Generates a single .d.ts
bundle containing external module declarations exported from TypeScript module files.
If you have a project with lots of individual TypeScript files that are designed to be consumed as external modules,
the TypeScript compiler doesn’t allow you to actually create a single bundle out of them. This package leverages the
TypeScript language services in TypeScript 1.4+ to generate a single .d.ts
file containing multiple
declare module 'foo'
declarations. This allows you to distribute a single .d.ts
file along with your compiled
JavaScript that users can simply reference from the TypeScript compiler using a /// <reference path />
comment.
.d.ts
generator will also correctly merge non-external-module files, and any already-existing .d.ts
files.
-
npm install dts-generator
-
Generate your
d.ts
bundle:Programmatically:
require('dts-generator').default({ name: 'package-name', project: '/path/to/package-directory', out: 'package-name.d.ts' });
Command-line:
```bash
dts-generator --name package-name --project /path/to/package-directory --out package-name.d.ts
Grunt:
module.exports = function (grunt) {
grunt.loadNpmTasks('dts-generator');
grunt.initConfig({
dtsGenerator: {
options: {
name: 'package-name',
project: '/path/to/package-directory',
out: 'package-name.d.ts'
},
default: {
src: [ '/path/to/package-directory/**/*.ts' ]
}
}
});
};
-
Reference your generated d.ts bundle from somewhere in your consumer module and import away!:
///
import Foo = require('package-name/Foo');
// ...
## Options
* `baseDir?: string`: The base directory for the package being bundled. Any dependencies discovered outside this
directory will be excluded from the bundle. *Note* this is no longer the preferred way to configure `dts-generator`, please see `project`.
* `excludes?: string[]`: A list of glob patterns, relative to `baseDir`, that should be excluded from the bundle. Use
the `--exclude` flag one or more times on the command-line. Defaults to `[ "node_modules/**/*.d.ts" ]`.
* `externs?: string[]`: A list of external module reference paths that should be inserted as reference comments. Use
the `--extern` flag one or more times on the command-line.
* `files: string[]`: A list of files from the baseDir to bundle.
* `eol?: string`: The end-of-line character that should be used when outputting code. Defaults to `os.EOL`.
* `indent?: string`: The character(s) that should be used to indent the declarations in the output. Defaults to `\t`.
* `main?: string`: The module ID that should be used as the exported value of the package’s “main” module.
* `moduleResolution?: ts.ModuleResolutionKind`: The type of module resolution to use when generating the bundle.
* `name: string`: The name of the package. Used to determine the correct exported package name for modules.
* `out: string`: The filename where the generated bundle will be created.
* `project?: string`: The base directory for the project being bundled. It is assumed that this directory contains a `tsconfig.json` which will be parsed to determine the files that should be bundled as well as other configuration information like `target`
* `target?: ts.ScriptTarget`: The target environment for generated code. Defaults to `ts.ScriptTarget.Latest`.
## Known issues
* Output bundle code formatting is not perfect yet
## Thanks
[@fdecampredon](https://github.com/fdecampredon) for the idea to dump output from the compiler emitter back into the compiler parser instead of trying to
figure out how to influence the code emitter.
