+## Tips and Tricks for Angular
+
+### Build with 0 downtime on Angular
+
+The recommended way to have 0 downtime it's using dockerized builds with a docker registry service.
+In case that this isn't possible in your project, here you have a quick fix.
+
+Create this folders on `/dist`:
+
+1. `/dist/previousbuild`
+1. `/dist/nginx` (the new production path)
+
+`package.json` add on `scripts` section:
+```json
+...
+"prebuild": "rm -rf dist/previousbuild",
+"build": "ng build --prod --source-map --optimization=true --buildOptimizer=true --progress=true",
+"postbuild": "mv dist/nginx dist/previousbuild && mv dist/tempbuild dist/nginx",
+...
+```
+
+`angular.json` add on `projects -> *projectname* -> architect -> build -> options`:
+```json
+...
+"outputPath": "dist/tempbuild",
+...
+```
+
+And the result:
+
+1. on build starts, the folder `previousbuild` will be erased
+1. the new build will be created on `tempbuild`
+1. when the new build is done, the previous production build will move to `previousbuild` and the new one will be on
+ `nginx` folder
+1. in case that you need to recover the previous version, you only need rename the two folders

+### npm install
+
+Unlike with PHP `composer install`, the command `npm install` takes `package.json` and resolves the dependencies which means that you might introduce a version different from the one you tested on.
+
+For deploys, CI or initial local environment setup, the **recommended** way to install the dependencies of a project is using `npm ci`.
