This project has been generated using the aws-nodejs-typescript
template from the Serverless framework.
For detailed instructions, please refer to the documentation.
Depending on your favorite package manager, follow the instructions below to deploy your project.
Requirements: NodeJS
lts/fermium (v.14.15.0)
. If you're using nvm, runnvm use
to ensure you're using the same Node version in local and in your lambda's runtime.
- Run
npm i
to install the project dependencies. - Run
npx sls deploy
to deploy this stack to AWS
- Run
yarn

This template contains a single lambda function triggered by an HTTP request made on the provisioned API Gateway REST API /hello
route with POST
method. The request body must be provided as application/json
. The body structure is tested by API Gateway against src/functions/hello/schema.ts
JSON-Schema definition: it must contain the name
property.
- requesting any other path than
/hello
with any other method thanPOST
will result in API Gateway returning a403
HTTP error code - sending a
POST
request to/hello
with a payload not containing a string property namedname
will result in API Gateway returning a400
HTTP error code - sending a
POST
request to/hello
with a payload containing a string property namedname
will result in API Gateway returning a200
HTTP status code with a message saluting the provided name and the detailed event processed by the lambda
⚠️ As is, this template, once deployed, opens a public endpoint within your AWS account resources. Anybody with the URL can actively execute the API Gateway endpoint and the corresponding lambda. You should protect this endpoint with the authentication method of your choice.
In order to test the hello function locally, run the following command:
npx sls invoke local -f hello --path src/functions/hello/mock.json
if you're using NPMyarn sls invoke local -f hello --path src/functions/hello/mock.json
if you're using Yarn
Check the sls invoke local command documentation for more information.
Copy and replace your url
- found in Serverless deploy
command output - and name
parameter in the following curl
command in your terminal or in Postman to test your newly deployed application.
curl --location --request POST 'https://myApiEndpoint/dev/hello' \
--header 'Content-Type: application/json' \
--data-raw '{
"name": "Frederic"
}'
The project code base is mainly located within the src
folder. This folder is divided in:
functions
- containing code base and configuration for your lambda functionslibs
- containing shared code base between your lambdas.

- json-schema-to-ts - uses JSON-Schema definitions used by API Gateway for HTTP request validation to statically generate TypeScript types in your lambda's handler code base
- middy - middleware engine for Node.Js lambda. This template uses http-json-body-parser to convert API Gateway
event.body
property, originally passed as a stringified JSON, to its corresponding parsed object - @serverless/typescript - provides up-to-date TypeScript definitions for your
serverless.ts
service file
Any tsconfig.json can be used, but if you do, set the environment variable TS_NODE_CONFIG
for building the application, eg TS_NODE_CONFIG=./tsconfig.app.json npx serverless webpack
