Installing node-canvas for Lambda using docker-lambda

Assumes your Lambda handler (eg index.js, app.js, etc) is in the current directory and you've already run npm install locally (ie, you have ./node_modules already) – the OS you ran it on shouldn't matter.

nodejs8.10 and nodejs10.x

This will reinstall any native module binaries, with our current directory mounted as /var/task, which mirrors where it mounts in Lambda

// Get the key from the "DSN" at: https://sentry.io/settings/<org>/projects/<project>/keys/
// The "DSN" will be in the form: https://<SENTRY_KEY>@sentry.io/<SENTRY_PROJECT_ID>
// eg, https://0000aaaa1111bbbb2222cccc3333dddd@sentry.io/123456
const SENTRY_PROJECT_ID = '123456'
const SENTRY_KEY = '0000aaaa1111bbbb2222cccc3333dddd'

// Useful if you have multiple apps within a project – not necessary, only used in TAGS and SERVER_NAME below
const APP = 'my-app'
