|
| Does it include an autogenerated admin page like Django?
|
| Does it handle database migrations?
|
| You mention both Vue and React in your page, does that mean I

| that?
|
| What are the limitations of the query builder?

| 1. I'm working on the admin panel, but it's not yet ready. I'm

| introducing too many abstractions. Generally speaking, I'd like
| to avoid ORMs as much as possible. :) 2. I use the node-pg-
| migrate [1] for migrations at the moment, but I plan to tightly
| integrate with Postgraphile / Hasura to give another approach
| for that part. 3. You need to add them manually, but the
| architecture is pretty close to Vite [2]. You have just one
| Node process for both front-end & back-end: in development I
| compile assets on the fly using ESBuild [4], in production I
| bundle them using Rollup. I should probably describe that in
| the docs more clearly :) In contrast to Vite, Kretes also
| provide a REST API out-of-the-box, and a relatively simple path
| for adding a GraphQL endpoint. 4. The current query builder -
| sqorn [5] - has a nice syntax as it uses the same vocabulary as
| SQL, but it's not typed. My goal is to create a fully typed
| TypeScript query builder that's adapted _only_ for PostgreSQL.
| Here 's the preliminary work for that [3] 5. I'm still working
| on the docs. I'll fix the things you mentioned right away.

| Hey HN, author here. Kretes is a tool for building full-stack
| applications in TypeScript and PostgreSQL with a goal to provide
| an integrated, battery-included and open-source solution for web
| development. It combines a web framework - similar to Rails,
| Django or Laravel - with a UI being built on top of the VS Code
| editor. It comes with a (eventually large) standard library of
| built-in modules that are developed in a coherent way e.g.
| authentication, authorization, admin panel [1] etc.
|
| This project explores the ideas introduced by the Self
| programming language and aims to bring them to the current age.
| The ultimate goal is to create a semi-visual tool for building
| web apps in a more intuitive way using just one programming
| language - TypeScript - on the client & on the server, and
| without the accidental complexity.
|
| The project started as a way to arrange my knowledge around
| JavaScript. Inspired by the past, I decided to replicate to some
| extend what Sun Microsystems did in '95 with the Self programming
| language (a project I find underrated and ahead of its time), but
| using modern, popular tools such as JavaScript/TypeScript, VS
| Code, WebAssembly, PostgreSQL, etc.
|
| The project is in early alpha stage with the bus factor of
| (strong) 1. :)
|
| Happy to answer any questions here or at oh@zaiste.net*
|
| _PS. I'm creating a todo app using Kretes on YouTube [2] to
| explain the bigger picture of building full-stack applications.
| IMHO it's good to have a general understanding of how web
| applications work_ before* specializing in front-end or back-end
| - that's the goal for this video series, and for Kretes.

| For those of us unaware of what the Self programming language
| is/was, what things did you find inspiring that you are using
| in this framework?

|
| I must mention DarkLang [2] that seems to have a similar
| goal, but a different approach: Kretes builds on top of VS
| Code, and uses one of the most popular programming languages
| while DarkLang builds not only their editor from scratch, but
| they also introduced a new programming language. I find their
| project ambitious and inspiring - a potential game changer
| imho

| Nestjs has been around or a while and support a ton of tranports

| Congrats!
|
| I see that Kretes uses Sqorn [1] for talking to the database.
|
| I really like the looks of Sqorn, however iiuc, it doesn't
| support typescript right?
|
| How does that piece work?

| Hey Zaiste! I missed your name as OP :)
|
| That looks like a really good start. Do you think it'll end

| things like aggregations and perhaps even things like:
| `SELECT 1, 'hello'` to work. That would be the ultimate test!
|
| Happy to help with any Hasura integrations whenever you're
| ready too! Let's chat again soon. :)

| Wow! That would be awesome. I'd like to finish with the on-the-

|
| I also plan to rewrite the core to Deno. It will be relatively
