Hopper

Hop between databases with ease whilst developing locally on Laravel.

Imagine: A colleague asks you to check their PR out. But you're working on a new feature yourself and your local database is *just* right. You've got it tuned with the right models, the right data - losing it would just be an inconvenience too far...

So now imagine: A colleague asks you to check their PR out. You jump onto their branch, set up your database - migrate it, seed it, wipe it, whatever - and review their work. Then, you return to your feature and pick up where you left off - with your database still intact.

Enter Hopper. It's as simple as:

Now, you're on a database called awesome_new_feature.

With Git, it's even simpler:

Now, you're on a database for the current branch!

And you can always hop back to your default database with:

Now, you're on the default database as configured by your Laravel settings.

Installation

You can install the package via composer:

Setup

Hopper comes with a config file for you to publish to config/hopper.php:

You don't need to publish the config file to use Hopper, but it is recommended. But no pressure. Honest... See configuration to see whether you want to for your project.

Usage

Commands:

• hop
• hop:current
• hop:delete

Configuration:

• Default Git Branch
• Connections
  • Sqlite
  • MySql
  • Adding Your Own
• Boot Checks
• Post Creation Steps

Commands

hop

This is the core command when using Hopper. There are 3 ways it can be used:

• Use a database for the current Git branch
• Use a specific database
• Use the default database

Using a database for the current Git branch

This option is where Hopper really shines. Simply checkout a branch, hop, and you're on a new database. Checkout your previous branch, hop, and you're back to where you started.

To use Hopper this way, simply hop without arguments:

Now, when using your app, it will be connected to the updates database.

Your default Git branch aliases to your default database. So, imagine main is your default branch. When you run this:

You won't move to the a database called main. Instead, you'll be moved to your default database - simple!

But don't worry, you're not forced to use the current Git branch. You can also specify a name at any point, or manually use the default branch.

Using a specific database

To use a specific database, simply pass the name of the database to use:

Now, when using your app, it will be connected to the foobar database.

Using the default database

To use the default database, pass the --d option to the command:

Now, your app simply uses the default database as is set up in Laravel.

Hopper steps aside when the default database is used; it doesn't touch your database connection. This is useful for team members who might not want to use Hopper themselves. They can rest assured that Hopper isn't interfering with their setup.

Post Creation

When it is the first time using a database, Hopper will create it ready to use. Likely, you'll want to migrate and setup up this database. Hopper provides a clean way to run Post Creation Steps - see how you can set these up.

hop:current

See the database that you are currently using:

hop:delete

Delete the given database:

When a database is deleted, you will be moved back to your default database.

Configuration

As stated in setup, you don't need to publish the hopper config file to use Hopper. The config file is as so:

We'd encourage to checkout all the options described below to see if you want to publish it or not.

Default Git Branch

You should define here the name of the default git branch in your project:

Now, every time you hop on this branch without arguments, your default database will be used automatically - rather than a database called main.

You'll see that there is a HOPPER_DEFAULT_BRANCH .env variable available too - this means you can alter this value without publishing the config file.

Connections

Currently, Hopper has built in support for sqlite and mysql database connections. Hopper will automatically use whichever connection you are using.

These and future drivers are exposed and configured in the config file - which means you can add your own even if Hopper doesn't yet support it natively! See the supported connections in hopper.php:

Sqlite

Hopper stores all Sqlite databases within a relative directory in the database directory of your application. You can configure the name of the directory in the config file:

So, as you might expect, all temporary databases created by Hopper will be stored in database/hopper/. So for example, running this command...

...will create a sqlite database at database/hopper/test.sqlite.

The hopper directory will be created by Hopper if it doesn't already exist

All database names passed to hopper when using Sqlite will be sanitized. Slashes will be automatically converted to dashes for the Sqlite connection. So for instance, hop this/database will create a database called this-database.sqlite

It's probably worth adding your chosen directory to your .gitignore when using the sqlite connection!

MySql

Hopper creates all MySql databases on your configured MySql connection. All databases created will have a prefix applied to their name so you can easily identify them as needed. You can configure the prefix in the config file:

So for example, running this command...

...will create a MySql database called hopper_test.

All database names passed to hopper when using MySql will be sanitized. Dashes will be automatically converted to underscores for the MySql connection. So for instance, hop this-database will create a database called hopper_this_database

Adding your own

Hopper makes it nice and easy to add your own connection for a database type this is supported by Laravel but not by Hopper.

To add your own connection, create a class that implements the Connection interface. You can refer to the existing connections to see how to build your new implementation. When you are ready to implement it, add it to the connections array:

Boot Checks

Hopper exposes the checks it runs prior to wiring up your database connection. This way, you can alter the existing checks and/or add your own if needed. They are found in the hopper.php config file:

The included Environment check ensures the app environment is local. To add your own, ensure your class either implements the BootCheck interface or exposes a check() method which returns a boolean. Then, pop the class name in this array and you're all set.

Post Creation Steps

It is super simple to configure the steps you want to run after creating a new database.

The steps can be found in the hopper.php config file:

All strings included in this array must refer to an Artisan command in your app.

Closures can also be defined:

All steps are run in order of declaration, so ensure you migrate your database before any seeders!
