# Hasura Console The Hasura console is an admin dashboard to manage the connected database and to try out GraphQL APIs. It is a React application bundled with webpack and the state is managed using Redux. Served by: 1. Hasura GraphQL Engine: The console is served by GraphQL Engine at `/console` endpoint (when `--enable-console` flag is used). Typically runs in **No Migration Mode** which means that actions on the console are not spitting out migration “yaml” files automatically. Most users will be using the Hasura console in this mode. 2. Hasura CLI: Served by the Hasura CLI using `hasura console` command, typically runs with migration mode **enabled**. All the changes to schema/hasura metadata will be tracked and spit out on the filesystem as migration yaml files and a metadata yaml file. This allows for easy version controlling of the schema/hasura metadata. ## Contributing to Hasura console This guide is for setting-up the console for development on your own machine, and how to contribute. ### Console issues in the repo Issues in the repo for the console UI are labelled as `c/console`(see [list](https://github.com/hasura/graphql-engine/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen++label%3Ac%2Fconsole)). Issues also labelled as `good first issue` are aimed at those making their first contribution to the repo (see [list](https://github.com/hasura/graphql-engine/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen++label%3Ac%2Fconsole+label%3A%22good+first+issue%22)). Others marked as `help wanted` are those requiring community contributions on priority (see [list](https://github.com/hasura/graphql-engine/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen++label%3Ac%2Fconsole+label%3A%22help+wanted%22)). Please note that some of these issues, labelled with both `c/console` and `c/server`, are part of a change/task that requires modifications in both the server and the console. Feel free to open pull requests to address these issues or to add/fix console features, even if a corresponding issue doesn't exist. If you are unsure about whether to go ahead and work on something like the latter, please get in touch with the maintainers in the `GraphQL Engine`->`contrib` channel in the community [Discord](https://discord.gg/vBPpJkS). ### Prerequisites - [Node.js](https://nodejs.org/en/) (v8.9+) - [Hasura GraphQL Engine](https://hasura.io/docs/1.0/graphql/manual/getting-started/index.html) - [Hasura CLI](https://hasura.io/docs/1.0/graphql/manual/hasura-cli/install-hasura-cli.html) (for working with migrations) ### Set up and install dependencies - Fork the repo on GitHub. - Clone your forked repo: `git clone https://github.com//graphql-engine` ```bash git clone https://github.com//graphql-engine cd graphql-engine cd console npm ci ``` ### Run console development server Hasura console can be developed in two modes, `server` or `cli` mode. If you are looking to add/tweak functionality related to migrations, check out [Develop with Hasura CLI](#develop-with-hasura-cli-cli-mode), otherwise check out [Develop with Hasura GraphQL engine](#develop-with-hasura-graphql-engine-server-mode). Both modes require a running instance of GraphQL Engine. The easiest way to get Hasura GraphQL engine instance is by Heroku. You can get it by following the steps given in [this](https://hasura.io/docs/1.0/graphql/manual/getting-started/heroku-simple.html) link. Other methods to install Hasura GraphQL engine are documented [here](https://hasura.io/docs/1.0/graphql/manual/getting-started/index.html). [Dotenv](https://github.com/motdotla/dotenv) is used for setting environment variables for development. In production, these environment variables are templated by the server or CLI. #### Develop with Hasura GraphQL engine (`server` mode) In server mode, **migrations** will be disabled and the corresponding functionality on the console will be hidden. ##### Set up `.env` file Environment variables accepted in `server` mode: - `NODE_ENV`: Console build environment (`development`/`production`) - `PORT`: The port where Hasura console will run locally - `CDN_ASSETS`: Should assets be loaded from CDN (`true`/`false`) - `ASSETS_PATH`: Path to console assets - `ASSETS_VERSION`: Version of console assets being served - `ENABLE_TELEMETRY`: Whether to enable telemetry (`true`/`false`) - `URL_PREFIX`: Path at which the console is running - `DATA_API_URL`: The Hasura GraphQL engine url. (If you are running it on