This package provides conversion functions between [core-types][core-types-github-url] and [suretype][suretype-github-url].
You probably don't want to use this package directly, but rather [typeconv][typeconv-github-url] which uses this package to convert between TypeScript, JSON Schema, Open API, GraphQL and suretype.
This package converts either from core-types or JSON Schema, when converting to suretype validators. It also converts either to core-types or JSON Schema when converting from suretype.
When converting to and from JSON Schema (rather than core-types), the value constraints are maintained.
It can convert from TypeScript/JavaScript files exporting suretype validators, as long as they are require()able (i.e. have all their dependencies installed).
Other conversion packages:
* [core-types-ts][core-types-ts-github-url]
* [core-types-json-schema][core-types-json-schema-github-url]
* [core-types-graphql][core-types-graphql-github-url]
* Usage
* core-types to suretype
* json-schema to suretype
* suretype to core-types
* suretype to json-schema
There are four conversion functions,
convertCoreTypesToSureType, convertJsonSchemaToSureType converts to suretype,
convertSureTypeToCoreTypes, convertSureTypeToJsonSchema converts from suretype.
These do all return a wrapped value, of the type ConversionResult.
``ts
import { convertCoreTypesToSureType } from 'core-types-suretype'
let doc; // This core-types document comes from somewhere
const { data: tsSourceCode } = convertCoreTypesToSureType( doc, opts );
`
You can provide options as a second argument of the type (it's the same type used for converting from JSON Schema, hence the name):
`ts`
interface JsonSchemaToSuretypeOptions
{
warn?: WarnFunction;
filename?: string;
sourceFilename?: string;
userPackage?: string;
userPackageUrl?: string;
noDisableLintHeader?: boolean;
noDescriptiveHeader?: boolean;
useUnknown?: boolean;
forwardSchema?: boolean;
inlineTypes?: boolean;
exportType?: boolean;
exportSchema?: boolean;
exportValidator?: boolean;
exportEnsurer?: boolean;
exportTypeGuard?: boolean;
unsupported?: 'ignore' | 'warn' | 'error';
}
These options are all optional.
* warn: A function callback to be used for warnings, defaults to console.warn.filename
* The filename to be written to.sourceFilename
This is a hint, no file will be written by the conversion function.
* : The name of the source file from which the core-types comes.userPackage
* : The name of the package using this package.userPackageUrl
* : The url to the package using this package.noDisableLintHeader
* : Prevent writing the "disable linting" comment.noDescriptiveHeader
* : Do no write a top-level descriptive comment about the auto-generated fileuseUnknown
: Use unknown rather than any for any*-types.forwardSchema
* : Forward the JSON Schema, and create an untyped validator schema with the raw JSON Schema under the hood.inlineTypes
* : Inline pretty typescript types aside validator codeexportType
* : Export the deduced types (or the pretty types, depending on inlineTypes)exportSchema
* : Export validator schemasexportValidator
* : Export regular validatorsexportEnsurer
* : Export 'ensurer' validatorsexportTypeGuard
: Export type guards (is validators)unsupported
* : What to do when detecting an unsupported typeignore
* : Ignore (skip) typewarn
* : Ignore type, but warn (default)error
* : Throw an error
The warn function is of type WarnFunction from [core-types][core-types-github-url], meaning it takes a message as string, and an optional second argument of type CoreTypesErrorMeta, also from [core-types][core-types-github-url].
Converting from JSON Schema is almost the same as from core-types;
`ts
import { convertJsonSchemaToSureType } from 'core-types-suretype'
let jsonSchema; // This JSON Schema comes from somewhere
const { data: tsSourceCode } = convertJsonSchemaToSureType( jsonSchema, opts );
`
The opts argument is the same as in convertCoreTypesToSureType.
`ts
import { convertSureTypeToCoreTypes } from 'core-types-suretype'
let sourceCode; // This source code comes from somewhere
const { data: doc } = await convertSureTypeToCoreTypes( sourceCode, opts );
`
An optional second argument can be provided of the type (this is the same type used to convert to JSON Schema, hence the name):
`ts`
interface SuretypeToJsonSchemaOptions
{
warn?: WarnFunction;
filename?: string;
sourceFilename?: string;
userPackage?: string;
userPackageUrl?: string;
refMethod?: 'no-refs' | 'provided' | 'ref-all';
nameConflict?: 'rename' | 'warn' | 'error';
}
* warn: The same warn function as in CoreTypesToGraphqlOptionsfilename
* The filename to be written to.sourceFilename
This is a hint, no file will be written by the conversion function.
* : The name of the source file from which the core-types comes.userPackage
* : The name of the package using this package.userPackageUrl
* : The url to the package using this package.refMethod
* : How to handle references to non-exported typesno-refs
* : Don't ref anything. Inline all types to monolith types.provided
* : Reference types that are explicitly provided.ref-all
* : Ref all provided types and those with names, suretype()'d.nameConflict
* : What to do when detecting a name conflictrename
* : Try to rename typewarn
* : Ignore type, but warnerror
* : Throw an error
`ts
import { convertSureTypeToJsonSchema } from 'core-types-suretype'
let sourceCode; // This source code comes from somewhere
const { data: jsonSchema } = await convertSureTypeToJsonSchema( sourceCode, opts );
`
The optional opts argument is the same as in convertSureTypeToCoreTypes`.
