Installation

You need Go 1.13+ to compile the binary. If you have an older version of Go and don't want to install the tarball manually, you can install newer version of Go into your GOPATH:

0. Install Go 1.14

   $ go get golang.org/dl/go1.14.2
   # Assuming your GOPATH is default (~/go), Go 1.14.2 will be installed in ~/go/bin
   $ ~/go/bin/go1.14.2 version
   go version go1.14.2 linux/amd64
   

1. Clone this repository:

   git clone github.com/librespeed/speedtest-go
   

2. Build

   # Change current working directory to the repository
   $ cd speedtest-go
   # Compile
   $ go build -ldflags "-w -s" -trimpath -o speedtest main.go
   

3. Copy the assets directory, settings.toml file along with the compiled speedtest binary into a single directory

4. If you have telemetry enabled,

   • For PostgreSQL/MySQL, create database and import the corresponding .sql file under database/{postgresql,mysql}

     # assume you have already created a database named `speedtest` under current user
     $ psql speedtest < database/postgresql/telemetry_postgresql.sql
     

   • For embedded BoltDB, make sure to define the database_file path in settings.toml:

     database_file="speedtest.db"
     

5. Put assets folder under the same directory as your compiled binary.

   • Make sure the font files and JavaScripts are in the assets directory
   • You can have multiple HTML pages under assets directory. They can be access directly under the server root (e.g. /example-singleServer-full.html)
   • It's possible to have a default page mapped to /, simply put a file named index.html under assets

6. Change settings.toml according to your environment:

   # bind address, use empty string to bind to all interfaces
   bind_address="127.0.0.1"
   # backend listen port, default is 8989
   listen_port=8989
   # proxy protocol port, use 0 to disable
   proxyprotocol_port=0
   # Server location, use zeroes to fetch from API automatically
   server_lat=0
   server_lng=0
   # ipinfo.io API key, if applicable
   ipinfo_api_key=""
   
   # assets directory path, defaults to `assets` in the same directory
   assets_path="./assets"

Differences between Go and PHP implementation and caveats

• Since there is no CGo-free SQLite implementation available, I've opted to use BoltDB instead, as an embedded database alternative to SQLite
• Test IDs are generated ULID, there is no option to change them to plain ID
• You can use the same HTML template from the PHP implementation
• Server location can be defined in settings
• There might be a slight delay on program start if your Internet connection is slow. That's because the program will attempt to fetch your current network's ISP info for distance calculation between your network and the speed test client's. This action will only be taken once, and cached for later use.
