Update multiple dependencies with Bower

Question

I listed (and/or installed) several dependencies with Bower inside the bower.json file and/or with

bower install https://github.com/username/project.git 

That worked fine.

Now I can list all them with

bower list 

and then I can pick the name of each dependency of my project and run

bower update dependency-name 

Question: How can I bulk update all of them? Or do I have to write a shell script to loop through and update them?

Answer 1

You can update all by running bower update.

Use the -h flag on any command to see how you can use it. Eg bower update -h.

Answer 2

This process is a little slow but is secure because you can realize when your app gets broken.

lets say that you want to update bootstrap you just need to run bower install --save bootstrap and you bower.json file will be updated

Before

 {    "name": "my-awesome-app",    "version": "0.0.0",    "dependencies": {      "bootstrap": "~3.0.0",      "requirejs": "~2.1.11",      "modernizr": "~2.8.2",      "jquery": "~2.1.1",      "underscore-amd": "~1.5.2",      "backbone-amd": "~1.1.0",                                                                                                                                                      "require-handlebars-plugin": "~0.8.0"    }  } 

After

 {    "name": "my-awesome-app",    "version": "0.0.0",    "dependencies": {      "bootstrap": "~3.3.1",      "requirejs": "~2.1.11",      "modernizr": "~2.8.2",      "jquery": "~2.1.1",      "underscore-amd": "~1.5.2",      "backbone-amd": "~1.1.0",                                                                                                                                                      "require-handlebars-plugin": "~0.8.0"    }  }
