Generate parameterized node factories from TypeScript source strings

The TypeScript compiler API provides a complete set of methods to create any node known in the TypeScript AST, e.g. createStringLiteral.

This is great for transforming nodes to desired transformation results but tends to be verbose for complex scenarios.

Installation

yarn add -D ts-transform-creator

Usage

// source.ts
import ts from "typescript";
import { tsc } from "ts-transform-creator";

interface HelloWorldProps {
  name: string;
}

const createHelloWorld = tsc<HelloWorldProps>`() => ${props =>
  ts.createStringLiteral("Hello, " + props.name + "!")}`;

// source.ts
import ts from "typescript";

const createHelloWorld = props =>
  ts.createExpressionStatement(
    ts.createCall(
      ts.createPropertyAccess(
        ts.createIdentifier("console"),
        ts.createIdentifier("log")
      ),
      undefined,
      [ts.createStringLiteral("Hello, " + props.name + "World!")]
    )
  );
