I am trying rollup js to build my typescript project but I don't know how to generate the definition files and how to include them automatically in the dist files.
Would anyone know how to do it ?
Here is my rollup.config.js
import typescript from "rollup-plugin-typescript";
import handlebars from "rollup-plugin-handlebars";
import babel from 'rollup-plugin-babel';
export default {
entry: 'src/generator.ts',
format: 'cjs',
plugins: [
typescript(),
handlebars(),
babel()
],
dest: 'dist/bundle.js'
};
I'm using the default ts config but that's the same with declaration=true.
edit :
Also trying using Webpack :
module.exports = {
context: __dirname + '/src',
entry: {
index: './generator'
},
output: {
path: __dirname + '/build',
publicPath: '/',
filename: 'generator.js'
},
resolve: {
root: __dirname,
extensions: ['', '.ts', '.js']
},
module: {
loaders: [
{ test: /\.ts$/, loaders: ['ts-loader'], exclude: /node_modules/ },
{ test: /\.hbs/, loaders: ['handlebars-loader'], exclude: /node_modules/ }
]
}
}
Tsconfig :
{
"compilerOptions": {
"target": "es5",
"module": "commonjs",
"declaration": true,
"outDir": "build"
},
"exclude": [
"node_modules",
"dist",
"build"
]
}
The generate d.ts looks like this :
import { ExportPageModel } from './models/page-model';
export declare type ExportType = 'text' | 'html';
export * from './models/page-model';
export declare namespace Generator {
function generateHtml(page: ExportPageModel): string;
function generateText(page: ExportPageModel): string;
}
But in my app using that package, it can't find the Generator...
import { ExportPageModel, Generator } from 'emlb-generator';
Generator is undefined but the auto completion works fine so I can't find where is the problem :(
Generator.generateHtml({
...
});
To do this task you are going to add instructions into rollup.config.js
, tsconfig.json
and package.json
Considering Rollup version ^0.62.0"
:
1 - Add library of rollup-plugin-typescript2
:
npm i rollup-plugin-typescript2
2 - Import the library inside the rollup.config.js
import typescript from 'rollup-plugin-typescript2'
3 - Include the typescript plugin inside the plugin block
Notes: the js bellow is just an example, so I removed other instructions only to keep the example cleaner...
import typescript from 'rollup-plugin-typescript2'
export default {
input: 'src/index.tsx',
output: [
{
file: pkg.main,
format: 'cjs',
exports: 'named',
sourcemap: true
},
{
file: pkg.module,
format: 'es',
exports: 'named',
sourcemap: true
}
],
plugins: [
typescript({
rollupCommonJSResolveHack: false,
clean: true,
})
]
}
4 - Add the declaration
instruction in the compilerOptions
of the tsconfig.json
Notes: I removed other instruction only to keep the example cleaner...
Example:
{
"compilerOptions": {
"declaration": true,
},
"include": ["src"],
"exclude": ["node_modules", "build", "dist", "example", "rollup.config.js"]
}
5 - include the main
and module
instruction inside the package.json
to inform where will be the output.
And finnaly, include the rollup -c
instruction inside the script
of the package.json
, example:
{
"name": "example",
"version": "0.1.6",
"description": "Testing",
"author": "Example",
"license": "AGPL-3.0-or-later",
"main": "dist/index.js",
"module": "dist/index.es.js",
"jsnext:main": "dist/index.es.js",
"scripts": {
"build": "rollup -c",
"start": "rollup -c -w"
},
"files": [
"dist"
]
}
