Deploy a puppeteer nodejs application on netlify
Tags: netlify, puppeteer, beginners, tutorial
Published: 2023-02-20 13:30:24

In this article, we’ll learn how we can take advantage of packages like @sparticuz/chromium and Puppeteer-core to create and deploy our puppeteer nodejs application on netlify.

If you are facing issue to run puppeteer on netlify that could be due to the fact that you are using a library called chrome-aws-lambda. And puppeteer core library which is updated very constantly. So it becomes quite a hassle to use chrome-aws-lambda because of the pace of the puppeteer updates. To resolve this issue we could use @sparticuz/chromium library as their docs say that this package is not chained to puppeteer versions.

- Let first create a simple node application.
```js
mkdir puppeteer-node-application
cd puppeteer-node-application
npm init
```
- Now we can also install netlify libraries which will help us to deploy our nodejs application.

```js
npm install netlify-cli -g
```
- Now create a dist folder with empty `index.html` file in it. This is the required netlify configuration.
- Now create a dist folder with empty `index.html` file in it. This is required for netlify configuration.
- Now create a file name `netlify.toml` file and copy the following code in it. This will help netlify recognize where the functions are stored.

```js
[build]
    functions = "functions"
```
- Now create the function directory where we will keep our node puppeteer code. In this directory create a file name `api.js`
- Now lets install puppeteer dependencies to start using puppeteer code in our application

```js
npm install puppeteer-core@19.6.0
npm install serverless-http
npm install @sparticuz/chromium@110
```

> Note: In order to figure out what version of @sparticuz/chromium you will need, please visit [Puppeteer's Chromium Support page](https://pptr.dev/chromium-support).

- Finally copy the following code in the `api.js` file.

{% embed https://gist.github.com/ambujsahu81/9fce7eacc333ee373429d0451a86dd5d %}

- Now finally run following netlify commands to deploy the application and you need to select few option where you could either link this deployment to an existing site or to a new site. 
If you are doing it for the first time then select a new site and give it a new name.

```js
netlify deploy --prod
```

Finally you could check the deployment links and don't forget to append `/.netlify/functions/api` at the end of the deployment url to be able to access the node application.

What is serverless (and FaaS)
Tags: kubernetes, knative, serverless
Published: 2023-02-20 12:20:27

##### The need for Serverless computing
Serverless is a cloud computing model that can help you:
- Save money by paying only for what you use and avoiding idle resources.
- Save time by focusing on writing code and not managing servers or infrastructure.
- Scale easily by letting the provider handle the demand and availability of your applications.
- Innovate faster by leveraging existing services and platforms that offer various functionalities.

Image credit: [https://www.datavizz.in/what-is-serverless-computing/](https://www.datavizz.in/what-is-serverless-computing/)


##### FaaS
Functions as a Service (FaaS) is a type of serverless service that lets you execute self-contained code on-demand in response to events. With FaaS, the provider will spin up a server when a function is triggered, execute the function, then shut down the server. FaaS offerings are only active when the function is being used, allowing the same computing resources to be allocated elsewhere when the server is shut down.

##### Serverless v/s FaaS
Serverless is a broader cloud computing model that encompasses any service category where configuration, management, and billing of servers are invisible to the end user. Serverless services can include compute, storage, database, messaging, API gateways, etc. Serverless services can also leverage FaaS platforms for custom logic or backend functionality.

Some of the main differences between FaaS and serverless are:
1. FaaS is focused on executing code while serverless covers a wider range of services.
2. FaaS requires you to write stateless functions while serverless can support stateful applications through other services such as databases or caches.
3. FaaS has limitations on execution time and memory usage while serverless can offer more flexibility depending on the service type.
4. FaaS charges you based on function invocations and duration while serverless charges you based on different metrics such as storage capacity or API requests depending on the service type.

##### When to use them
FaaS and serverless can be useful for different scenarios depending on your needs and preferences. For example, you might use FaaS if you want to:
1. Run short-lived functions that perform simple tasks such as data processing, image resizing, or notifications.
2. Use multiple languages and frameworks for your functions.
3. Have more control over your function code and dependencies.

