# Local Development

## Overview

Wails is in constant development and new releases are regularly "tagged". This usually happens when all the newer code on `master` has been tested and confirmed working. If you need a bugfix or feature that has not yet made it to a release, it's possible to use the latest "bleeding edge" version using the following steps:

- `git clone https://github.com/wailsapp/wails`
- `cd wails/v2/cmd/wails`
- `go install`

NOTE: The directory that you cloned the project into will now be called "clonedir".

The Wails CLI will now be at the very latest version.

### Updating your project

To update projects to use the latest version of the Wails library, update the project's `go.mod` and ensure the following line is at the bottom of the file:

`replace github.com/wailsapp/wails/v2 => <clonedir>`

Example:

On Windows: `replace github.com/wailsapp/wails/v2 => C:\Users\leaan\Documents\wails-v2-beta\wails\v2`

On 'nix: `replace github.com/wailsapp/wails/v2 => /home/me/projects/wails/v2`

To revert to a stable version, run:

`go install github.com/wailsapp/wails/v2/cmd/wails@latest`

## Testing a Branch

If you want to test a branch, follow the instructions above, but ensure you switch the branch you want to test before installing:

- `git clone https://github.com/wailsapp/wails`
- `cd wails`
- `git checkout -b branch-to-test --track origin/branch-to-test`
- `cd v2/cmd/wails`
- `go install`

Make sure you [update your project](#updating-your-project) as described above.

## Testing a PR

If you want to test a PR, follow the instructions above, but ensure you fetch the PR and switch the branch before installing. Please replace `[IDofThePR]` with the ID of the PR shown on github.com:

- `git clone https://github.com/wailsapp/wails`
- `cd wails`
- `git fetch -u origin pull/[IDofThePR]/head:test/pr-[IDofThePR]`
- `git checkout test/pr-[IDofThePR]`
- `git reset --hard HEAD`
- `cd v2/cmd/wails`
- `go install`

Make sure you [update your project](#updating-your-project) as described above.
