lambdeploy

A package for creating AWS lambda functions which build and deploy statically-generated websites.

npm install lambdeploy --save

Example index.js

var lambdeploy = require('lambdeploy');
var fs = require('fs');
var path = require('path');
exports.handler = lambdeploy.createHandler(function(workingDir, callback) {
    var buildDir = path.join(workingDir, 'build');
    fs.writeFile(path.join(buildDir, 'index.html'), 'Hello world\n', function(err) {
        callback(err, buildDir);
    });
});

lambdeploy.createHandler takes a "build function" and returns a handler function which is exported and used to make an AWS lambda.

The "build function" will be called with a working directory and a callback. At runtime that working directory will contain the source files to be built. The build function must attempt to build them and then call the callback with the either an error, or the path of the directory containing the output of the build. That output directory is what the lambda will deploy to an S3 bucket.

In the simple example above, the build function simply outputs "Hello world" to build/index.html.

Local testing

npm install -g lambda-local
lambda-local -l test.js -e test-event.json -t 60
