npm i -g tinybuild
or npm i tinybuild
in local projects.
Please contribute if you are interested in this for your own workflow automation, currently we edit and break and fix this on the basis of our own development so there is absolutely no source control, but we try our best to make it as versatile as possible.

This is the bundler and development server combo you always wanted. Goodbye esoteric instructions, goodbye unwieldy dependencies, and goodbye time wasted staring at your compiler running! Move over Webpack, Parcel, and Vite, there's a new game in town.
- Minimal esbuild bundler wrapper with custom boilerplate and plugins for all of your common javascript or typescript application, server, and library packaging needs. Has inbuilt support for typescript, jsx, and much more.
- Custom esbuild plugins for web workers, streaming imports, types bundling (e.g. for library development), and hotswapping css.
- Pure Nodejs hot reloading test environment with hot module swapping. Only 1 small third party dependency.
- Lightweight automated packaging of native Mobile and Desktop Apps via Capacitor, Electron, or Tauri.
- Bonus Python Quart multithreaded concurrent build and test env examples (not required).
Prerequisites: Latest NodeJS LTS
npm i -g tinybuild
tinybuild
You are ready to develop your applications or libraries!
Modify the tinybuild.config.js and package.json to your needs. You may add build:true
or set server:false
in the config to disable the development server.
Tinybuild also works as a local dependency e.g. npx tinybuild
or executing the packager script via node.js in a custom script. See docs for more details and check out the source code.
The bundler and server presets include a full CLI, config file, or functional (in-script) wrapper for esbuild and server customization, and for creating multiple distributions from a single config (e.g. for browser, esm, node). Bundles and serves complicated libraries and programs in milliseconds with a hot reloading test environment, and makes it easier to scale to production.
In a project folder with a package.json (e.g. after running npm init
for the first time),
Create a tinybuild.config.js
file like so (copy/paste or tinybuild can generate one for you by simply running):
//import {defaultBundler, defaultServer, packager} from 'tinybuild'
const config = {
//build:true, //enable this to skip serve step (same as cli)
//serve:true //or enable this to skip build step (same as cli)
bundler: { //esbuild settings, set false to skip build step or add bundle:true to config object to only bundle (alt methods)
entryPoints: [ //entry point file(s). These can include .js, .mjs, .ts, .jsx, .tsx, or other javascript files. Make sure your entry point is a ts file if you want to generate types
"index.js"
],
outfile: "dist/index", //exit point file, will append .js as well as indicators like .esm.js, .node.js for other build flags
//outdir:'dist' //exit point folder, define for multiple entryPoints
bundleBrowser: true, //create plain js build? Can include globals and init scripts
bundleESM: false, //create esm module js files // { platform:'node' } //etc you can also supply an object here to add more specific esbuild settings
bundleTypes: false, //create .d.ts files, //you need a .tsconfig for this to work, tinybuild will create one for you when you set this true, however, and has typescript support built in
bundleNode: false, //create node platform plain js build, specify platform:'node' to do the rest of the files
bundleHTML: false, //wrap the first entry point file as a plain js script in a boilerplate html file, frontend scripts can be run standalone like a .exe! Server serves this as start page if set to true.
//bundleIIFE:false, //create an iife build, this is compiled temporarily to create the types files and only saved with bundleIIFE:true
//bundleCommonJS:false, //cjs format outputted as .cjs
minify: true,
sourcemap: false,
//plugins:[] //custom esbuild plugins? e.g. esbuild-sass-plugin for scss support
//includeDefaultPlugins:true //true by default, includes the presets for the streaming imports, worker bundling, and auto npm install
//blobWorkers:true, //package workers as blobs or files? blobs are faster but inflate the main package size
//workerBundler:{minifyWhitespace:true} //bundler settings specific to the worker. e.g. apply platform:'node' when bundling node workers, default is minifyWhitespace:true as full minifying may cause unforeseen errors
//globalThis:null //'mymodule'
//globals:{'index.js':['Graph']}
//init:{'index.js':function(bundle) { console.log('prepackaged bundle script!', bundle); }.toString(); }
// outputs:{ //overwrites main config settings for specific use cases

// // external:[] //externals for node environment builds
// },
// //commonjs:{} //bundleCommonJS

