Gravitational Web Applications and Packages

This directory contains the source code for:

The code is organized in terms of independent yarn packages which reside in the packages directory.

Getting Started with Teleport Web UI

You can make production builds locally or you can use Docker to do that.

Local Build

Make sure that you have Yarn 1 installed. The Node.js version should match the one reported by executing make -C build.assets print-node-version from the root directory.

Then you need to download and initialize JavaScript dependencies.

yarn install

You will also need the following tools installed:

  • The Rust and Cargo version in build.assets/Makefile (search for RUST_VERSION) are required.
  • The wasm-pack version in build.assets/Makefile (search for WASM_PACK_VERSION) is required: curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
  • binaryen (which contains wasm-opt) is required to be installed manually on linux aarch64 (64-bit ARM). You can check if it's already installed on your system by running which wasm-opt. If not you can install it like apt-get install binaryen (for Debian-based Linux). wasm-pack will install this automatically on other platforms.

To build the Teleport open source version

yarn build-ui-oss

The resulting output will be in the webassets folder.

Docker Build

To build the Teleport community version

make docker-ui

Getting Started with Teleport Connect

See README.md in packages/teleterm.

Development

Local HTTPS

To run vite for either Teleport or Teleport enterprise, you'll need to generate local self-signed certificates. The recommended way of doing this is via mkcert.

You can install mkcert via

brew install mkcert

After you've done this, run:

mkcert -install

This will generate a root CA on your machine and automatically trust it (you'll be prompted for your password).

Once you've generated a root CA, you'll need to generate a certificate for local usage.

Run the following from the web/ directory, replacing localhost if you're using a different hostname.

mkdir -p certs && mkcert -cert-file certs/server.crt -key-file certs/server.key localhost "*.localhost"

(Note: the certs/ directory in this repo is ignored by git, so you can place your certificate/keys in there without having to worry that they'll end up in a commit.)

Certificates in an alternative location

If you already have local certificates, you can set the environment variables:

  • VITE_HTTPS_CERT (required) - absolute path to the certificate
  • VITE_HTTPS_KEY (required) - absolute path to the key

You can set these in your ~/.zshrc, ~/.bashrc, etc.

export VITE_HTTPS_CERT=/Users/you/certs/server.crt
export VITE_HTTPS_KEY=/Users/you/certs/server.key

Web UI

To avoid having to install a dedicated Teleport cluster, you can use a local development server which can proxy network requests to an existing cluster.

For example, if https://example.com:3080 is the URL of your cluster then:

To start your local Teleport development server

PROXY_TARGET=example.com:3080 yarn start-teleport

If you're running a local cluster at https://localhost:3080, you can just run

yarn start-teleport

This service will serve your local javascript files and proxy network requests to the given target.

Keep in mind that you have to use a local user because social logins (google/github) are not supported by development server.

WASM

The web UI includes a WASM module built from a Rust codebase located in packages/teleport/src/ironrdp. It is built with the help of wasm-pack.

Running yarn build-wasm builds the WASM binary as well as the appropriate Javascript/Typescript bindings and types in web/packages/teleport/src/ironrdp/pkg.

Unit-Tests

We use jest as our testing framework.

To run all jest unit-tests:

yarn run test

To run jest in watch-mode

yarn run tdd

Interactive Testing

We use storybook for our interactive testing. It allows us to browse our component library, view the different states of each component, and interactively develop and test components.

To start a storybook:

yarn run storybook

This command will open a new browser window with storybook in it. There you will see components from all packages so it makes it faster to work and iterate on shared functionality.

Browser compatibility

We are targeting last 2 versions of all major browsers. To quickly find out which ones exactly, use the following command:

yarn browserslist 'last 2 chrome version, last 2 edge version, last 2 firefox version, last 2 safari version'

Setup Prettier on VSCode

  1. Install plugin: https://github.com/prettier/prettier-vscode
  2. Go to Command Palette: CMD/CTRL + SHIFT + P (or F1)
  3. Type open settings
  4. Select Open Settings (JSON)
  5. Include the below snippet and save:
    // Set the default
    "editor.formatOnSave": false,
    // absolute config path
    "prettier.configPath": ".prettierrc",
    // enable per-language
    "[html]": {
        "editor.formatOnSave": true,
        "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "[javascript]": {
        "editor.formatOnSave": true,
        "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "[javascriptreact]": {
        "editor.formatOnSave": true,
        "editor.defaultFormatter": "esbenp.prettier-vscode",
    },
    "[typescript]": {
        "editor.formatOnSave": true,
        "editor.defaultFormatter": "esbenp.prettier-vscode"
    },
    "[typescriptreact]": {
        "editor.formatOnSave": true,
        "editor.defaultFormatter": "esbenp.prettier-vscode",
    },
    "[json]": {
        "editor.formatOnSave": true,
        "editor.defaultFormatter": "vscode.json-language-features"
    },
    "[jsonc]": {
        "editor.formatOnSave": true,
        "editor.defaultFormatter": "vscode.json-language-features"
    },
    "[markdown]": {
        "editor.formatOnSave": true,
        "editor.defaultFormatter": "esbenp.prettier-vscode",
    },
    "editor.tabSize": 2,

MFA Development

When developing MFA sections of the codebase, you may need to configure the teleport.yaml of your target teleport cluster to accept hardware keys registered over the local development setup. Webauthn can get tempermental if you try to use localhost as your rp_id, but you can get around this by using https://nip.io/. For example, if you want to configure optional webauthn mfa, you can set up your auth service like so:

auth_service:
  authentication:
    type: local
    second_factor: optional
    webauthn:
      rp_id: proxy.127.0.0.1.nip.io

proxy_service:
  enabled: yes
  # setting public_addr is optional, useful if using different port e.g. 8080 instead of default 3080
  public_addr: ['proxy.127.0.0.1.nip.io']

Then start the dev server like PROXY_TARGET=https://proxy.127.0.0.1.nip.io:3080 yarn start-teleport and access it at https://proxy.127.0.0.1.nip.io:8080.

Alternatively, if you have entries for your cluster in /etc/hosts and your cluster is configured to use something like teleport.test:3080 as the public address of the proxy service, you can just set a proxy target to that public address. Then instead of accessing the Vite proxy at localhost:8080, you can access it at teleport.test:8080. MFA will work fine since RP ID will still be teleport.test.

Adding Packages/Dependencies

We use Yarn Workspaces to manage dependencies.

The easiest way to add a package is to add a line to the workspace's package.json file and then run yarn install from the root of this repository.

Keep in mind that there should only be a single yarn.lock in this repository, here at the top level. If you add packages via yarn workspace <workspace-name> add <package-name>, it will create a packages/<package-name>/yarn.lock file, which should not be checked in.

Adding an Audit Event

When a new event is added to Teleport, the web UI has to be updated to display it correctly:

  1. Add a new entry to eventCodes.
  2. Add a new entry to RawEvents using the event you just created as the key. The fields should match the fields of the metadata fields on events.proto on Teleport repository.
  3. Add a new entry in Formatters to format the event on the events table. The format function will receive the event you added to RawEvents as parameter.
  4. Define an icon to the event on EventIconMap.
  5. Add an entry to the events array so it will show up on the AllEvents story
  6. Check fixture is rendered in storybook, then update snapshot for Audit.story.test.tsx using yarn test-update-snapshot.

You can see an example in this pr.
