We have created our serverless endpoint last week and lets tweak a bit more today by adding some parameters to our endpoint. Lets get started.

We don’t have to modify serverless.yml and lets keep the same way we did before.

events:
      - http:
          path: sample-endpoint
          method: GET

Lets modify the handler.js as we are adding a name parameter to our endpoint and get a different response depending on the input parameter. We will add a conditional statement for our name parameter in our handler.js like this.

if (event.queryStringParameters && event.queryStringParameters.name) {
    return {
      statusCode: 200,
      body: JSON.stringify(
        {
          message: 'Hello' + event.queryStringParameters.name,
          input: event,
        },
        null,
        2
      ),
    };
  }

So this will be our final result of handler.js

'use strict';

module.exports.hello = async (event) => {


  if (event.queryStringParameters && event.queryStringParameters.name) {
    return {
      statusCode: 200,
      body: JSON.stringify(
        {
          message: 'Hello' + event.queryStringParameters.name,
          input: event,
        },
        null,
        2
      ),
    };
  }

  return {
    statusCode: 200,
    body: JSON.stringify(
      {
        message: 'Go Serverless v1.0! Your function executed successfully!',
        input: event,
      },
      null,
      2
    ),
  }
};

Lets deploy our code and see the result.

Lets go to the endpoint from the browser but this time we will add a name parameter at the end of the url like this

?name=Hlaing

As a final result, we will get a response like this.

You can see the result of our name parameter in the json response of message data.

That’s all for today and we have successfully added a new parameter to our endpoint.

As a conclusion note, I have to say we can still do many things through this serverless project. We can also create other method type endpoint like POST. We can also create services like S3 buckets, DBs and so on through serverless.yml and deploying it. But let me stop the article series here as I also intended to get you a starting point to the serverless framework and I think you got it.

See you again . Yuuma

During studying flutter, I learned a beautiful and simple grid system. These interesting and simple grid view layout topics I would like to share you today.

Ever created with a multiple layout with multiple rows within a column?

Try a GridView! While there are multiple GridView constructors, the most common way to create a GridView is the count constructor.

GridView.count(
..
..
)

Start by listing all the items you want in the grid,

GridView.count(
children: [allItems],
)

but it doesn’t end there, control how many items you want to across the grid, by setting the crossAxisCount property.

GridView.count(
crossAxisCount: 1,
children: [allItems],
)

Setting it to 1 makes it look like a normal list. And if your items want to some social distancing? Use mainAxisSpacing gives horizontal space between the rows and crossAxisSpacing provides vertical space between the columns.

GridView.count(
mainAxisSpacing: 28.0,
crossAxisCount: 2,
children: [allItems],
)

Now Let’s make simple grid view using GridView.count constructor.

GridView.count(
  primary: false,
  padding: const EdgeInsets.all(20),
  crossAxisSpacing: 10,
  mainAxisSpacing: 10,
  crossAxisCount: 2,
  children: <Widget>[
    Container(
      padding: const EdgeInsets.all(8),
      child: const Text("He'd have you all unravel at the"),
      color: Colors.teal[100],
    ),
    Container(
      padding: const EdgeInsets.all(8),
      child: const Text('Heed not the rabble'),
      color: Colors.teal[200],
    ),
    Container(
      padding: const EdgeInsets.all(8),
      child: const Text('Sound of screams but the'),
      color: Colors.teal[300],
    ),
    Container(
      padding: const EdgeInsets.all(8),
      child: const Text('Who scream'),
      color: Colors.teal[400],
    ),
    Container(
      padding: const EdgeInsets.all(8),
      child: const Text('Revolution is coming...'),
      color: Colors.teal[500],
    ),
    Container(
      padding: const EdgeInsets.all(8),
      child: const Text('Revolution, they...'),
      color: Colors.teal[600],
    ),
  ],
)

The result is!

I wrote about setting up our severless project and deploying to the AWS last week. Today I will talk about invoking our functions and creating endpoints as I mentioned before. So lets get straight to it.

Function Invoking

Lets invoke our function which means execution of the serverless function. In invoking function, we can invoke either locally or cloud way.

Invoking locally

Go to your project root directory and run this command which invoke our function locally before submitting to the cloud.

sls invoke local --function hello

This will call to hello function and give a response like this.

Invoking Cloud (Cloud execution)

sls invoke --function hello

This will also invoke our function but not from our local code. This will hit our function hello from the cloud and give us a response.

Creating Endpoints

Lets create a simple endpoints first before we tweak a bit more later. Remember the endpoint will be hit up when a specific event will come up which is the main concept of serverless (Event). So if we want to create an endpoint , we also need to create an event.

Go to serverless.yml and find the functions parts and we will add an event and endpoint like this. Please be careful about the indentations as the yml file is sensitive.

functions:
  hello:
    handler: handler.hello
    events:
      - http:
          path: sample-endpoint
          method: GET

We added an endpoint called sample-endpoint which is a GET method type and we have linked our endpoint with the hello function. Now lets deploy our project again.

sls deploy

As a result , we will get a response like this.

You will see that we get an URL under the endpoints section which is the main response result of our function hello. Lets copy that URL and paste it in browser.

Voila ! Our endpoint works successfully. That is all for this week. I will be talking about tweaking our endpoint a bit more in next week.

Thanks for reading. Yuuma
