GitLab supports deployment of functions to AWS Lambda using a combination of:
- [Serverless Framework](https://serverless.com)
- [Serverless Framework with AWS](https://serverless.com/framework/docs/providers/aws/)
- GitLab CI/CD
We have prepared an example with a step-by-step guide to create a simple function and deploy it on AWS.
Additionally, in the [How To section](#how-to), you can read about different use cases,
like:
- Running a function locally.
- Working with secrets.
- Setting up CORS.
Alternatively, you can quickly [create a new project with a template](https://docs.gitlab.com/ee/gitlab-basics/create-project.html#project-templates). The [`Serverless Framework/JS` template](https://gitlab.com/gitlab-org/project-templates/serverless-framework/) already includes all parts described below.

## Example code
## How To
In this section, we show you how to build on the basic example to:
- Run the function locally.
- Set up secret variables.
- Set up CORS.
### Running function locally
The `serverless-offline` plugin allows to run your code locally. To run your code locally:
1. Add the following to your `serverless.yml`:
```yaml
plugins:
- serverless-offline
```
1. Start the service by running the following command:
```shell
serverless offline
```
Running the following `curl` command should trigger your function.
```sh
curl http://localhost:3000/hello
```
It should output:
```json
{
"message": "Your function executed successfully!"
}
```
### Secret variables
Secrets are injected into your functions using environment variables.
By defining variables in the provider section of the `serverless.yml`, you add them to
the environment of the deployed function:
```yaml
provider:
...
environment:
A_VARIABLE: ${env:A_VARIABLE}
```
From there, you can reference them in your functions as well.
Remember to add `A_VARIABLE` to your GitLab CI variables under **Settings > CI/CD > Variables**, and it will get picked up and deployed with your function.
NOTE: **Note:**
Anyone with access to the AWS environemnt may be able to see the values of those
variables persisted in the lambda definition.
### Setting up CORS
If you want to set up a web page that makes calls to your function, like we have done in the [template](https://gitlab.com/gitlab-org/project-templates/serverless-framework/), you need to deal with the Cross-Origin Resource Sharing (CORS).
The quick way to do that is to add the `cors: true` flag to the HTTP endpoint in your `serverless.yml`:
```yaml
functions:
hello:
handler: src/handler.hello
events:
- http: # Rewrite this part to enable CORS
path: hello
method: get
cors: true # <-- CORS here
```
You also need to return CORS specific headers in your function response:
```javascript
'use strict';
module.exports.hello = async event => {
return {
statusCode: 200,
headers: {
// Uncomment the line below if you need access to cookies or authentication
// 'Access-Control-Allow-Credentials': true,
'Access-Control-Allow-Origin': '*'
},
body: JSON.stringify(
{
message: 'Your function executed successfully!'
},
null,
2
),
};
};
```
For more information, see the [Your CORS and API Gateway survival guide](https://serverless.com/blog/cors-api-gateway-survival-guide/)
blog post written by the Serverless Framework team.
### Writing automated tests
The [Serverless Framework](https://gitlab.com/gitlab-org/project-templates/serverless-framework/)
example project shows how to use Jest, Axios, and `serverless-offline` plugin to do
automated testing of both local and deployed serverless function.
## Examples and template
The example code is available:
To see the example code for this example please follow the link below:
- As a [cloneable repository](https://gitlab.com/gitlab-org/serverless/examples/serverless-framework-js).
- In a version with [tests and secret variables](https://gitlab.com/gitlab-org/project-templates/serverless-framework/).

You can also use a [template](https://docs.gitlab.com/ee/gitlab-basics/create-project.html#project-templates)
(based on the version with tests and secret variables) from within the GitLab UI (see
the `Serverless Framework/JS` template).
