# Vault UI

This README outlines the details of collaborating on this Ember application.

## Ember CLI Version Matrix

| Vault Version | Ember Version |
| ------------- | ------------- |
| 1.13.x        | 4.4.0         |
| 1.10.x        | 3.28.5        |
| 1.9.x         | 3.22.0        |
| 1.8.x         | 3.22.0        |
| 1.7.x         | 3.11          |

## Prerequisites

You will need the following things properly installed on your computer.

* [Git](https://git-scm.com/)
* [Node.js](https://nodejs.org/)
* [Yarn](https://yarnpkg.com/)
* [Ember CLI](https://cli.emberjs.com/release/)
* [Google Chrome](https://google.com/chrome/)
- [lint-staged\*](https://www.npmjs.com/package/lint-staged)

\* lint-staged is an optional dependency - running `yarn` will install it.
If don't want optional dependencies installed you can run `yarn --ignore-optional`. If you've ignored the optional deps
previously and want to install them, you have to tell yarn to refetch all deps by
running `yarn --force`.

In order to enforce the same version of `yarn` across installs, the `yarn` binary is included in the repo
in the `.yarn/releases` folder. To update to a different version of `yarn`, use the `yarn policies set-version VERSION` command. For more information on this, see the [documentation](https://yarnpkg.com/en/docs/cli/policies).

## Running a Vault Server

Before running Vault UI locally, a Vault server must be running. First, ensure
Vault dev is built according the the instructions in `../README.md`. To start a
single local Vault server:

- `yarn vault`

To start a local Vault cluster:

- `yarn vault:cluster`

These commands may also be [aliased on your local device](https://github.com/hashicorp/vault-tools/blob/master/users/noelle/vault_aliases).

## Running / Development

To get all of the JavaScript dependencies installed, run this in the `ui` directory:

- `yarn`

If you want to run Vault UI and proxy back to a Vault server running
on the default port, 8200, run the following in the `ui` directory:

- `yarn start`

This will start an Ember CLI server that proxies requests to port 8200,
and enable live rebuilding of the application as you change the UI application code.
Visit your app at [http://localhost:4200](http://localhost:4200).

If your Vault server is running on a different port you can use the
long-form version of the npm script:

`ember server --proxy=http://localhost:PORT`

To run yarn with mirage, do:

- `yarn start:mirage handlername`

Where `handlername` is one of the options exported in `mirage/handlers/index`

### Code Generators

Make use of the many generators for code, try `ember help generate` for more details. If you're using a component that can be widely-used, consider making it an `addon` component instead (see [this PR](https://github.com/hashicorp/vault/pull/6629) for more details)

eg. a reusable component named foo that you'd like in the core engine

- `ember g component foo --in lib/core`
- `echo "export { default } from 'core/components/foo';" > lib/core/app/components/foo.js`

### Running Tests

Running tests will spin up a Vault dev server on port 9200 via a
pretest script that testem (the test runner) executes. All of the
acceptance tests then run, proxing requests back to that server.

- `yarn run test:oss`
- `yarn run test:oss -s` to keep the test server running after the initial run.
- `yarn run test -f="policies"` to filter the tests that are run. `-f` gets passed into
  [QUnit's `filter` config](https://api.qunitjs.com/config/QUnit.config#qunitconfigfilter-string--default-undefined)

### Linting

- `yarn lint`
- `yarn lint:fix`

### Building Vault UI into a Vault Binary

We use the [embed](https://golang.org/pkg/embed/) package from Go 1.16+ to build
the static assets of the Ember application into a Vault binary.

This can be done by running these commands from the root directory run:
`make static-dist`
`make dev-ui`

This will result in a Vault binary that has the UI built-in - though in
a non-dev setup it will still need to be enabled via the `ui` config or
setting `VAULT_UI` environment variable.
