InstructLab UI Technical Overview

This is a NextJS framework with Patternfly UI library components.

Manually Running the React UI

Set the .env in the ui directory and run the following:

cd ui/
npm install
npm run dev
# or for prod
npm run build
npm run start

Other helpful NPM Commands

# Run a production build (outputs to ".next" dir)
npm run build

# Start the Next.js server (run a production build)
npm run start

# Lint the project
npm run lint

# Automatically fix linting issues
npm run lint:fix

# Format code using Prettier
npm run pretty

# Run type checking
npm run type-check

Make scripts

Podman is a requirement. Install and init instructions here.

# Run markdown linter
make md-lint

Deploying the UI stack on your local machine

Set the .env in the ui directory and make sure you uncomment the IL_UI_DEPLOYMENT=dev. Once .env file is setup, run the following:

make start-dev-local

This will start the UI and the dependent pathservice locally on the machine.

Note

It might ask for permission to allow to listen on port 4000.

To stop the the local dev environment run the following:

make stop-dev-local

Deploying the UI stack in KIND cluster

Set the .env in the ui directory and run the following:

make start-dev-kind

This will start the Kind cluster and deploy the UI stack related manifest files in the cluster.

To stop the Kind cluster and delete the UI stack related resources, run the following:

make stop-dev-kind

Use make help to see all the available commands.

OAuth Configuration

You can either set up the Oauth app in your GitHub account or use the user/pass defined in .env. To change those defaults, create the /ui/.env file and fill in the account user/pass with the following.

Example .env file.

Local Dev Chat Environment

1) Using the ilab command line tool

For the chat functionality to work you need a ilab model chat instance. To run this locally:

cd server

https://github.com/instructlab/instructlab?tab=readme-ov-file#-getting-started

After you use the ilab serve command you should have, by default, a chat server instance running on port 8000.

2) Using Podman

Current issues

  • The docker image that runs the server does not utilise Mac Metal GPU and therefore is very slow when answering prompts
  • The docker image is very large as it contains the model itself. Potential to have the model incorporated via a docker volume to reduce the size of the actual image.

docker run -p 8000:8000 aevo987654/instructlab_chat_8000:v2

This should run a server on port 8000

Configuring the chat environment to use a local ilab model chat instance

Return to the root of the repo (ui) and run npm run dev and visit http://localhost:3000/playground/endpoints.

Click the Add Endpoint button and a popup modal will appear.

enter image description here

  • URL - add http://127.0.0.1:8000
  • Model Name - add merlinite-7b-lab-Q4_K_M.gguf
  • API Key - add some random characters

Click the Save button

enter image description here

Go to the chat interface http://localhost:3000/playground/chat and select the merlinite-7b-lab-Q4_K_M.gguf model.

enter image description here

The chat interface should now use the server.

How to Cherry-Pick a Merged PR to release-1.0

Until we finish automating releases, you may be asked to cherry-pick your PR after it is merged. Here are instructions for cherry-picking a merged Pull Request to the release-1.0 branch.

Example:

  1. Identify the Commit Hash:

  • After a PR is merged, navigate to the main branch or the branch where the PR was merged.

  • Find the commit(s) related to the PR. You can identify the commit hash from the commit history in the GitHub UI or by using the git log command.

    Example:

    git log --oneline

Copy the commit hash of the PR that you want to cherry-pick.

{:start="2"} 2. Check Out the Release Branch:

  • Ensure you are working on the correct release branch (release-1.0 in this case).

    git checkout release-1.0

{:start="3"} 3. Create a New Branch:

  • Create a new branch based on the release-1.0 branch for your cherry-pick changes.

    git checkout -b cherry-pick-pr-<PR-number>-release-1.0

{:start="4"} 4. Cherry-Pick the Commit:

  • Use the git cherry-pick command to apply the specific commit to your new branch.

    git cherry-pick <commit-hash>

If there are multiple commits associated with the PR, repeat this command for each commit hash, or use the commit range if they are consecutive:

git cherry-pick <commit-hash-start>^..<commit-hash-end>

{:start="5"} 5. Resolve Conflicts (If Any):

  • If there are conflicts, Git will pause the cherry-pick process and allow you to resolve them manually.

  • After resolving, add the resolved files and continue the cherry-pick process:

    git add <resolved-file>
git cherry-pick --continue

    If for some reason you need to abort the cherry-pick, you can use:

    git cherry-pick --abort

{:start="6"} 6. Push the New Branch:

  • After successfully cherry-picking and resolving any conflicts, push your new branch to GitHub.

    git push origin cherry-pick-pr-<PR-number>-release-1.0

{:start="7"} 7. Create a Pull Request:

  • Navigate to your GitHub repository and create a new Pull Request from your cherry-pick branch (cherry-pick-pr-<PR-number>-release-1.0) into the release-1.0 branch.

How to Run Playwright tests locally

As a developer, you can add more integration (end to end tests) after you develop your feature. We use playwright as the automation test runner for executing integration tests on our app. To execute playwright tests locally run the following command:

npm run test:e2e

Make sure to export USERNAME and PASSWORD on your local development environment since we authenticate into the application using the auth credentials provided by the user from process.env variables. For example:

export USERNAME=foo
export PASSWORD=***

There are some configuration options that you can use while developing tests locally. Following feature flags provide certain functionalities out of the box:

  • Use --trace flag to on to record a trace during development mode.
  • Use --ui flag to run tests in UI mode.
  • Use --headed flag to run tests in headed mode.
  • Use --debug flag to launch debugging for all tests.
  • Use --last-failed to run only the tests that failed in the last test run.

In our tests since we want to authenticate into the application, there is a shared account that is used across the tests. This user.json is generated on the first test run under playwright/.auth folder, and is saved as an authentication state to apply and reuse across every test as an already authenticated user.

The configuration for playwright tests is defined in playwright.config file and we're running these tests on Chromium, WebKit and Firefox browsers. Playwright will run all projects by default, but you can use the --project command line option to run a single project.

If you'd like to run a specific single test, use the following command with the appropriate folder path to your test. Example: npx playwright test tests/routing.spec.ts. To get a detailed report of the completed tests, run npx playwright show-report and you'll get a detailed view.
