JavaScript/Typescript library for making AWS Lambda to Lambda calls via openapi-client-axios . ## Versioning ### 0.x to 1.x - changed to AWS SDK v3 to reduce bundle size and allow the update to the Node 18 runtime ## Features - [x] Easy to make API like calls via openapi-client-axios library. ```javascript client.api.registerRunner(getLambdaRunner('target-lambda-name')) ``` - [x] Use your API clients from [OpenAPI v3 definitions](https://github.com/OAI/OpenAPI-Specification) to make AWS Lambda to Lambda calls between your platform microservices. - `client.getPet(1)` - `client.searchPets()` - `client.searchPets({ ids: [1, 2, 3] })` - `client.updatePet(1, payload)` - [x] No need to run your requests via Api Gateway, you can directly run microservice to microservice call, i.e. AWS Lambda to Lambda, by leveraging AWS backbone infrastructure. - [x] Leverage AWS IAM for permission management. Eg: ```yaml Resources: MyLambda: Type: AWS::Serverless::Function Properties: ... Policies: - LambdaInvokePolicy: FunctionName: target-lambda-name ``` ## Restrictions - [x] To run in AWS Lambda with Nodejs Runtime Environment >= 12 ## Quick Start ``` npm install --save openapi-client-axios openapi-lambda-adapter ``` Setup for single lambda handling all API Gateway requests ```javascript import OpenAPIClientAxios from 'openapi-client-axios'; import { getLambdaRunner } from 'openapi-lambda-adapter'; const api = new OpenAPIClientAxios({ definition: 'https://example.com/api/openapi.json' }); const client = api.initSync(); client.api.registerRunner(getLambdaRunner('target-lambda-name')); const res = await client.createPet(null, { name: 'Garfield' }); console.log('Pet created', res.data); ``` Setup for multiple lambdas, each lambda handling one API Gateway resource ```javascript import OpenAPIClientAxios from 'openapi-client-axios'; import { getLambdaRunner } from 'openapi-lambda-adapter'; const api = new OpenAPIClientAxios({ definition: 'https://example.com/api/openapi.json' }); const client = api.initSync(); client.api.getOperations().forEach((operation) => { const lambdaName = ... get lambda-name for operationId client.api.registerRunner(getLambdaRunner(lambdaName), operation.operationId) }) const res = await client.createPet(null, { name: 'Garfield' }); console.log('Pet created', res.data); const resp = await client.getPet({ id: 1 }, null); console.log('Pet retrieved', resp.data); ``` --- _Source: https://npm.io/package/openapi-lambda-adapter · Machine-readable twin of the npm.io package page.
