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.tsbundle:Programmatically:
require('dts-generator').default({
name: 'package-name',
project: '/path/to/package-directory',
out: 'package-name.d.ts'
});Command-line:
dts-generator --name package-name --project /path/to/package-directory --out package-name.d.tsGrunt:
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!:
/// <reference path="typings/package-name.d.ts" />
import Foo = require('package-name/Foo');
// ...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 configuredts-generator, it automatically gets its value from compiler optionrootDirif specified intsconfig.json, otherwise it gets value fromproject. Please see optionproject.exclude?: string[]: A list of glob patterns, relative tobaseDir, that should be excluded from the bundle. Use the--excludeflag 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--externflag one or more times on the command-line.types?: string[]: A list of external @types package dependencies that should be inserted as reference comments. Use the--typesflag 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 toos.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 atsconfig.jsonwhich will be parsed to determine the files that should be bundled as well as other configuration information liketargettarget?: ts.ScriptTarget: The target environment for generated code. Defaults tots.ScriptTarget.Latest.resolveModuleId: (params: ResolveModuleIdParams) => string: An optional callback provided by the invoker to customize the declared module ids the output d.ts files. For details see resolving module ids.resolveModuleImport: (params: ResolveModuleImportParams) => string: An optional callback provided by the invoker to customize the imported module ids in the output d.ts files. For details see resolving module ids.
- Output bundle code formatting is not perfect yet
@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.
