README

AnyCable-Go WebSocket Server

WebSocket server for AnyCable.

Important This is a readme for the upcoming v1.0 release. For v0.6.x see the readme from the 0-6-stable branch.

Versioning

Important Use the same major version of AnyCable-Go as your AnyCable gem. AnyCable-Go uses the same major version number (and minor version as well for 0.x series) as other libraries to indicate the compatibility.

NOTE: AnyCable-Go v1.0 is backward-compatible with v0.6.x series (to allow incremental upgrades). The next minor relase (v1.1) will drop 0.6.x support.

Installation

The easiest way to install AnyCable-Go is to download a pre-compiled binary.

MacOS users could install it with Homebrew

brew install anycable-go

Arch Linux users can install anycable-go package from AUR.

Of course, you can install it from source too:

go get -u -f github.com/anycable/anycable-go/cmd/anycable-go

NOTE: right now it's not possible to build anycable-go with mruby support using the command above. To install anycable-go with mruby from source try:

go get -d -u -f github.com/anycable/anycable-go/cmd/anycable-go && (cd $GOPATH/src/github.com/anycable/anycable-go && make prepare-mruby install-with-mruby)

Upgrade

For instructions on how to upgrade to a newer version see upgrade notes.

Heroku

See heroku-anycable-go buildpack.

Usage

Run server:

$ anycable-go

=> INFO 2020-02-05T08:44:57.684Z context=main Starting AnyCable 1.0.0

You can also provide configuration parameters through the corresponding environment variables (i.e. ANYCABLE_RPC_HOST, ANYCABLE_REDIS_URL, etc).

For more information about available options run anycable-go -h.

📑 Documentation

Redis Sentinel

To enable redis sentinel support set --redis-sentinels to a comma separated list of sentinels (format: <host>:<port>,...) and set the --redis-url like that: redis://[:<redis_password>@]<redis_master_name>

Build

# first, prepare mruby (we embed it by default)
make prepare-mruby

# then build the Go binary (will be available in dist/anycable-go)
make

You can run tests with the following commands:

# Run Golang unit tests
make test

# run once
make prepare

# Run integrations tests
make test-conformance

We use golangci-lint to lint Go source code:

golangci-lint run
