ctix - Next generation Create TypeScript Index file

Installation

npm i ctix --save-dev

Usage

ctix create -p ./tsconfig.json

Introduction

You have to create a list of files when bundling with webpack and rollup.js, or creating documents with typedoc. It's boring to re-list files every time they change files change. ctix is a simple tool that automates the creation of file lists.

Why ctix?

An application project has a clear entry point, but if it is a library project, the entry point is not clear, so you have to create it yourself. typedoc have to explicitly specify what to document, even for an application project.

use TypeScript compiler API
create index.ts file by separating default export and export
support isolatedModules option
various ignore options such as gitignore, npmignore, citignore

Important

ctix does not work in JavaScript code because it uses TypeScript API, please use it before Babel translation or TypeScript compilation.

How to works?

ctix use TypeScript Compiler API and directory structure. Export something from TypeScript source file after run ctix to create index.ts file. Detail working see here

Use ctix with Non TypeScript files

Fonts

webpack, rollup.js bundling fonts like that. You can create .d.ts file and include it.

// @types/DeclareTtfModule.d.ts
declare module '*.ttf';

// fonts/fonts.ts
/// <reference path="../@types/DeclareTtfModule.d.ts" />
import Friend from 'Friend.ttf';
import AlsoFriend from './fonts/AlsoFriend.ttf';

export { Friend, AlsoFriend };

Vue.js

If you use vue.js framework, you can use it as follows.

// @types/vue.d.ts
declare module '*.vue' {
  import Vue from 'vue';
  export default Vue;
}

// components/vue-components.ts
/// <reference path="../@types/vue.d.ts" />
import Foo from 'Foo.vue';
import Bar from './Bar.vue';

export { Foo, Bar };

Pros & Cons

Pros

pass tsconfig.json file, another process don't care about
Support default exportation
- using TypeScript API so detect default export and named export
- my_default_index.test.ts file create export { default as myDefaultIndexTest } from './my_default_index.test.ts'
Partial ignore
- specific export statement exclude on index.ts file.
- eg. { "my_lib_package.ts": ["exists", "temp"] }
Skip empty directory
isolatedModules support

Cons

It may be slow for some project
- since ctix uses TypeScript compiler API, big projects may take time to generate index files

What is difference Re-Map paths?

It is not recommended to use index.ts file to re-map paths or shorten the paths. If you want to shorten the paths use Re-Map paths feature in TypeScript compilerOptions. ctix is recommended for webpack and rollup.js, typedoc entrypoint and TypeScript declaration file bundling.

Option

Name	Short	Default	Command	Description
--config	-c		All	configuration file(.ctirc) path
--project	-p	required	All	tsconfig.json path: you must pass path with filename, like this "./tsconfig.json"
--spinnerStream		stdout	All	Stream of cli spinner, you can pass stdout or stderr
--progressStream		stdout	All	Stream of cli progress, you can pass stdout or stderr
--reasonerStream		stderr	All	Stream of cli reasoner. Reasoner show name conflict error and already exist index.ts file error. You can pass stdout or stderr
--startAt	-a	= --project	All	start working from startAt directory. If you do not pass startAt use project directory.
--exportFilename	-f	index.ts	create, single, remove	Export filename, if you not pass this field that use "index.ts" or "index.d.ts"
--useSemicolon	-s	true	create, single	add semicolon on line ending at every export statement
--useTimestamp	-t	false	create, single	timestamp write on ctix comment right-side, only works in useComment option set true
--useComment	-m	true	create, single	ctix comment add on first line of created export file(default index.ts) file, that remark created from ctix
--quote	-q	'	create, single	change quote character at export syntax
--keepFileExt	-k	'	create, single	keep file extension on export statement path literal
--overwrite	-w	'	create, single	overwrite each index.ts file
--ignoreFile	-g		create, single	ignore file name. You can pass ignore, config file at ctix and use it like profile
--noBackup		false	create, single	not create backup file even if set overwrite option enable
--skipEmptyDir	-e	'	create	empty directory skip create index.ts file
--output	-o	N/A	single	output directory
--useRootDir	-r	false	single	output file under rootDir in tsconfig.json.
--includeBackup	-b	false	remove	If this option set true on remove mode what will be delete backup file.

Ignore

Ignore file 3 way belows:

.gitignore
.npmignore
.ctiignore

.gitignore file follow .gitignore spec 2.22.1. .ctiignore file key follow .gitignore spec 2.22.1. .gitignore spec 2.22. spec using by ignore package. .npmignore spec using by minimatch

.ctiignore

.ctiignore file is json with comments. See below.

{
  "juvenile/**": "*",
  "wellmade/FlakyCls.ts": "*",
  "wellmade/WhisperingCls.ts": "*",
  "wellmade/ChildlikeCls.ts": ["transfer", "stomach"]
}

json key indicate ignore file path. You can use glob pattern like .gitignore. If set '*' character at value that is totally ignore file or glob pattern. If set string array that is ignore type name array.

Partial Ignore glob pattern (higher v1.6.x)

You can use glob pattern in partial ignore like that. Partial ignore follow .gitignore spec 2.22.1.

{
  "case00?.ts": ["*Case00*"]
}

ignore testcase

testcase directory ignore using glob pattern.

{
  // ignore testcase file
  "**/__tests__/*": "*"
}

The testcase file is ignored if you add to the ignore file or if there is no export syntax.

rootDir, rootDirs

useRootDir option activate using rootDir option in tsconfig.json. This option run below flowchart.

CLI with .ctirc

ctix cli support .ctirc configuration file. Available name is only .ctirc. Also cti cli arguments forced applied. And .ctirc file can write json with comments.

.ctirc creation

You can use cli for .ctirc file creation.

# create current directory
> cti init

# pass tsconfig.json path
> cti init -p ./server/tsconfig.json

Breaking Change

0.6.x and 1.x version big different. See migration guide. cli command, option, ignore file changed. Support TypeScript 4.7.2 and new file extensions(.mts, .cts, etc).

Programming interface

Each command can use that function. Each function can pass isMessageDisplay flag second parameter. isMessageDisplay pass false or undefined after not display console message and progress.

Function	Argument	command
createWritor	TCreateOptionWithDirInfo, isMessageDisplay	create
singleWritor	TSingleOptionWithDirInfo, isMessageDisplay	single
removeIndexFile	TRemoveOptionWithDirInfo, isMessageDisplay	remove
createInitFile	TTInitOptionWithDirInfo, isMessageDisplay	init
