JavaScript/Typescript library for making AWS Lambda to Lambda calls via openapi-client-axios .\n\n## Versioning\n\n### 0.x to 1.x\n- changed to AWS SDK v3 to reduce bundle size and allow the update to the Node 18 runtime\n\n## Features\n\n- [x] Easy to make API like calls via openapi-client-axios library.\n```javascript\n client.api.registerRunner(getLambdaRunner('target-lambda-name'))\n```\n- [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.\n - `client.getPet(1)`\n - `client.searchPets()`\n - `client.searchPets({ ids: [1, 2, 3] })`\n - `client.updatePet(1, payload)`\n- [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.\n- [x] Leverage AWS IAM for permission management.\nEg:\n```yaml\n Resources:\n MyLambda:\n Type: AWS::Serverless::Function\n Properties:\n ...\n Policies:\n - LambdaInvokePolicy:\n FunctionName: target-lambda-name\n```\n\n## Restrictions\n- [x] To run in AWS Lambda with Nodejs Runtime Environment >= 12\n\n## Quick Start\n\n```\nnpm install --save openapi-client-axios openapi-lambda-adapter\n```\n\n\nSetup for single lambda handling all API Gateway requests \n\n```javascript\nimport OpenAPIClientAxios from 'openapi-client-axios';\nimport { getLambdaRunner } from 'openapi-lambda-adapter';\n\nconst api = new OpenAPIClientAxios({ definition: 'https://example.com/api/openapi.json' });\nconst client = api.initSync();\nclient.api.registerRunner(getLambdaRunner('target-lambda-name'));\n\nconst res = await client.createPet(null, { name: 'Garfield' });\nconsole.log('Pet created', res.data);\n```\n\nSetup for multiple lambdas, each lambda handling one API Gateway resource \n\n```javascript\nimport OpenAPIClientAxios from 'openapi-client-axios';\nimport { getLambdaRunner } from 'openapi-lambda-adapter';\n\nconst api = new OpenAPIClientAxios({ definition: 'https://example.com/api/openapi.json' });\nconst client = api.initSync();\nclient.api.getOperations().forEach((operation) => {\n const lambdaName = ... get lambda-name for operationId\n client.api.registerRunner(getLambdaRunner(lambdaName), operation.operationId)\n })\n\nconst res = await client.createPet(null, { name: 'Garfield' });\nconsole.log('Pet created', res.data);\n\nconst resp = await client.getPet({ id: 1 }, null);\nconsole.log('Pet retrieved', resp.data);\n```","readmeFilename":"README.md"}
