It is no brainer that the e-commerce market has transformed the Indian market like never before. Thanks to factors like rising smartphone penetration, the launch of 4G network, and increasing consumer wealth, analytics-driven customer engagement, and digital payment, the e-commerce sector is on an upward trajectory. It is projected that this industry will surpass the US to become the second-largest E-commerce market in the world by 2034. According to the PWC survey, with Internet penetration expected to almost double to 60% by 2022, the nation is arguably the world’s most promising Internet economy, with a rapidly increasing ‘netizen’ population. Further owing to improving data affordability, consumption growth, and newer financial products, the e-commerce market is set to grow, be it across e-tail, travel, consumer services or online financial services. This also implies e-commerce will not only boost the Indian economy but it will also have a cascading effect on other industrial verticals too. Meanwhile, the niche leaders are now planning to invest in machine learning to enhance the offerings of this sector.
Machine learning is known for its ability to self-learn and retrain itself by studying a given data set. In the e-commerce space, this AI application can learn what customers prefer and how they want to see information to get them to make a purchase. Then it can test and adapt, using new options and information to slowly refine the best way to reach your customers.
When a user wants a product on an e-commerce store, he needs to search for it using the preferred keywords. So, the site owner must ensure that they have attributed those keywords to products that users are searching for. Machine learning looks for synonyms in the nouns provided by a user as well as similar phrases people use for the same type of problem. It does this by analyzing the site and its metrics, thus, allowing e-commerce sites to prioritize click rates and existing conversions while putting high-rated products on the top of the page.

This serverless plugin is a wrapper for amplify-appsync-simulator made for testing AppSync APIs built with serverless-appsync-plugin.
Install
npm install serverless-appsync-simulator
# or
yarn add serverless-appsync-simulator
Usage
This plugin relies on your serverless yml file and on the serverless-offline
plugin.
plugins:
- serverless-dynamodb-local # only if you need dynamodb resolvers and you don't have an external dynamodb
- serverless-appsync-simulator
- serverless-offline
Note: Order is important serverless-appsync-simulator
must go before serverless-offline
To start the simulator, run the following command:
sls offline start
You should see in the logs something like:
...
Serverless: AppSync endpoint: http://localhost:20002/graphql
Serverless: GraphiQl: http://localhost:20002
...
Configuration
Put options under custom.appsync-simulator
in your serverless.yml
file
| option | default | description | | ------------------------ | -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | | apiKey | 0123456789
| When using API_KEY

(base directory) | Location of the lambda functions handlers. | | refMap | {} | A mapping of resource resolutions for the Ref

function | | importValueMap | {} | A mapping of resource resolutions for the ImportValue
function | | functions | {} | A mapping of external functions for providing invoke url for external fucntions | | dynamoDb.endpoint | http://localhost:8000 | Dynamodb endpoint.

Possible values (mysql | postgres) | | rds.dbUsername | | Database username | | rds.dbPassword | | Database password | | rds.dbPort | | Database port | | watch | - *.graphql
- *.vtl | Array of glob patterns to watch for hot-reloading. |
Example:
custom:
appsync-simulator:
location: '.webpack/service' # use webpack build directory
dynamoDb:
endpoint: 'http://my-custom-dynamo:8000'
Hot-reloading
By default, the simulator will hot-relad when changes to *.graphql
or *.vtl
files are detected. Changes to *.yml
files are not supported (yet? - this is a Serverless Framework limitation). You will need to restart the simulator each time you change yml files.
Hot-reloading relies on watchman. Make sure it is installed on your system.
You can change the files being watched with the watch
option, which is then passed to watchman as the match expression.
e.g.
custom:
appsync-simulator:
watch:
- ["match", "handlers/**/*.vtl", "wholename"] # => array is interpreted as the literal match expression
- "*.graphql" # => string like this is equivalent to `["match", "*.graphql"]`
Or you can opt-out by leaving an empty array or set the option to false
Note: Functions should not require hot-reloading, unless you are using a transpiler or a bundler (such as webpack, babel or typescript), un which case you should delegate hot-reloading to that instead.
Resource CloudFormation functions resolution
This plugin supports some resources resolution from the Ref
, Fn::GetAtt
and Fn::ImportValue
functions in your yaml file. It also supports some other Cfn functions such as Fn::Join
, Fb::Sub
, etc.
Note: Under the hood, this features relies on the cfn-resolver-lib package. For more info on supported cfn functions, refer to the documentation
You can reference resources in your functions' environment variables (that will be accessible from your lambda functions) or datasource definitions. The plugin will automatically resolve them for you.
provider:
environment:
BUCKET_NAME:
Ref: MyBucket # resolves to `my-bucket-name`
resources:
Resources:
MyDbTable:
Type: AWS::DynamoDB::Table
Properties:
TableName: myTable
...
MyBucket:
Type: AWS::S3::Bucket
Properties:
BucketName: my-bucket-name
...
# in your appsync config
dataSources:
- type: AMAZON_DYNAMODB
name: dynamosource
config:
tableName:
Ref: MyDbTable # resolves to `myTable`
Sometimes, some references cannot be resolved, as they come from an Output from Cloudformation; or you might want to use mocked values in your local environment.
In those cases, you can define (or override) those values using the refMap
, getAttMap
and importValueMap
options.
refMap
takes a mapping of resource name to value pairsgetAttMap
takes a mapping of resource name to attribute/values pairsimportValueMap
takes a mapping of import name to values pairsExample:
custom:
appsync-simulator:
refMap:
# Override `MyDbTable` resolution from the previous example.
MyDbTable: 'mock-myTable'
getAttMap:
# define ElasticSearchInstance DomainName
ElasticSearchInstance:
DomainEndpoint: 'localhost:9200'
importValueMap:
other-service-api-url: 'https://other.api.url.com/graphql'
# in your appsync config
dataSources:
- type: AMAZON_ELASTICSEARCH
name: elasticsource
config:
# endpoint resolves as 'http://localhost:9200'
endpoint:
Fn::Join:
- ''
- - https://
- Fn::GetAtt:
- ElasticSearchInstance
- DomainEndpoint
In some special cases you will need to use key-value mock nottation. Good example can be case when you need to include serverless stage value (${self:provider.stage}
) in the import name.
This notation can be used with all mocks - refMap
, getAttMap
and importValueMap
provider:
environment:
FINISH_ACTIVITY_FUNCTION_ARN:
Fn::ImportValue: other-service-api-${self:provider.stage}-url
custom:
serverless-appsync-simulator:
importValueMap:
- key: other-service-api-${self:provider.stage}-url
value: 'https://other.api.url.com/graphql'
This plugin only tries to resolve the following parts of the yml tree:
provider.environment
functions[*].environment
custom.appSync
If you have the need of resolving others, feel free to open an issue and explain your use case.
For now, the supported resources to be automatically resovled by Ref:
are:
Feel free to open a PR or an issue to extend them as well.
External functions
When a function is not defined withing the current serverless file you can still call it by providing an invoke url which should point to a REST method. Make sure you specify "get" or "post" for the method. Default is "get", but you probably want "post".
custom:
appsync-simulator:
functions:
addUser:
url: http://localhost:3016/2015-03-31/functions/addUser/invocations
method: post
addPost:
url: https://jsonplaceholder.typicode.com/posts
method: post
Supported Resolver types
This plugin supports resolvers implemented by amplify-appsync-simulator
, as well as custom resolvers.
