Config 🚧

vovk.config.{js,cjs,mjs}

The config file is used to define options for the CLI, update template definitions, and customize some other settings. At some cases it’s optional, since the CLI can use default options or flags, but for more advanced usage it’s recommended to create a config file.

Valid config file names

The config can be implemented either as a CJS module or as a ESM module. It supports the following extensions: .js, .cjs, .mjs and can be stored at the root of the project as well as at .config  folder. In other words, the following paths are valid:

  • vovk.config.js
  • vovk.config.cjs
  • vovk.config.mjs
  • .config/vovk.config.js
  • .config/vovk.config.cjs
  • .config/vovk.config.mjs

When vovk init is executed, in order to create proper file name, it checks if the project is a module and, and if the .config folder exists.

Config Options

The config options extend VovkConfig type from vovk package and can be used to define the following options:

emitConfig: boolean | string[]

Indicates whether the config options should be emitted as .vovk-schema/_meta.json file. If set to true, it will emit all options. If set to an array of strings, it will emit only the specified options. Default is ["libs"].

clientTemplateDefs: object

Extends the template definitions with the custom definitions that can be used as fromTemplates field in the composed client or segmented client.

imports: object

Allows to redefine imports used by the generated client, such as fetcher, validateOnClient, and createRPC. The values are paths to the files that export the corresponding functions. Relative paths are resolved from the root of the project, package paths, such as my-lib/fetcher, are rendered as is.

composedClient: object

Redefines config options for the composed client, such as outDir, fromTemplates, excludeSegments, etc.

segmentedClient: object

Redefines config options for the segmented client, such as outDir, fromTemplates, excludeSegments, etc.

Redefines config options for the segmented client, such as outDir, fromTemplates, excludeSegments, etc.

bundle: object

Redefines config options for the bundle, such as excludeSegments, tsdown build options , etc.

modulesDir = 'src/modules'

Indicates the directory where the module files are located. Used to generate modules with vovk new command and to watch for changes in the modules when vovk dev is running.

schemaOutDir = '.vovk-schema'

The directory where the schema is going to be generated. Defaults to .vovk-schema.

origin = ''

The origin for the client, used to generate the client with proper URLs. Defaults to '', meaning that the client will use relative URLs. If you want to use absolute URLs, set it to your domain, e.g. https://example.com.

rootEntry = 'api'

The root entry point for the API routes. By default it’s api, meaning that the API routes will be served from /api path and the segments (route.ts files) are located in the ./src/app/api folder (src/ dir is optional). If you want to serve the API from the root of the domain, set it to an empty string ''. In this case the segments will be located in the ./src/app folder.

rootSegmentModulesDirName = ''

Used exclusively by the vovk new command when multiple segments are used. If set to a non-empty string, the root segment modules will be created in the folder with this name. For example, if it’s set to "root", then when vovk new controller user is executed, the controller will be created at src/modules/root/user/UserController.ts instead of src/modules/user/UserController.ts (the root of the modulesDir)

logLevel = 'info'

Defines the log level  for the CLI. The values are "debug", "info", "warn", "error". By default it’s "info". Set it to "debug" to see underlying operations, such as file watching information.

prettifyClient = false

Wether the generated client code needs to be prettified. Defaults to false. If set to true, the client code will be formatted with Prettier  using your local configuration. It slightly increases the compilation time.

devHttps = false

Progressive Web Apps  require HTTPS protocol to be used both in development and production. In order to enable HTTPS in development you can use --experimental-https flag with next dev command and enable HTTPS mode for vovk dev by setting devHttpsto true or providing --https flag to the command.

/vovk.config.mjs
const config = {
  // ...
  devHttps: true,
};
 
export default config;

If you don’t want to set the HTTPS mode enabled by default, you can create another NPM script that includes the flags:

/package.json
"scripts": {
    "dev-https": "vovk dev --https --next-dev -- --experimental-https",
    "dev": "vovk dev --next-dev",
}

moduleTemplates: object

Record of module template names and their paths. Used by vovk new command to define the templates for the service, controller or any other kind of module. When you have configuration of state template like this:

/vovk.config.mjs
/** @type {import('vovk').VovkConfig} */
const config = {
  // ...
  moduleTemplates: {
    state: './module-templates/State.js.ejs',
    // you can add your own templates here
  },
};

You can create a new module at modulesDir with vovk new state thing command.

npx vovk new state thing # creates src/modules/thing/ThingState.ts file
npx vovk new state segment/thing # creates src/modules/segment/thing/ThingState.ts file

libs: object

The libs object is a conventional way to define configuration for libraries used by the client or any other configuration that you want to expose to the client. For example, it can be used to define localization for vovk ajv.

/vovk.config.mjs
/** @type {import('vovk').VovkConfig} */
const config = {
  // ...
  libs: {
    /** @type {import('vovk-ajv').VovkAjvConfig} */
    ajv: {
      options: {
        strict: false,
      },
      localize: 'en',
    },
  },
};
 
export default config;

If "libs" is present at emitConfig, it will be emitted to the .vovk-schema/_meta.json file and can be accessed multiple ways.

import { schema, UserRPC } from 'vovk-client';
 
console.log(schema.meta.config.libs.ajv.options.strict); // false
console.log(UserRPC.updateUser.fullSchema.meta.config.libs.ajv.localize); // 'en'

segmentConfig: object

To be documented.

openApiMixins: object

Configures OpenAPI Mixins for the client. It allows to define additional OpenAPI operations that can be used in the client. See the OpenAPI Mixins docs for more info.
