![]() If the offline plugin has run the Serverless successfully, you’ll get a list of API GW endpoints similar to the below: GET | POST | Now, if the Lambda invoked requires access to DynamoDB, you’ll receive an error, this is because we need to create our local db instance and point our calling code to the local address of this emulation, let’s do that now. Next, you’ll want to locate the plugins section (this is present in most Serverless templates) and add those plugins, it should look like this in TypeScript: service: "serverless-offline-with-dynamodb",Īwesome, now we’ll run our Serverless offline plugin, we’ll pass in a stage environment since some of our IaC expects a stage variable such as our table. It’s also worth mentioning that DynamoDB local will require JRE which can be found here Getting Startedįirst, you’ll want to install those plugins as dev dependencies, so: npm i -save-dev serverless-offline serverless-dynamodb-local Serverless DynamoDB Local - This will create an emulation of DynamoDB locally which is required for the Lambdas in this scenario. ![]() Serverless Offline - Used to locally run Lambdas and API Gateway, will provide an endpoint per Lambda and supports hot reloading during development. ![]() Pluginsįor this we’re going to install several Serverless plugins, these provide additional functionality and cater for many common scenarios that may arise during development or simply enhancing IaC. You have different environments (beta/staging/production) and would like an env for local development to easily use specific configs.Īn example of this all working can be found here □. You want the ability to test your code locally whilst developing functionality and easily give other developers the same ability just by cloning and running the project. You have written some Serverless IaC and have created several Lambdas which need to either read or write to DynamoDB, the Lambdas are proxied through an API gateway. The default tsconfig.Setup not related to this article will be skipped for brevity. ![]() See example folder for a minimal example. Npm install -D serverless-plugin-typescript typescriptĪdd the following plugin to your serverless.yml: plugins: - serverless-plugin-typescript Configure Install yarn add -dev serverless-plugin-typescript typescript Integrates nicely with serverless-offline.Supports sls invoke local + -watch mode.Supports sls package, sls deploy and sls deploy function.Supports ES2015 syntax + features ( export, import, async, await, Promise.Zero-config: Works out of the box without the need to install any other compiler or plugins. ![]() Serverless plugin for zero-config Typescript support Features ![]()
