You created a Bower component to make your frontend code reusable. You release new updates and you are happy.
You also have Web software project. You release new updates and you are happy.
At some point, you would like to develop your Bower component within the Web project, and release both of them independently and only after the feature is complete.Continue reading
bower link is a powerful but not well advertised feature. I will explain how to use it as part of a real project architecture.
Here is a sample Bower component architecture:
On the other hand, here is how a regular project could be handled, in another place of our computer:
Two Bower components are installed through the
bower install command,
These dependencies are managed as following thanks to the
This is neat but it also means we rely on remote repositories to receive new updates. The only way to receive updates in
my-bower-component is to bump a version upper to
1.33.10 or more). It is suitable for a production use, but what if we want to use a local development version of
my-bower-component at the same time?
The first time I’ve read the
bower link --help documentation, I found the explaination confusing. What is a project? What is some other package?
Well, here it goes.
bower link will register the package as available to be linked. But it will have no other effect anywhere else, yet:
Back to our Web project directory, containing
my-bower-component in the
dependencies part of the
bower.json, we will then type:
Now, your project will benefit from every file change of the
my-bower-component component. Exactly what we wanted.
The project tree structure is now the following:
It simply symlinked the component for us. You may have done that by hand but it provides some extra sugar: the next time you do
bower update, it will wash the symlink away and any version complying with the semver spec as defined in your
bower.json file. Back to the normal.
This is particularly useful for the following use cases:
- prototyping a Bower component before releasing it in the wild (you can link it even if it’s not yet available in the bower registry)
- testing a new feature in a live project
- checking why a component is failing to work as expected despite its unit and functional tests are fine
