FAQ

I'm getting a TypeError: bufferUtil.mask is not a function

Under the hood, this library is using ws package and also bufferutil to enhance ws' performances.

Since bufferutil is a binary addon, it may or may not be installed correctly on your current platform due to potential incompatibilities.

In such cases, using the environment variable WS_NO_BUFFER_UTIL=1 will be necessary to resolve the issue.
