@sdk-it/core

Low-level TypeScript analysis, OpenAPI reference, schema, and file utilities used by SDK-IT analyzers and generators.

Most applications should start with @sdk-it/cli, @sdk-it/spec, or a language generator. Use @sdk-it/core when building an analyzer or extending the generation pipeline.

Install

npm install @sdk-it/core typescript openapi3-ts

Create a TypeScript program

import { getProgram } from '@sdk-it/core';

const program = getProgram('./tsconfig.json');
const checker = program.getTypeChecker();

for (const sourceFile of program.getSourceFiles()) {
  if (!sourceFile.isDeclarationFile) {
    console.log(sourceFile.fileName);
  }
}

Resolve an OpenAPI reference

import { resolveRef } from '@sdk-it/core';

const schema = resolveRef(openapi, openapi.components!.schemas!.User!);

The root export includes TypeScript program helpers, type derivation, route analysis, OpenAPI reference helpers, and Zod schema evaluation. Lower-level modules are also available through subpaths such as @sdk-it/core/file-system.js and @sdk-it/core/paths.js.
