Hello Netlify Functions

Goal: Have Netlify recognize a serverless function in their admin panel.

Plan

1. Create a repo with a hello function that does whatever
2. Create a netlify.toml file (that isn't broken), setting the functions folder.
3. Create a Netlify app and deploy from repo
4. Success condition: hello function shows up in Netlify admin.

Brute force notes

• First question in my mind: what should the function do? What's the minimum? Found this code on the Build functions with JavaScript docs page:

  exports.handler = async function(event, context) {
    return {
      statusCode: 200,
      body: JSON.stringify({message: "Hello World"})
    };
  }

• There seems to be a some variation in the docs over how to set up functions with netlify.toml. I'm going by the official docs:

  [functions]
    directory = "functions"
  

• Does npm need to be initialized for netlify functions to work? Answer: nope!

Walk-through

Success: The hello-netlify-functions repo is the minimum you need to publish a Netlify function. - a netlify.toml file is needed to configure the location of the functions directory - Requests to the functions are routed according to this pattern:

    ```
    https://[site-name].netlify.app/.netlify/functions/[function-name]
    ```

    Example:
    
    ```
    https://sait-wbdv-netlify-functions.netlify.app/.netlify/functions/hello
    ```

Next Steps:

• Get this example to work locally with Netlify Dev:

  https://locahost:3000/.netlify/functions/hello
  

• Figure out how to add wildcard redirects for the endpoint so that:

  https://sait-wbdv-netlify-functions.netlify.app/.netlify/functions/hello
  

  maps to

  https://sait-wbdv-netlify-functions.netlify.app/api/hello
  

Optimize

• Nothing needed.