Heroku, it will look like https://.herokuapp.com, if you are running locally, it will look like http://localhost:) - `SERVER_VERSION`: Hasura GraphQL Engine server version - `CONSOLE_MODE`: In server mode, it should be `server` - `IS_ADMIN_SECRET_SET`: Is GraphQl engine configured with an admin secret (`true`/`false`) Here's an example `.env` file for `server` mode: ```bash NODE_ENV=development PORT=3000 CDN_ASSETS=true ASSETS_PATH=https://graphql-engine-cdn.hasura.io/console/assets ASSETS_VERSION=channel/stable/v1.0 ENABLE_TELEMETRY=true URL_PREFIX=/ DATA_API_URL=http://localhost:8080 SERVER_VERSION=v1.0.0 CONSOLE_MODE=server IS_ADMIN_SECRET_SET=true ``` > The server also templates `consolePath` in `window.__env` which is the relative path of the current page (something like `/console/data/schema/public`). Using this path, the console determines the DATA_API_URL in production. You do not need to worry about this in development since you are hardcoding the value of DATA_API_URL in `.env`. ##### Run console development server: ```bash npm run dev ``` #### Develop with Hasura CLI (`cli` mode) ##### Set up `.env` file Environment variables accepted in `cli` mode: - `NODE_ENV`: Console build environment (`development`/`production`) - `PORT`: The port where Hasura console will run locally - `API_HOST`: Hasura CLI host. Hasura CLI runs on `http://localhost` by default. - `API_PORT`: Hasura CLI port. Hasura CLI exposes the API at `9693` by default - `CDN_ASSETS`: Should assets be loaded from CDN (`true`/`false`) - `ASSETS_PATH`: Path to console assets - `ASSETS_VERSION`: Version of console assets being served - `ENABLE_TELEMETRY`: Whether to enable telemetry (`true`/`false`) - `URL_PREFIX`: Path at which the console is running - `DATA_API_URL`: The Hasura GraphQL engine url. (If you are running it on Heroku, it will look like .herokuapp.com, if you are running locally, it will look like http://localhost:) - `SERVER_VERSION`: Hasura GraphQL Engine server version - `CONSOLE_MODE`: In cli mode, it should be `cli` - `ADMIN_SECRET`: the admin secret passed via the CLI Here's an example `.env` file for `cli` mode: ```bash NODE_ENV=development PORT=3000 API_HOST=http://localhost API_PORT=9693 CDN_ASSETS=true ASSETS_PATH=https://graphql-engine-cdn.hasura.io/console/assets ASSETS_VERSION=channel/stable/v1.0 ENABLE_TELEMETRY=true URL_PREFIX=/ DATA_API_URL=http://localhost:8080 SERVER_VERSION=v1.0.0 CONSOLE_MODE=cli ADMIN_SECRET=my-admin-secret ``` ##### Run console development server: This setup requires a Hasura CLI console server to be running. ###### Start Hasura CLI console server Start Hasura CLI console with the same Hasura GraphQL engine url as configured for `DATA_API_URL`. ```bash hasura console --endpoint --admin-secret (optional) ``` ###### Start development console server ```bash npm run dev ``` ### Check out the console Visit [http://localhost:3000](http://localhost:3000) to confirm the setup.  ### Make changes to the code Make changes to the code and the console will reload automatically to reflect the new changes. Keep iterating. When adding a new feature, it is recommended to add corresponding tests too. Tests are written using [Cypress](https://www.cypress.io/). You can use the [Redux DevTools Extension](http://extension.remotedev.io/) to inspect and debug the Redux store. It should automatically connect to the Redux store when started in development mode. By default [redux-logger](https://www.npmjs.com/package/redux-logger) is enabled to assist in development. You can disable it if you wish by commenting out the `createLogger` line in `src/client.js` ### Run tests - Run tests: `npm run cypress` - Write your tests in the `cypress` directory, integration. ### Linter and formatter Pre-commit git-hook that runs linter and formatter is by default disabled. You can enable it by adding `HUSKY_PRE_COMMIT=true` to your `.env` file. If you want to run a linter for all files, you can do: ```bash npm run lint ``` To format all files, you can run: ```bash npm run format ``` ### Submitting a pull request - All the development work happens in your own fork of the graphql-engine. - Make sure your commit messages meet the [guidelines](../CONTRIBUTING.md#commit-messages). - Once the changes are done, create a pull request. - CI configured for PR will run the test suite. - Once everything goes well, it will generate a preview Heroku app. - The source code and the preview app will be reviewed by maintainers.
