Inspired by [`YousefED/typescript-json-schema`](https://github.com/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
  * conditional 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

```bash
npm install typescript-to-json-schema
./node_modules/.bin/typescript-to-json-schema \
    --path 'my/project/**.*.ts' \
    --type 'My.Type.Full.Name' \
    --expose 'export' \
    --topRef 'yes' \
    --jsDoc 'extended'
```

## 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](https://astexplorer.net/) is amazing for developers of this tool!

An input argument to this GitHub Action is being exported as an environment variable. If a user of this action passes untrusted input, it could be used in an insecure manner by subsequent workflow steps.

What are GitHub Actions taint flows?

GitHub Actions: Input argument exported as environment variable

An input argument to this GitHub Action is being passed back as an output. If a user of this action passes untrusted input, it could be used in an insecure manner by consuming workflows.

GitHub Actions: Input argument passed back as output

An input argument to this GitHub Action flows into a dangerous sink (such as shell command execution). This could allow a malicious user to inject commands or exploit the action.

GitHub Actions: Input argument flows to dangerous sink

A GitHub context variable (such as issue title, PR description, or comment body) is being exported as an environment variable. These context values are user-controlled and could be exploited by subsequent workflow steps.

A GitHub context variable (such as issue title, PR description, or comment body) is being passed back as an output. These context values are user-controlled and could be exploited by consuming workflows.

GitHub Actions: GitHub context variable passed back as output

A GitHub context variable (such as issue title, PR description, or comment body) flows into a dangerous sink (such as shell command execution). This is a critical security issue that could allow command injection or code execution attacks.

GitHub Actions: GitHub context variable flows to dangerous sink

An environment variable flows into a dangerous sink (such as shell command execution). If this environment variable comes from an untrusted source, it could be exploited to inject commands.