You might use serverless if you want to:
- Build stateful applications that require persistent storage or caching34.
- Use a wider range of services such as databases, messaging, API gateways, etc.
- Have more flexibility over your execution time and memory usage

Combining Postgresql with Apache AGE
Tags: postgres, apacheage
Published: 2023-02-20 12:09:34

**What is PostgreSql?**

PostgreSQL is an open-source relational database management system (RDBMS) that is designed to handle complex workloads, provide reliability, and support scalability. SQL (Structured Query Language), the most popular language for handling relational databases, is supported by PostgreSQL. Object-oriented programming support, JSON and XML data types, among other capabilities not present in other RDBMS systems, are also included. The dependability and capacity for high-volume transactional workloads of PostgreSQL are well known. Moreover, it offers strong management capabilities for data security and integrity, including row-level locking, multi-version concurrency control (MVCC), and transaction processing.



**What is Apache AGE?**

Apache AGE is an extension to the Apache Spark ecosystem that allows users to run graph queries directly on data stored in a PostgreSQL database. It is an open-source project developed by the Apache Software Foundation and is currently in the incubation stage.
         Without requiring data to be transferred from PostgreSQL and into a different graph database, Apache AGE offers a mechanism to execute complicated graph queries. The complexity and expense of administering many data storage may be lessened as a result.



**PostgreSql with Apache Age**

Apache AGE builds on top of PostgreSQL, adding support for graph data structures and query language. AGE introduces new data types, including vertex and edge, which enable users to store and manipulate graph data efficiently. AGE also provides a Cypher-like query language that allows users to query graph data using graph pattern matching.

It's simple to combine Apache AGE and PostgreSQL. Users can add additional data types and query operations to PostgreSQL by installing AGE as a PostgreSQL extension. Users can build and manage graph data using common PostgreSQL SQL statements, such INSERT, UPDATE, and DELETE, after installing the software.


**Conclusion**

In conclusion, combining PostgreSQL with Apache AGE offers users a powerful and flexible solution for managing graph data. Apache AGE basically enhances PostgreSQL's relational database capabilities by incorporating graph database features. Data can be stored, accessed, and analyzed as a graph using Apache AGE, which is especially helpful for large, interconnected data sets. Using AGE, users may model and query relationships between data by using graph database features including nodes, edges, and properties.

Also, AGE integrates with PostgreSQL's SQL engine, which means that users can leverage their existing knowledge of SQL to query and analyze graph data.
Postgres indexing Types - A Brief Description
Tags: postgres, apacheage, opensource
Published: 2023-02-20 12:08:41

PostgreSQL is a popular open-source relational database management system that provides a variety of advanced features to support efficient and effective data management. One of the most important features of PostgreSQL is indexing, which allows developers to improve the speed and efficiency of data retrieval. PostgreSQL supports several types of indexes, including B-tree, Hash, GiST,  GIN, and BRIN. In this article, we will discuss each of these index types briefly.


 
## B-tree Indexes :
 

The B-tree index is the default index in PostgreSQL. It is a balanced tree structure that stores the values of a column in sorted order, allowing for fast searches using comparison operators such as equal, greater than, or less than. B-tree indexes are ideal for queries that involve range queries and pattern matching.

## Hash Indexes :

Hash indexes are used to perform fast equality queries on a single column. They are best suited for queries that involve simple equality checks, such as looking up a specific value in a column. 

## GiST Indexes :

The Generalized Search Tree (GiST) index is a generic index type that can support complex data types such as geometric data, full-text search, and array data. GiST indexes provide efficient search capabilities for data types that do not support comparison operators.

GiST indexes are built using an extensible framework that allows the development of custom operators and search algorithms for specific data types.

## GIN Indexes :

The Generalized Inverted Index (GIN) is a specialized index type that is designed to support full-text search and array data. GIN indexes provide faster search capabilities for complex data types compared to GiST indexes.

GIN indexes are built by creating an inverted index that maps each value in a column to a list of row locations where that value occurs. This allows for efficient searches of the inverted index to find the rows that match a particular query.

## BRIN Indexes :

The Block Range INdex (BRIN) is a specialized index type that is used to optimize the retrieval of large tables by dividing them into ranges based on a sorted column. This index type is best suited for tables with a large number of rows.