export default config;
Then run tinybuild
to supply this to the packager to build and run your project. Customize it to your needs, e.g. for different entry points and use cases. Typescript is automatically recognized, including JSX and TSX. CSS is automatically compiled if you import them in your scripts somewhere. See examples for more.
For using tinybuild locally (npm install
vs npm install -g
) you must import and run packager(config)
from the tinybuild library yourself, and run it in a script file.
Create tinybuild.js at the root of your project directory
import {packager} from 'tinybuild'
import config from './tinybuild.config.js'
packager(config);
then in the console from that project directory run node tinybuild.js
e.g. tinybuild build
or tinybuild serve
to run isolated commands
tinybuild help
lists accepted arguments, see the boilerplate created in the new repo for more. The tinybuild
command will use your edited tinybuild.config.js
or tinybuild.js
(which includes the library and executes the packager with the bundler and/or server itself for more control) config file after initialization so you can use it generically, else see the created package.json
for more local commands.
global command:
tinybuild
-- runs the boilerplate tinybuild bundler + server settings in the current working directory. It will create missing index.js, package.json (with auto npm/yarn install), and tinybuild.js, and serve with watched folders in the working directory (minus node_modules because it slows down) for hot reloading.
local command:
node path/to/tinybuild.js
-- will use the current working directory as reference to run this packager config
start
-- runs the equivalent ofnode tinybuild.js
in the current working directory.build
/bundle
-- runs the esbuild bundler, can specify config withconfig={"bundler":{}}
via a jsonified objectserve
-- runs the node development server, can specify config withconfig={"server":{}}
via a jsonified object and objectmode=python
-- runs the development server as well as python which also serves the dist from a separate port (7000 by default).mode=dev
for the dev server mode (used by default if you just typetinybuild
on boilerplate)path=custom.js
-- target a custom equivalent tinybuild.js entry file (to run the packager or bundler/server)st` - host name for the server, localhost by default
entryPoints=index.js
-- set an entry point for your script, can also be a JSONified array of strings.outfile=dist/index
-- set the output directory and file name (minus the extension name)outdir=dist
-- alternatively use outdir when using multiple entry pointsbundleBrowser=true
-- produce a plain .js bundle that is browser-friendly, true by default.bundleESM=false
-- produce an ESM module bundle, false by default, Will be identified by .esm.jsbundleTypes=false
-- produce .d.ts files, false by default, entry point needs to by a typescript file but it will attempt to generate types for js files in the repo otherwise. The files are organized like your repo in the dist folder used.bundleNode=false
-- create a separate bundle set to include node dependencies. Identified by .node.jsbundleHTML=true
-- bundle an HTML boilerplate that wraps and executes the browser bundle as a quick test. If true the packager command will set this file as the startpage, otherwise you have an index.html you can customize and use that has the same base boilerplate. Find e.g. index.build.html in dist.external=['node-fetch']
-- mark externals in your repo, node-fetch is used in a lot of our work so it's there by default, the node bundle has its own excludes (see our esbuild options in readme)platform=browser
-- the non-node bundles use browser by default, set to node to have all bundles target the node platform. Externals must be set appropriately.globalThis=myCustomBundle
-- You can set any exports on your entry points on the bundleBrowser setting to be accessible as a global variable. Not set by default.globals={[entryPoint]:['myFunction']}
-- you can specify any additional functions, classes, variables etc. exported from your bundle to be installed as globals on the bundleBrowser setting.
host=localhost
-- set the hostname for the server, localhost by default. You can set it to your server url or IP address when serving. Generally use port 80 when serving.port=8080
- port for the server, 8080 by defaultprotocol=http
- http or https? You need ssl cert and key to run httpspython=7000
- port for python server so the node server can send a kill signal, 7000 by default. Run the python server concurrently or usemode=python
hotreload=5000
- hotreload port for the node server, 5000 by defaultwatch=../../path/to/other/src
ORwatch=['path/to/src1','src2','.xml']
- watch extra folders and extensionsextensions=xml,3ds
ORextensions=['xml','3ds']
watch specific extensions for changesignore=../../path/to/other/src,path2/src2

- ignore files and foldersstartpage=index.html
- entry html page for the home '/' page, index.html by defaultcertpath=tinybuild/node_server/ssl/cert.pem
- cert file for httpskeypath=tinybuild/node_server/ssl/key.pem
- key file for httpspwa=tinybuild/pwa/workbox-config.js
- service worker config for pwa using workbox-cli (installed separately via package.json), the server will install a manifest.json in the main folder if not found, https requiredconfig="{"server":{},"bundler":{}}"
-- pass a jsonified config object for the packager. See the bundler and server settings in the docs.init
-- initialize a folder as a new tinybuild repository with the necessary files, you can include the source using the below commandcore=true
-- include the tinybuild source in the new repository with an appropriate package.jsonentry=index.js
--name the entry point file you want to create, defaults to index.jsscript=console.log("Hello%20World!")
-- pass a jsonified and URI-encoded (for spaces etc.) javascript string, defaults to a console.log of Hello World!
electron
-- Start an electron app with boilerplate, copying your dist and specified assets. See Electron Docsmobile={android:'open',ios:false}
-- Use Capacitor to create a bundled mobile app, use 'open' to run android studio or xcode, or set to true to use the CLI, assuming you have dependencies installed. See Capacitor Docs.tauri
-- Alternative minimal desktop runtime via Tauri. See Tauri Docs.assets=['./assets','favicon.ico']
-- Specify additional assets to copy to the native distributions
See README.md files in each subfolder for more explanation on how to work with these types of applications.
If you've installed tinybuild on Mac and it isn't working, try running the following command in the terminal based in this StackOverflow Post:
brew install dos2unix
sudo dos2unix node_modules/tinybuild/tinybuild/bin/global.js
Windows may also throw an error for global package permissions, just copy the error you get into google and use the command line solution you find and you will be good to go.
Feel free to suggest or make changes and report bugs via Issues or direct contact to Joshua Brewster, the entire development system is modular and is a simple automation on top of several simplified development tools. We use this in our daily development workflow so it is battle-tested but on a small sample size.
