QUESTION

The state of Google Lovefield

Asked 2021-Mar-13 at 18:18

Google Lovefield is a JS relational database layer on top of IndexedDB: https://github.com/google/lovefield

In their FAQ, it is said to be (or have been) in use by gmail.

It seems to no longer be developed and hardly maintained, and while the docs are not bad, I couldn't find a lot of information / tutorials for it.

I also didn't find information on whether it has been abandoned, or if it is continued or was transformed into another library.

If anyone has concrete information about the state of this library or derived products then I'll be happy to know.

According to comments from GitHub, it is in "long-term maintenance mode".
This means basically abandoned, but good enough for production for now. https://github.com/google/lovefield/issues/266#issuecomment-678883485

QUESTION

How to configure Angular-CLI-generated project to include a SharedWorker

Asked 2020-May-21 at 15:18

What are the specific steps to add a SharedWorker to an @angular/cli >1.2-generated project. I would like the SharedWorker to be defined in TypeScript (with full/correct type-definitions editor support), to share interfaces with the main project, and to be continuously compiled and tested along with the main project.

I haven't discovered an example or blog post that describes how to modify a cli-generated project to include either a Worker or a SharedWorker. However, there are several posts (such as this one) which show how to transform an entire cli-generated project to run it as a web worker. But that's not my use-case.

I want to confine interaction with a Lovefield database to a SharedWorker that runs in a separate process from the main application.

Though I've experimented a bit attempting to figure this out, I haven't made much progress. Hopefully someone can save me (and future readers) a lot of time.

Below code gives last message for a provided user id, but I want rows for all users.

Your query looks fine. Just remove the condition that filters on a specific user, and you should get the result that you expect:

Is there any client side Db library that supports partial text search?

Asked 2018-Apr-23 at 11:18

I am going thru IndexDB or lovefield but so far could not find way to search partial text like we do in SQL queries via LIKEkeyword. Can someone guide me how could it be achieved?

ANSWER

Answered 2018-Apr-23 at 11:18

lovefield has the match function for pattern matching which is similar to the SIMILAR keyword in SQL which inturn is similar to the LIKE keyword. Please have a look at it and see if it does the job
