Pambda for JSON API.

Installation

Usage

const { compose, createLambda } = require('pambda');
const { router } = require('pambda-router');
const { jsonApi } = require('pambda-json-api');
 
export const handler = createLambda(
  compose(
    router()
      .post('/api/(.*)', compose(
         jsonApi({
           reqJsonOnly: true,
           resJsonOnly: true,
           errorHandler: (err, event, context, callback) => {
             // Custom error handling
           },
         }),
         next => (event, context, callback) => {
           // API handling
         },
      ))
      .toPambda()
  )
);

jsonApi(options)

• options.reqJsonOnly
  • The boolean value on whether to accept a JSON request only. If true, an error occurs for requests that Content-Type is not application/json.
  • The default value is true.
• options.resJsonOnly
  • The boolean value to whether to return a JSON response only. If true, call JSON.stringify() and set Content-Type.
  • The default value is true.
• options.errorHandler
  • The function with argument (err, event, context, callback), called when an error occurs.
  • The default is to return Internal Server Error.

When receiving a JSON request, set the result of parsing JSON to event.body. Subsequent Pambda can use parsed body.

Also, if necessary, return body as a JSON string for the result that subsequent Pambda passes to callback.
