@eddeee888/gcg-typescript-resolver-files

This GraphQL Code Generator plugin creates resolvers given GraphQL schema.

This relies on types generated from @graphql-codegen/typescript-resolvers plugin.

yarn add -D @eddeee888/gcg-typescript-resolver-files

Features

Follows opinionated folder/file structure with type-safety in mind to help finding query, mutation or object types easily
Will not overwrite existing logic
Detects missing / wrong resolver exports and adds them to generated resolvers
Handles GraphQL Scalars with types and config from graphql-scalars

Example

schema: '**/*.graphqls'
generates:
  src/graphql/resolvers/types.generated.ts:
    plugins:
      - typescript
      - typescript-resolvers

  src/graphql/resolvers:
    preset: '@eddeee888/gcg-typescript-resolver-files'
    presetConfig:
      resolverTypesPath: ./types.generated.ts

Config

Name	Type	Description
`resolverTypesPath`	`string`	(Required) Relative path to type file generated by `typescript-resolvers` plugin.
`mode`	`merged` or `modules`	(Default: `modules`) How files are collocated. `modules` detects containing dir of a schema file as "modules", then split resolvers into those modules. `merged` treats `baseOutputDir` as the one and only module and generates resolvers.
`relativeTargetDir`	`string`	Relative path to target dir. For `config.mode=merged`, files will be generated into `<baseOutputDir>/<relativeTargetDir>`. For `config.mode=modules`, files will be generated into `<baseOutputDir>/<moduleName>/<relativeTargetDir>`
`mainFile`	`string`	File that puts all generated resolvers together. Relative from `baseOutputDir`
`whitelistedModules`	`Array<string>`	(Only works with `config.mode=modules`) Whitelists modules to generate files and main file for. Useful for gradual migrations.
`externalResolvers`	`Record<string, string>`	Map of relative or absolute path (prefixed with `~`) to external or existing resolvers. e.g. `DateTime: ~graphql-scalars#DateTimeResolver`, `Query.me: '~@org/meResolver#default as meResolver'`, `User: 'otherResolvers#User as UserResolver'`.
`typescriptPluginConfig`	`(@graphql-codegen/typescript).TypeScriptPluginConfig`	typescript config to override the defaults
`typescriptResolversPluginConfig`	`(@graphql-codegen/typescript-resolvers).TypeScriptResolversPluginConfig`	typescript-resolvers config to override the defaults
