dts-dom is a library for programatically generating TypeScript declaration files.
It is based mostly on the same CodeDOM provided for C# and other .NET languages.
dts-dom automatically handles indentation, formatting, and proper placement of declare and export keywords.
As with other CodeDOM libraries, this is overkill for small projects, but is useful in more complex code generation scenarios.
PRs gladly accepted as this is mostly implemented on an as-needed basis for another project.
npm install --save dts-dom
import * as dom from 'dts-dom';
const intf = dom.create.interface('MyInterface');
intf.jsDocComment = 'This is my nice interface';
intf.members.push(dom.create.method(
'getThing',
[dom.create.parameter('x', dom.type.number)],
dom.type.void,
dom.DeclarationFlags.Optional));
const ns = dom.create.namespace('SomeNamespace');
ns.members.push(intf);
console.log(dom.emit(ns));
This writes out the block:
declare namespace SomeNamespace {
/**
* This is my nice interface
*/
interface MyInterface {
getThing?(x: number): void;
}
}
unknown0 are now correctly printedNew Functionality: Added the ability to emit export default assignments
const module = create.module('my-module');
const constDeclaration = create.const('test', 'string');
const exportDefault = create.exportDefault('test');
module.members.push(constDeclaration, exportDefault);
const s = emit(module);
Produces:
declare module 'my-module' {
const test: string;
export default test;
}
Non-breaking Change: Superfluous declare keywords are no longer emitted inside module declarations
New Functionality: Added the ability to emit triple-slash directives #39
const tripleSlashDirectives = [create.tripleSlashReferenceTypesDirective("react")];
const returnType = create.namedTypeReference('JSX.Element');
const component = create.function('Component', [], returnType, DeclarationFlags.Export);
const s = emit(component, { tripleSlashDirectives });
Produces:
/// <reference types="react" />
export function Component(): JSX.Element;
Breaking Change: Changed the second parameter of emit from ContextFlags to EmitOptions #39
// 1.0
const s = emit(tree, ContextFlags.Module);
// 2.0
const s = emit(tree, { rootFlags: ContextFlags.Module });
The same as 0.1.25
