AWS Lambda Appsync Cognito S3 Route53 Infrastructure Setup For Backend API

GraphQL API with AWS AppSync and MongoDB Template

An example serverless app created with SST.

Getting Started

Read the tutorial

Install the example.

git clone https://github.com/SonuKumar81800/AWS_Backend.git

cd AWS_Backend

npm install || yarn install

Install and Configure AWS cli

• Download AWS Cli too from AWS Official
• Install it in your local system.
• Once your local environment is ready, head over to the AppSync console and get your access key id and secret here.

Open Terminal and follow these steps.

aws configure

AWS Access Key ID: <your_access_key_id>

AWS Secret Access Key:  <your_access_key_secret>

Default region name:  <select_your_region>

Default output format: json

Start the Live Lambda Development environment.

$ npm sst start

These Key Value you need to add to .env file

MONGO_USERNAME=<env_value>
MONGO_PASSWORD=<env_value>
DATABASE_NAME=<env_value>
DATABASE=<env_value>
GRAPHQL_API_URL=<env_value>
GRAPHQL_API_KEY=<env_value>

Commands

npm run start

Starts the local Lambda development environment.

npm run build

Build your app and synthesize your stacks.

Generates a .build/ directory with the compiled files and a .build/cdk.out/ directory with the synthesized CloudFormation stacks.

npm run deploy [stack]

Deploy all your stacks to AWS. Or optionally deploy a specific stack.

aws_backend's Issues

Getting Error while adding string[] type to schema

Getting this error becouse of multiple graphql source in Stack Configuration.

Is there any way i can use seperate graphql schema for each section so that it will be easy to manage large applicatios.
