sqlite3-sync

Synchronous Napi-bindings for libsqlite.

While the sqlite3-package for node.js is fine and usefull for server applications, its use tends to become overly complicated for simple scripting tasks..

So I immplemented a simple Napi based wrapper for libsqlite. Unlike other implementations, this package does not use libffi, mainly because i got into trouble using libffi on my target plattform. And just wrapping libsqlite myself seemed to be easier than tweaking or fixing foreign code.

Usage

Install the package via npm:

npm install sqlite3-sync

and use it:

let Sqlite = require('sqlite3-sync');
let db = Sqlte('my-db.sqlite');

db.each("SELECT name FROM customer", 
    (row) => { console.log(row.customer); },
    () => { console.log("eof); }
);

Api

let database = Sqlite(dbname, mode)

creates a database connection.

database.close()

close the database

row = database.get(sql_statment, arg_array)

prepares a statement, binds an array of arguments and returns the first resulting row.

list = database.all(sql_statment, arg_array)

prepares a statement, binds an array of arguments and returns the all resulting rows as an array.

database.run(sql_statment, arg_array)

prepares a statement, binds an array of arguments and runs the statement. This is equivalent to get()

database.exec(sql_statment, arg_array)

prepares a statement, binds an array of arguments and runs the statement. This is equivalent to get()

database.each(sql_statment, arg_array, function callback (row) => { }, function finally() => {} )

prepares a statement, binds an array of arguments and and opens a cursor for the query.

the callback is called once for each resulting row, after that the finally callback is called.

statement = database.prepare(sql_statment, opt_arg_array)

create a raw statemwnt object. This might be seldomly used, refer to index.js for further documention.
