Database file for wearable web application

Hi everyone,

I am developing a wearable web input method application, and I want to provide a candidate list containing the words predicted based on what user typed. Therefore I need a database. However, I found there is only indexedDB available, and I did not found any API that I can integrate my Database file into my application, I need to create the indexedDB from zero after I launch my application. Is there any way to have a database available right after the application is installed?

Indexed database API:

Another option is to use web storage, it stores key-value pairs. Very easy to use.

Finally, you can use filesystem to write your own "json" or "xml" files and read/write/update your data manually.

Hi,

Thank you for your answer, I have already read them all. So I think you mean I cannot have an existed database file ready for use right after the app is installed, and no matter which way I choose I need to create data using JavaScript first, is that correct?

Hi, from my findings the answer is yes.
