ndt7-js

The official NDT7 Javascript client library. This code works in all modern browsers and is the source for the npm package @m-lab/ndt7.

Includes an example web client in the examples/ directory. Pull requests gratefully accepted if you would like to write a more sophisticated web client that uses the returned measurements to debug network conditions.

In case you need a standalone client binary that you can build and run on multiple operating systems and CPU architectures (including embedded devices) have a look at the official Go client instead.

ndt7.discoverServerURLS

discoverServerURLs contacts a web service (likely the Measurement Lab locate service, but not necessarily) and gets URLs with access tokens in them for the client. It can be short-circuted if config.server exists, which is useful for clients served from the webserver of an NDT server.
