Development

Bundling and types

This project is isomorphic, meaning it's a single library which contains both browser and server builds. It's written in TypeScript, and transpiled and bundled with Rollup. Our Rollup config generates three main files:

1. The server build, which transpiles src/server.ts and its dependencies into dist/server/honeybadger.js.
2. The browser build, which transpiles src/browser.ts and its dependencies into dist/browser/honeybadger.js.
3. The minified browser build, which transpiles src/browser.ts and its dependencies into dist/browser/honeybadger.min.js (+ source maps).

In addition, the TypeScript type declaration for each build is generated into its types/ directory (ie dist/browser/types/browser.d.ts and dist/server/types/server.d.ts).

However, since the package is isomorphic, TypeScript users will likely be writing import * as Honeybadger from '@honeybadger-io/js' or import Honeybadger = require('@honeybadger-io/js') in their IDE. Our package.json has main and browser fields that determine which build they get, but there can only be a single type declaration file. So we use an extra file in the project root, honeybadger.d.ts, that combines the types from both builds.

Tests

1. To run unit tests for both browser and server builds: npm test. Or separately: npm run test:browser, npm run test:server.
2. To run integration tests across all supported platforms, set up a BrowserStack account and use BROWSERSTACK_USERNAME=your_username BROWSERSTACK_ACCESS_KEY=your-access-key npm run test:integration.
3. To test the TypeScript type definitions: npm run tsd.

Releasing

This package comes with a postpublish script (scripts/release-cdn.sh) which is executed every time a new version is released to NPM. The script publishes to our js.honeybadger.io CDN (hosted on AWS via S3/CloudFront).

For the CDN release, make sure you have the following environment variable available in your shell:

export HONEYBADGER_JS_S3_BUCKET=honeybadger-js
export HONEYBADGER_DISTRIBUTION_ID=cloudfront-id

AWS credentials are read from ~/.aws/credentials, using the default profile.

If the CDN release fails for some reason (bad AWS credentials, for instance), re-run the release manually with by executing the script npm run postpublish.
