= Node.js function template structure
|
|
|
|
When you create a Node.js function using the `kn` CLI, the project directory looks like a typical Node.js project, with the exception of an additional `func.yaml` configuration file.
|
|
|
|
Both `http` and `event` trigger functions have the same template structure:
|

<1> The `func.yaml` configuration file is used to determine the image name and registry.
|
|
<2> Your project must contain an `index.js` file which exports a single function.
|
|
<3> You are not restricted to the dependencies provided in the template `package.json` file. You can add additional dependencies as you would in any other Node.js project.

When the project is built for deployment, these dependencies are included in the created runtime container image.
|
|
<4> Integration and unit test scripts are provided as part of the function template.
