-### Reading Data
+### Overview
-In the Lambda handler, the `event.body` attribute is a Base64-encoded string
-representing the HTTP request form data. This body must be parsed.
+Cloudflare Workers exposes a handler in src/index.(js|ts) when you create a worker project using C3 as per above,
+this handler exposes a Request object which can be used to expose the formdata or json of the request to the worker
-#### Processing Form Bodies
-
-The `busboy` body parser[^2] is battle-tested in NodeJS deployments.
-
-`busboy` fires a `'file'` event for every file in the form body. The callback
-receives a NodeJS stream that should be collected into a Buffer:
-
-```js
-/* accumulate the files manually */
-var files = {};
-bb.on('file', function(fieldname, file, filename) {
- /* concatenate the individual data buffers */
- var buffers = [];
- file.on('data', function(data) { buffers.push(data); });
- file.on('end', function() { files[fieldname] = Buffer.concat(buffers); });
-});
-```
-
-`busboy` fires a `'finish'` event when the body parsing is finished. Callbacks
-can assume every file in the form body has been stored in NodeJS Buffer objects.
-
-#### Processing NodeJS Buffers
-
-The SheetJS `read` method[^3] can read the Buffer objects and generate SheetJS
-workbook objects[^4] which can be processed with other API functions.
-
-For example, a handler can use `sheet_to_csv`[^5] to generate CSV text:
-
-```js
-/* on the finish event, all of the fields and files are ready */
-bb.on('finish', function() {
- /* grab the first file */
- var f = files["upload"];
- if(!f) callback(new Error("Must submit a file for processing!"));
-
- /* f[0] is a buffer */
- // highlight-next-line
- var wb = XLSX.read(f[0]);
-
- /* grab first worksheet and convert to CSV */
- var ws = wb.Sheets[wb.SheetNames[0]];
- callback(null, { statusCode: 200, body: XLSX.utils.sheet_to_csv(ws) });
-});
-```

-
-This example takes the first uploaded file submitted with the key `upload`,
-parses the file and returns the CSV content of the first worksheet.
-
-```js
-const XLSX = require('xlsx');
-var Busboy = require('busboy');
-
-exports.handler = function(event, context, callback) {
- /* set up busboy */
- var ctype = event.headers['Content-Type']||event.headers['content-type'];
- var bb = Busboy({headers:{'content-type':ctype}});
-
- /* busboy is evented; accumulate the fields and files manually */
- var fields = {}, files = {};
- bb.on('error', function(err) { callback(null, { body: err.message }); });
- bb.on('field', function(fieldname, val) {fields[fieldname] = val });
- // highlight-start
- bb.on('file', function(fieldname, file, filename) {
- /* concatenate the individual data buffers */
- var buffers = [];
- file.on('data', function(data) { buffers.push(data); });
- file.on('end', function() { files[fieldname] = [Buffer.concat(buffers), filename]; });
- });
- // highlight-end
-
- /* on the finish event, all of the fields and files are ready */
- bb.on('finish', function() {
- /* grab the first file */
- var f = files["upload"];
- if(!f) callback(new Error("Must submit a file for processing!"));
-
- /* f[0] is a buffer */
- // highlight-next-line
- var wb = XLSX.read(f[0]);
-
- /* grab first worksheet and convert to CSV */
- var ws = wb.Sheets[wb.SheetNames[0]];
- callback(null, { statusCode: 200, body: XLSX.utils.sheet_to_csv(ws) });
- });
-
- /* start the processing */
- // highlight-next-line
- bb.end(Buffer.from(event.body, "base64"));
+```ts
+export default {
+ async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise {
+ const data = await request.formData()
+ // const data = await request.json() if you are receiving a json request
+ //...

-
-This example creates a sample workbook object and sends the file in the response:
-
-```js
-var XLSX = require('xlsx');
-
-exports.handler = function(event, context, callback) {
- /* make workbook */
- var wb = XLSX.read("S,h,e,e,t,J,S\n5,4,3,3,7,9,5", {type: "binary"});
- /* write to XLSX file in Base64 encoding */
- // highlight-next-line
- var body = XLSX.write(wb, { type: "base64", bookType: "xlsx" });
- /* mark as attached file */
- var headers = { "Content-Disposition": 'attachment; filename="SheetJSLambda.xlsx"'};
- /* Send back data */
- callback(null, {
- statusCode: 200,
- // highlight-next-line
- isBase64Encoded: true,
- body: body,
- headers: headers
- });
+```ts
