TypeScript and TSX builders

The go.osspkg.com/gogen/typescript package builds TypeScript and TSX source from Go. It provides package-level constructors and chainable *Tokens methods, backed by the shared gogen token renderer.

go get go.osspkg.com/gogen/typescript

Build and render TypeScript

Compose declarations from builders, then render the token sequence to an io.Writer:

package main

import (
	"bytes"
	"fmt"

	ts "go.osspkg.com/gogen/typescript"
)

func main() {
	userType := ts.Export().Type().ID("User").Op("=").Block(
		ts.ID("id").Colon().String().Semicolon(),
		ts.ID("name").Colon().String().Semicolon(),
	).Semicolon()
	file := ts.Import("node:fs/promises", ts.ImportNames(ts.ID("readFile"))).Line().Join(userType)

	var source bytes.Buffer
	if err := ts.Render(&source, file); err != nil {
		panic(err)
	}
	fmt.Print(source.String())
}

Output:

import { readFile } from "node:fs/promises";
export type User = {
	id: string;
	name: string;
};

Tokens.Render(w) and typescript.Render(w, token) produce readable token output without formatting, compiling, or type-checking it. Block creates explicit indented layout; nested token sequences do not imply line breaks. Use .ts when the generated file has no JSX.

Build TSX

TSX nodes are structural tokens. The API does not depend on React or another framework. Use JSXText for literal text and JSXExpr for expressions; use the attribute builder that matches the value kind:

package main

import (
	"bytes"
	"fmt"

	"go.osspkg.com/gogen/types"
	ts "go.osspkg.com/gogen/typescript"
)

func main() {
	node := ts.JSXElement(
		ts.ID("button"),
		[]types.Token{
			ts.JSXAttribute("type", "button"),
			ts.JSXAttributeExpr("disabled", ts.ID("isDisabled")),
			ts.JSXSpreadAttribute(ts.ID("props")),
			ts.JSXBooleanAttribute("autoFocus"),
		},
		ts.JSXText("Save "),
		ts.JSXExpr(ts.ID("label")),
	)
	var source bytes.Buffer
	if err := ts.Render(&source, node); err != nil {
		panic(err)
	}
	fmt.Print(source.String())
}

The rendered node is:

<button type="button" disabled={isDisabled} {...props} autoFocus>Save {label}</button>

Use JSXFragment(children...) for a fragment. An element with no children is rendered as self-closing JSX. Text and quoted attribute values are escaped for JSX; expression tokens are rendered inside braces. Write generated code containing JSX to a .tsx file. This package does not run a formatter; invoke TypeScript or Prettier separately when needed.

Builder reference

Builders are available both as package-level functions and as chainable *Tokens methods, except where noted. TemplateText and TemplateExpr return tokens to pass to Template.

Area Builders Notes
Modules Import, ImportType, ImportNames, ImportNamespace, Export, ExportDefault, ExportNames, ExportFrom, From From is fluent-only. Supports side-effect, default, named, namespace, type-only, and re-export declarations. Use ID(name).As().ID(alias) for aliases.
Declarations Const, Let, Var, Function, Type, Interface, Class, Namespace, Async, Await, Return, Throw, Extends, Implements, New, This Compose declarations and common statement keywords. Use Bracket for parameters, Colon for annotations, and Block for bodies.
Class modifiers Public, Private, Protected, Static, Readonly, Abstract, Override, Constructor Compose common class members and constructors.
Control flow If, Else, ElseIf, For, ForOf, ForIn, While, Do, Switch, Case, Default, Break, Continue, Try, Catch, Finally, Of ForOf and ForIn create loops with a const binding.
Expressions ID, Pkg, Raw, Text, Op, Call, Bracket, List, Index, TypeArgs, Selector, OptionalChain, NewCall, KeyValue, Spread, Arrow, As, Optional, NonNull Text creates an escaped string literal; Raw inserts caller-provided source verbatim.
Punctuation Comma, Colon, Semicolon Append the corresponding syntax separators.
Values and types ObjectLiteral, ArrayLiteral, Template, TemplateText, TemplateExpr, Any, Unknown, Never, Void, String, Number, Boolean, BigInt, Symbol, ObjectType, Null, Undefined, True, False, ArrayType, RecordType, MapType, SetType, PromiseType, Union, Intersection Compose object/array values, template strings, primitive and utility types, and unions or intersections.
TSX JSXElement, JSXFragment, JSXAttribute, JSXAttributeExpr, JSXBooleanAttribute, JSXSpreadAttribute, JSXText, JSXExpr Build elements, fragments, attributes, text nodes, and expression children.
Layout and output Block, Comment, Line, Join, Render, Unwrap Set explicit layout, combine token sequences, render source, or access the underlying token slice.

Rendering errors and raw source

Rendering returns errors from the destination writer and from invalid builder input. ID validates identifier syntax, and Op rejects operators outside the adapter's supported set. TSX rendering rejects invalid attribute names, nil tags, nil expressions, and nil children. An element with no children is valid and self-closing.

Raw(source) writes the supplied source verbatim. It does not parse or validate it, so keep raw input under the caller's control. Text(value) emits an escaped JavaScript string literal; JSXText(value) and JSXAttribute(name, value) escape literal values for their JSX contexts.

For the repository overview and other language guides, see the root README, Go guide, and Python guide. The package's exported symbols are also documented on pkg.go.dev.

Overview

Package typescript builds TypeScript and TSX source from composable tokens. Package-level builders create token sequences and fluent methods append to them. Render writes readable token layout without formatting, compiling, or type-checking the output.
