Basic Usage

Use this component to quickly add a discussion or a chat / group feature into your application. After you become familiar with the basic usage, you can move on to exploring the props, further features and customization.


import React from 'react'

import { Col, Row, Container } from 'react-bootstrap';
import { DiscussionView } from 'react-discussionview'
import Themes from 'react-ui-themes-superflows'
import 'bootstrap/dist/css/bootstrap.min.css';

const App = () => {

  const theme = Themes.getTheme("Default");

  return (
    <Container className='mt-5'>
      <Row className='justify-content-center'>
        <Col sm={12} xs={12} md={8} xl={6} xxl={6} >
          <DiscussionView
            awsRegion="your_aws_region_where_s3_bucket_and_table_is_hosted"
            awsKey="your_aws_access_key"
            awsSecret="your_aws_secret"
            awsMediaConvertEndPoint="your_aws_mediaconvert_endpoint"
            mediaConvertRole="your_aws_mediaconvert_role"
            topicId="4"
            table="your_dynamodb_table_name"
            bucket="your_aws_s3_bucket_name"
            userId="23"
            userName="Kaushiki M"
            userPicture="https://superflows-myuploads.s3.ap-south-1.amazonaws.com/profile_girl_100.png"
            theme={theme}
          />
        </Col>
      </Row>
    </Container>
  )
}

export default App

Immediately after initialization, your discussion will not have any data. So you will only see the editor.


Type in something and submit it.


Whatever you have entered and submitted, will be reflected as a chat box just above the editor. Type in something more!


Your second chat is also now visible. What if you wish to add a new user to chat? It's quite simple actually, just change the user-related props! See the below example.

import React from 'react'

import { Col, Row, Container } from 'react-bootstrap';
import { DiscussionView } from 'react-discussionview'
import Themes from 'react-ui-themes-superflows'
import 'bootstrap/dist/css/bootstrap.min.css';

const App = () => {

  const theme = Themes.getTheme("Default");

  return (
    <Container className='mt-5'>
      <Row className='justify-content-center'>
        <Col sm={12} xs={12} md={8} xl={6} xxl={6} >
          <DiscussionView
            awsRegion="your_aws_region_where_s3_bucket_and_table_is_hosted"
            awsKey="your_aws_access_key"
            awsSecret="your_aws_secret"
            awsMediaConvertEndPoint="your_aws_mediaconvert_endpoint"
            mediaConvertRole="your_aws_mediaconvert_role"
            topicId="4"
            table="your_dynamodb_table_name"
            bucket="your_aws_s3_bucket_name"
            userId="21"
            userName="Hrushi M"
            userPicture="https://superflows-myuploads.s3.ap-south-1.amazonaws.com/profile_boy_100.jpeg"
            theme={theme}
          />
        </Col>
      </Row>
    </Container>
  )
}

export default App


You'll see that the chat has remained the same but the user at the bottom editor has changed. This essentially means that you are now using the chat as a different user. This is achieved by changing the user-related props - userId, userName, userPicture.


Go ahead, type in something with the new user!


You'll see that your chat input from the new user is now showing in the chatroom!


The quickstart section ends here. You can now move on to the props section, to understand the props in detail.

        </Col>
      </Row>
    </Container>
  )
}

export default App


AWS Configuration

AWS S3

  • Create an S3 bucket via the AWS admin console, say name of the bucket is myuploads
  • Set the bucket policy as follows
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "PublicListGet",
            "Effect": "Allow",
            "Principal": "*",
            "Action": [
                "s3:List*",
                "s3:Get*"
            ],
            "Resource": [
                "arn:aws:s3:::myuploads",
                "arn:aws:s3:::myuploads/*"
            ]
        }
    ]
}
  • Set the cors policy as follows
[
    {
        "AllowedHeaders": [
            "*"
        ],
        "AllowedMethods": [
            "PUT",
            "POST",
            "DELETE",
            "GET"
        ],
        "AllowedOrigins": [
            "*"
        ],
        "ExposeHeaders": []
    }
]

AWS IAM

SDK User

  • Create an SDK user via the AWS console so that you get access to aws region, aws access key and aws secret, i.e. aws credentials.
  • Ensure that you preserve these credentials in a secure manner.
  • It is especially important that these credentials be stored in the environment files and should never be pushed to a source repository such as git.
  • For this SDK user, give create, add, edit, delete permissions to your S3 bucket via the AWS console. I usually give full access restricted to a particular bucket, like the one which we created in the S3 section above
{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "s3:*",
                "s3-object-lambda:*"
            ],
            "Resource": "arn:aws:s3:::myuploads"
        }
    ]
}
  • For this SDK user, then give the user access to AWS mediaconvert via the AWS console. I have used AWSElementalMediaConvertFullAccess, which is a pre-created AWS policy for this. To find and attach this policy - Select your IAM user > Click add permissions on the user summary screen > Click attach existing policies directly > Search mediaconvert > Apply the AWSElementalMediaConvertFullAccess policy
  • For this SDK user, give create, add, edit, delete permissions to your DynamoDB table as well.

MediaConvert Role

  • Goto IAM > Roles
  • Select AWS Service as the trusted entity type
  • Choose MediaConvert from the services dropdown
  • Click next on add permissions
  • Name the role as per your choice. I have named it mediaconvert_role. (Remember that this role name has to be given as a prop to the upload-to-s3 component, refer to the Usage section)

AWS MediaConvert

AWS mediaconvert is required for video processing. The clip selection happens at the client end, whereas the actual clipping is done by an AWS mediaconvert job. This requires a region specific endpoint and can be easily obtained from the aws cli (aws commandline).

aws mediaconvert describe-endpoints --region <region>

Remember that this region specific endpoint also has to be provided as a prop to the upload-to-s3 component. (Refer to the Usage Section)

Once you are through with installing the dependencies and the AWS configuration, using the component becomes fairly simple. Please refer to the Usage below.

AWS DynamoDB

This component uses dynamodb as the backend. Please create a table as follows. You can use a name of your choice but remember to use the same name in the props.

Name: Discussions / "your_dynamodb_table_name" Partition Key: topicId (String) Sort Key: timestamp (number)

As mentioned above, don't forget to provide CRUD access to this table to your SDK user.
