Transcript

1. Good development and deployment practices with Node.JS @Soulou – CTO and co-founder
2. 1. Don't do things Be lazy!
3. 1. Don't do things Be lazy! 2. Build flexible apps Development and Production are equal
4. 1. Don't do things Be lazy! 2. Build flexible apps Development and Production are equal 3. Efficient deployments ‘‘ Deploy friday 6pm... let's do it! ’’
5. Let's code
6. 1. Init
7. 2. Environment > app.listen(process.env.PORT || 3000)
8. 3. Autoreload $ [sudo] npm install -g supervisor $ supervisor server.js Alternatives: “forever”, “nodemon”
9. 4. Do not commit node_modules $ echo “.node_modules” >> .gitignore Why: native modules
10. 5. Define versions { … “engines”: { “node”: “0.11.x” } … } Why: Repeatability
11. 6. Automatize assets management $ npm install gulp --save OR (but don't start a project with it) – $ npm install grunt --save
12. 6. Automatize assets management var gulp = require("gulp"), stylus = require("gulp-stylus") gulp.task("stylus", function() { return gulp.src("assets/stylesheets/*.styl") .pipe(stylus()) .pipe(gulp.dest('public/styles')); });
13. 6. Automatize assets management var gulp = require("gulp"), stylus = require("gulp-stylus"), prefixer = require(“gulp-autoprefixer”) gulp.task("stylus", function() { return gulp.src("assets/stylesheets/*.styl") .pipe(stylus()) .pipe(prefixer()) .pipe(gulp.dest('public/styles')); });
14. 7. Don't run things by hand gulp.watch(“assets/**/*.styl”, [“stylus”])
15. 8. Use NPM scripts { … “scripts”: { "postinstall": "npm run gulp", "gulp": "gulp stylus", "start": "node index.js" } … }
16. 9. Correctly handle shutdown { … “scripts”: { "postinstall": "npm run gulp", "gulp": "gulp stylus", "start": "node index.js" } … }
17. 10. Deploy many times → One command, nothing else $ git push <dest> <ref> dest: PaaS | Continuous Integration | Your Server
