12 ​

Schemas are exported directly from OpenAPI specification. This means your schemas might change depending on which OpenAPI version you're using. If this release caused a field to be removed, consult the JSON Schema documentation on how to obtain the same value from JSON Schema (eg. required properties).

Renamed exportSchemas ​

This config option is now called schemas.

v0.35.0 ​

Removed postfixModels ​

This config option has been removed.

v0.34.0 ​

Single services.ts file ​

Services are now exported from a single file. If you used imports from individual service files, these will need to be updated to refer to the single services.ts file.

v0.31.1 ​

Merged enums options ​

useLegacyEnums config option is now enums: 'typescript' and existing enums: true option is now enums: 'javascript'.

v0.31.0 ​

Single models.ts file ​

TypeScript interfaces are now exported from a single file. If you used imports from individual model files, these will need to be updated to refer to the single models.ts file.

Single schemas.ts file ​

Schemas are now exported from a single file. If you used imports from individual schema files, these will need to be updated to refer to the single schemas.ts file.

v0.27.38 ​

useOptions: true ​

By default, generated clients will use a single object argument to pass values to API calls. This is a significant change from the previous default of unspecified array of arguments. If migrating your application in one go isn't feasible, we recommend deprecating your old client and generating a new client.

ts
import { DefaultService } from 'client/services' // <-- old client with array arguments

import { DefaultService } from 'client_v2/services' // <-- new client with options argument

This way, you can gradually switch over to the new syntax as you update parts of your code. Once you've removed all instances of client imports, you can safely delete the old client folder and find and replace all client_v2 calls to client.

v0.27.36 ​

exportSchemas: true ​

By default, we will create schemas from your OpenAPI specification. Use exportSchemas: false to preserve the old behavior.

v0.27.32 ​

Renamed Config interface ​

This interface is now called UserConfig.

v0.27.29 ​

Renamed openapi CLI command ​

This command is now called openapi-ts.

v0.27.26 ​

Removed indent ​

This config option has been removed. Use a code formatter to modify the generated files code style according to your preferences.

v0.27.24 ​

Removed useUnionTypes ​

This config option has been removed. Generated types will behave the same as useUnionTypes: true before.

OpenAPI TypeScript Codegen ​

openapi-ts was originally forked from Ferdi Koomen's openapi-typescript-codegen. Therefore, we want you to be able to migrate your openapi-typescript-codegen projects. Migration should be relatively straightforward if you follow the release notes on this page. If you run into an issue with migration, please open an issue.
