This is a simple utility for concatenating typescript source code into a single file

concat-ts

A simple CLI tool to concatenate exported TypeScript files.

Description

concat-ts is a command-line utility that processes TypeScript files, concatenating them while preserving their export order. It simplifies the process of merging exported TypeScript files into a single output file, making it easier to manage and share code.

Features

Concatenates TypeScript files in topological order based on their exports. Removes import declarations from the output file. Easy to integrate into your build process

Installation

Install concat-ts as a global package:

npm install -g concat-ts

Or, add it as a dependency to your project:

npm install concat-ts --save-dev

Usage

Command Line

concat-ts -i <input_entry_path> -o <output_path>

• -i, --input : Input entry path (required)
• -o, --output : Output path (required)

Programmatically

import { concatTs } from "concat-ts";

concatTs({
  input: "path/to/input/entry.ts",
  output: "path/to/output/file.ts",
});

Example Given the following TypeScript files:

index.ts

export { default as Foo } from "./Foo";
export { default as Bar } from "./Bar";

Foo.ts

export default class Foo {
  // ...
}

Bar.ts

export default class Bar {
  // ...
}

Running the command:

concat-ts -i index.ts -o output.ts

Will produce the following concatenated output file:

output.ts

export default class Foo {
  // ...
}

export default class Bar {
  // ...
}

As you can see this is a simple concat and things such as the default exports will not be fixed. That being said, the files are topologically imported.

Development

dev

npm run dev

Runs the CLI application.

You can pass arguments to your application by running npm run dev -- --your-argument. The extra -- is so that your arguments are passed to your CLI application, and not npm.

clean

npm run clean

Removes any built code and any built executables.

build

npm run build

Cleans, then builds the TypeScript code.

Your built code will be in the ./dist/ directory.

test

npm run test

Cleans, then builds, and tests the built code.

bundle

npm run bundle

Cleans, then builds, then bundles into native executables for Windows, Mac, and Linux.

Your shareable executables will be in the ./exec/ directory.
