Introduce Dart infrastructure for frontend2026-08-15T17:56:51Zxengineeringme@xengineering.eu2026-08-11T09:14:54Zurn:sha1:23b6e36df77cec673886dc924a73417885fe4535
The Dart programming language is excellent for frontend use. It is
suitable to write command line programs, web interfaces with the builtin
JavaScript transpiler and cross-platform applications with Flutter.
To focus on a small number of languages Dart should now be used for
frontend purposes as Go is used for backend purposes.
Thus it is a valid option to start the migration for Ceres from Go +
JavaScript to Go + Dart.
This commit sets up the infrastructure. A `view/dart/ceres.dart` file is
added together with tooling to transpile to JavaScript, embed it into
the Go executable and serve it. Furthermore the script which just prints
a message to the console is added to every page.
Further commits can move existing code to Dart or add new code in Dart.
Add JSON-based API under `/api`2026-08-15T17:56:51Zxengineeringme@xengineering.eu2026-08-13T18:53:24Zurn:sha1:53a5b271eae38913307793fa9884856709c4f822
This commit provides an unstable JSON API for communication with an
upcoming Dart frontend.
Later it might be part of the public interface for integration into
other services. For this step it has to be ensured the semantics are not
changing a lot in the future which is currently out of scope.
view: Implement favorite recipes2024-11-03T15:06:58Zxengineeringme@xengineering.eu2024-11-03T14:50:08Zurn:sha1:c1b976edd0c27fdc488da7ff4c1b7551df0323cd
This marks favorite recipes with a `⭐` emoticon. The favorite flag
value can be set on the recipe edit page. Favorite recipes are listed
first on the recipe list view.
Furthermore as a second priority the created time stamp is used in the
recipe list so that more recent recipes are listed first.

This makes the recipe page less pretty. Nevertheless the URL is more
visible to the user which makes it more likely that errors in the URL
are detected.
This change is based on user feedback. Invalid URLs were added which led
effectively to data loss.

This makes it easier to write a shopping list for the required
ingredients.
Switch to http.Handler2024-10-23T18:34:57Zxengineeringme@xengineering.eu2024-10-23T18:34:57Zurn:sha1:e66691083a2455c29b50a2970c0aba1d6afca753
The used `func(http.ResponseWriter, *http.Request)` return values made
the HTTP handler factory functions quite unreadable. Thus it is switched
to the http.Handler type.
Remove github.com/gorilla/mux dependency2024-10-22T19:53:30Zxengineeringme@xengineering.eu2024-10-22T19:17:47Zurn:sha1:dbc874e2b9f300bea7a18deda32e784afb0ab89a
The reason for the introduction of this dependency was that it was easy
to setup routes with HTTP method restrictions.
Since Go 1.22 this feature is part of the standard library. Method
restrictions are part of the patterns used to register routes [1].

model: Replace global db variable by custom type2024-10-13T17:55:38Zxengineeringme@xengineering.eu2024-10-13T17:52:28Zurn:sha1:473052ed8f2c83052ed5b47a7f4cec68ac2621a6
Reducing global variables makes it easier to understand functions
independently of the rest of the code.
Adding the new model.DB type as a custom variant of the sql.DB type
makes it possible to write methods for the database which makes the code
way more readable.
model: Fix direct access to database2024-10-12T13:24:33Zxengineeringme@xengineering.eu2024-05-17T20:49:15Zurn:sha1:9d3a5fb85dc02e87fab879855c4c3bace5f753f2
Instead a database transaction has to be used. Each database interaction
should be wrapped into a transaction to make sure any possible change
(even side-effects) can be rolled back in case of errors.
Apply go fmt to all source files2024-09-11T18:25:54Zxengineeringme@xengineering.eu2024-09-11T18:25:31Zurn:sha1:54029aac92f17ec87d3ef0bb73fcdac271b209c9

The recipe edit page HTML template did not contain the two time stamps
"Created" and "LastChanged" as hidden form values.
Thus the information was not passed from the backend to the frontend. On
a save the recipe without time stamp information was injected into the
backend.
This effectively deleted any time stamp information. This commit fixes
that bug by including all fields of the model.Recipe struct inside the
form of the recipe-edit.html template.

This accepts only real numbers with a minimum step of 0.001 as input for
the amount field of a recipe ingredient.
The browser has the chance to give the user direct feedback that a
non-numeric string will not work.

If the recipe has no ingredients at all the "Ingredient summary:" text
used to be displayed. This is not useful and confusing. It is removed
with this commit.

It does make sense to add an ingredient only with a type and no amount
or unit like 'salt'. But it does not make sense to add an ingredient
without a type like '5' or '2 l'.

This used to be named 'Ingredients: which might be confusing since
ingredients are defined per step and the list at the top of the recipe

This supports using Ceres without a mouse and only with tab-based
navigation with a keyboard.

This makes the JS function way simpler and removes a duplication of the
step HTML code.
