Failing to build from example

[psychemedia]

Hi

I'm a complete typescript novice and was trying to rebuild a working blog from this repo to explore using the sqlite components.

After installing TypeScript (npm install typescript) I tried the yarn build command but it failed on:

client/pages/index.tsx:3:21 - error TS2307: Cannot find module '../../posts-built/summary.json' or its corresponding type declarations.

Chasing dow the errors, I created an empty posts-built/summary.json file, then one with the contents {"posts":[]}, but it still wants more; does a schema, or some such, for that object need defining somewhere to be able to run the build?

Hey!

as a disclaimer: This repo isn't really made for public usage so I probably won't really add good documentation or really support working on it. You're probably better off using the sqlite repo directly and building your own simple UI.

You should not npm install typescript, instead you should run yarn install to install all dependencies. The summary.json file should be built by doing yarn posts which should automatically run as part of yarn build (see package.json)

Thanks... I appreciate that it isn't really a "public" repo - I was just trying to find a quick way over a coffee break to set up trying out your sqlite components as a sketch to demonstrate how interactive sqlite queries could be embedded, executed and response displayed in a web page.

I still seem to get some unresolved issues - I guess I need to put a bit more time aside to get a better understanding of all the frameworks involved. I love the SQLite demos, btw:-)
