Typescript Template
This is a library to write formatted TypeScript code using a fluent API.
Here is a simple initialization and usage example:
public class Main {
public static void main(String[] args) {
final TypescriptSource source = new TypescriptSource()
.statement(
new TypescriptNamespaceImport("../address.d.ts")
.selector(new TypescriptImportSelector("Address")),
new TypescriptInterface(
"Person",
new TypescriptInterfaceType("Object")
)
.setComments(new TypescriptComments("Represents a person."))
.field(new TypescriptField("name", TypescriptStringType.INSTANCE, TypescriptField.MANDATORY))
.field(new TypescriptField("age", TypescriptNumberType.INSTANCE, TypescriptField.MANDATORY))
.field(
new TypescriptField("address", new TypescriptInterfaceType("Address"))
.setComments(new TypescriptComments("Address of the person.", "(optional field)"))
)
);
// Pretty print
System.out.println(source.render());
}
}
outputs:
import { Address } from '../address.d.ts';
// Represents a person.
export interface Person extends Object {
name: string;
age: number;
/**
* Address of the person.
* (optional field)
*/
address?: Address;
}
Supported language constructs
- Primitive types (
undefined,null,any,void,boolean,number,string); - Arrays;
- Dictionaries (e.g.
{ [id: string]: IPerson; }); - Generics;
- Union types (e.g.
string | number); - Interface declarations, including inheritance and generic arguments;
- Enum declarations;
- Type aliases declarations;
- Imports;
- Comments (single and multiline);
Some basic static analysis can be performed by visiting the AST:
public class Main {
public static void main(String[] args) {
final TypescriptSource source = ...;
// Print dependencies
System.out.println("Dependencies:");
source.accept(renderable -> {
if (renderable instanceof TypescriptInterfaceType) {
System.out.println(((TypescriptInterfaceType) renderable).getIdentifier());
}
});
}
}
yields:
Dependencies:
Object
Address
