WIP - add ability to parse indexed access types

[xddq]

• Noticed that indexed access types were not working and implemented a first version of it supporting indexed access types with depth1 and depth2. Was to stupid to implement it with recursion yet, might be a task for another day :p. Main changes in this file here

• Added skeleton for jest tests

How to test

• test index access with "depth 2". Create types.ts with content

// Arbitrary example types

export type Address = {
  street: string;
  test: {
    a: string;
  };
};

export type Address2 = {
  street2: Address["test"]["a"];
};

• run yarn build && yarn start
• expected output

import { Type, Static } from '@sinclair/typebox'

export type Address = Static<typeof Address>
export const Address = Type.Object({
  street: Type.String(),
  test: Type.Object({
    a: Type.String()
  })
})

export type Address2 = Static<typeof Address2>
export const Address2 = Type.Object({
  street2: Type.String()
})

• test index access with "depth 1"
• create types.ts with content

// Arbitrary example types

export type Address = {
  street: string;
  test: {
    a: string;
  };
};

export type Address2 = {
  street2: Address["test"];
};

• run yarn build && yarn start
• expected output

import { Type, Static } from '@sinclair/typebox'

export type Address = Static<typeof Address>
export const Address = Type.Object({
  street: Type.String(),
  test: Type.Object({
    a: Type.String()
  })
})

export type Address2 = Static<typeof Address2>
export const Address2 = Type.Object({
  street2: Type.Object({
    a: Type.String()
  })
})

• dummy tests should pass, run yarn build && yarn test
