Open Source (1998)

Computer software with its source code made available with a license in which the copyright holder provides the rights to study, change, and distribute the software to anyone and for any purpose.

Web-based hosting service

Lets create our open source project

Tech stack: ES6, Webpack, SASS, Jasmine

Lets create our open source project

NPM scriptsThis runs an arbitrary command from a package's "scripts" object.

{ "name": “itweekenddemo",

... "scripts": { "test": "node_modules/.bin/jasmine JASMINE_CONFIG_PATH=jasmine.json", "dev": "node_modules/.bin/webpack-dev-server", "build": "node_modules/.bin/webpack" }, "devDependencies": {

... }}

// run from CLInpm testnpm run devnpm run build

Online Markdown Editor: http://dillinger.io/Update README file

Github pages (gh-pages branch)Public url http://username.github.io/projectname

Gh-pages sync with master

Publish to NPM

// package.json{ "name": “itweekenddemo",

... "version": “0.0.1”,

...}

// run from CLInpm publish

// run from another projectnpm install itweekenddemo —save

Share your package with the world

// insert in your html<script src=“node_modules/itweekenddemo/dist/scroller.bundle.js"></script>

Local NPM package development

// run from CLIcd ~/projects/node-redis # go into the package directorynpm link # creates global linkcd ~/projects/node-bloggy # go into some other package directory.npm link redis # link-install the package

npm list -g --depth=0 # check your link address

Use npm link for this. It will create a globally-installed symbolic link from prefix/package-name to the current folder.

Now, any changes to ~/projects/node-redis will be reflected in ~/projects/node-bloggy/node_modules/node-redis/.

Continuous integration (CI)Is a development practice that requires developers to integrate code into a shared repository several times a day. Each check-in is then verified by an automated build, allowing teams to detect problems early

Travis CI

Travis CI Setup// .travis.ymlinstall: - npm ilanguage: node_jsnode_js: - "4.2.4"script: - npm test - npm run build

Static site generatorsIs a software that takes some text + templates as input and produces html files on the output.Static site generators list: http://www.staticgen.com/

Where to host ?

How to organise ?

Splitting up large codebases into separate independently versioned packages is extremely useful for code sharing. However, making changes across many repositories is messy and difficult to track, and testing across repositories gets complicated really fast.

Projects like Babel, React, Angular, Ember, Meteor, Jest and many others develop all of their packages within a single repository.
