music-token-cli

cli written in go (with cobra) that consumes information about albums, songs and artists from spotify API endpoints using the provided JWT

How to create a cli in go with cobra

Create the go project

go mod init my project

Install cobra

go get -u github.com/spf13/cobra/cobra

Create the cobra boilerplate

cobra init --pkg-name my project

Add commands to the cli

cobra add my-new-command

Adding subcommands

To add a subcommand execute the same cobra command to add a new command. Then go to the file you want to be the primary command of this new command. Edit the init method with the primary command.

func init() {
   artistCmd.AddCommand(bynameCmd)
}

The easy way:

cobra add name -p "artistCmd"

Adding flags

Global flags are in root.go

Local flags go in the respective command

Running the cli

To build a particular command use

go run . my-project subcommand1 subcommand2

Build the project & running as binary

go build -o my-project

./my-project

Troubleshooting

cobra: command not found

vi ~/.zshrc

export GOPATH=$HOME/go
export GOBIN=$GOPATH/bin
export PATH=${PATH}:$GOBIN

source ~/.zshrc

NOTE: Always use camel case rather than snake case because that may lead to errors
