create-json-schema-file v0.0.1-beta.2

ts-json-schema-generator

Extended version of https://github.com/xiag-ag/typescript-to-json-schema.

Inspired by YousefED/typescript-json-schema. Here's the differences list:

• this implementation does not use typeChecker.getTypeAtLocation() (so probably it keeps correct type aliases)
• the following features are not supported yet:
  • class types
• processing AST and formatting JSON schema have been split into two independent steps
• not exported types, interfaces, enums are not exposed in the definitions section in the JSON schema

Usage

npm install --save ts-json-schema-generator
./node_modules/.bin/ts-json-schema-generator \
    --path 'my/project/**.*.ts' \
    --type 'My.Type.Full.Name' \
    --expose 'export' \
    --jsDoc 'extended' \
    --strictTuples

Options

-e, --expose <all|none|export>
    all: Create shared $ref definitions for all types.
    none: Do not create shared $ref definitions.
    export:  Create shared $ref definitions only for exported types.

-r, --no-top-ref
    Do not create a top-level $ref definition.

-j, --jsDoc <extended|none|basic>
    basic: Read JsDoc annotations to provide schema properties.
    extended: Also read @nullable, and @asType annotations.
    none: Do not use JsDoc annotations.

-u, --unstable
    Do not sort properties.

-s, --strictTuples
    Do not allow additional items on tuples.

Current state

• interface types
• enum types
• union, tuple, type[] types
• string, boolean, number types
• "value", 123, true, false, null, undefined literals
• type aliases
• generics
• typeof
• keyof

Debug

npm run debug -- test/programs/type-alias-single/main.ts --aliasRefs true MyString

And connect via the debugger protocol.

AST Explorer is amazing for developers of this tool!
