Edit your function
This page will walk you through editing a Binaris function.
If you are new to Binaris it is recommended that you begin with the previous tutorial:
Note: the instructions below assume you are using MacOS, Ubuntu or Debian.
Edit your function
The bn create node8 hello command that you used in the previous getting-started tutorial creates a file called function.js locally.
exports.handler = async (body, context) => {
const name = context.request.query.name || body.name || 'World';
return `Hello ${name}!`;
};
The function receives two arguments. body holds the HTTP request body, and context holds HTTP request and response parameters (such as query strings and headers). Objects returned from a function are automatically JSON-ified and sent as the HTTP response body.
Modify the code
Change the function.js file for the hello function.
- return `Hello ${name}!`;
+ return `Howdy ${name}!`;
After updating the code the function will need to be deployed again.
$ bn deploy hello
Deployed function hello
Invoke with one of:
"bn invoke hello"
"curl -H X-Binaris-Api-Key:$(bn show apiKey) https://run.binaris.com/v2/run/<Your_Account_Number>/hello"
Next, invoke the function to test the changes:
$ bn invoke hello
"Howdy World!"
$ bn invoke hello --data '{"name": "Binaris"}'
"Howdy Binaris!"
Tip
You can use bn --help to see all the available CLI commands.
