• backend - dotnet API
• backend/FwLite - FieldWorks lite application
• frontend - SvelteKit app
• hgweb - hgweb Dockerfile and config
• otel - Open Telemetry collector config
• deployment - k8s config for production, staging, develop and local development environments

files related to a specific service should be in a folder named after the service. There are some exceptions:

• LexBox.sln visual studio expects the sln to be at the root of the repo and can make things difficult otherwise

Other files, like skaffold.yaml, should be at the root of the repo, because they're related to all services.

• docker and compose
  • enable Kubernetes in the Docker Desktop settings

• install Taskfile
  • windows: winget install Task.Task
  • linux: sudo snap install task --classic or other options on their website
  • mac: brew install go-task/tap/go-task
  • via npm: npm install -g @go-task/cli
• install Skaffold and add it to your path
• clone the repo
• run setup task setup, which:
  • initializes a local.env file
  • tells Git to use our ignore revs file
  • downloads the FLEx repo for the project seed data

If you're running Windows, you may need to add the following lines to your C:\Windows\system32\drivers\etc\hosts file:

127.0.0.1 resumable.localhost
127.0.0.1 hg.localhost
127.0.0.1 admin.localhost

On Linux, anything with a .localhost domain is automatically mapped to 127.0.0.1 so you don't need to edit your /etc/hosts file.

task up

The full app will be running at https://localhost after everything starts. There are some additional urls below to access specific parts of the system.

• The SvelteKit UI requires: node v20+
• The .NET API requires: dotnet sdk v8+

There are various ways to run the project. Here are a few suggestions:

For developing the .NET API

• task infra-up starts all necessary infrastructure in k8s
• task api:only starts the api locally

For developing the SvelteKit UI

1. In two seperate consoles:

• task backend-up starts all necessary infrastructure + the .NET API in k8s
• task ui:only starts the ui locally

1. In a shared console:

• task ui-dev

The SvelteKit UI will be available at https://localhost:3000.

For developing the .NET API and the SvelteKit UI

• task infra-up starts all necessary infrastructure in k8s
• task api:only starts the api locally
• task ui:only starts the ui locally

If the k8s deployments are already running

• infra-forward forwards the infrastructure ports for the API
• backend-forward forwards the infrastructure + backend ports for the UI

• https://localhost - k8s ingress
• https://localhost:3000 - SvelteKit UI
• https://localhost:5158/api - .NET API
• https://localhost:5158/api/swagger - .NET Swagger UI
• https://localhost:5158/api/graphql - GraphQL API
• https://localhost:5158/api/graphql/ui - GraphQL UI
• https://localhost:8088/hg - hg web UI (add the project code and use the url in FLEx to clone)
• https://localhost:1080 - maildev UI
• https://localhost:4810 - pgadmin UI (username [email protected], password pass)
• https://localhost:18888 - aspire dashboard (OTEL traces)

Once the database is created by the dotnet backend, it will also seed some data in the database. The following users are available, password for them all is just pass:

• [email protected]: super admin
• [email protected]: project manager
• [email protected]: project editor
• [email protected]: user without any projects

There will also be a single project, Sena 3. There will not be an hg repository however, see optional setup below if this is desired.

This project is instrumented with OpenTelemetry (OTEL). The exported telemetry data can be viewed in Honeycomb.

For your local environment to send traces to Honeycomb, you will need to set the HONEYCOMB_API_KEY environment variable in the deployment/local-dev/local.env file. You can get the key from here.

Traces can be accessed directly with a URL like this: https://ui.honeycomb.io/sil-language-forge/environments/[test|staging|prod]/trace?trace_id=_TRACE_ID_. Yes, bookmark it!

In the application, a trace ID (aka "Error code") shown at the bottom of an error message can be Ctrl+clicked to navigate to the trace in Honeycomb.
