![]() If you only need to access the database on the back-end then just use node or python. If you need to access the database on the front-end you'll need to use something like the library I referenced in the previous comment. There's no access to the filesystem, and you can't run native binaries such as sqlite3. Browsers operate a kind of sandbox for executing JavaScript. In addition, you have seen a small real-world case study where I used a SQLite database to handle data from Twitter. In this tutorial, you have learned how to create SQLite databases and to manipulate tables using dot commands and SQL statements. So if you need this code to be executed client-side it will need to be JavaScript. That is why it is a good idea to use the DB Browser for SQLite in this instance. If you're talking about an Azure server then you'd run one of these on it.Īs for front-end, this is code that runs on your client's computer - for instance in the browser. SQLite is used in many, many devices world-wide. They can also execute natively compiled code. What a Database is, and what SQLite is Quick Installation How to create a Database using SQLite The basics of SQLite From this, you will be able create your own simple databases, and quickly be able to put them to use, when and where needed. They can be run from the command line, have access to the filesystem, can open SQLite files in one line, and can run a HTTP server. These are programs that run on your computer. I'll try to clarify a few misconceptions you have about front-end vs back-end though.įirstly, you have node and python, which deal with JavaScript and Python code respectively. Sorry for mis-understanding your problem in the first place. There's no need to over-engineer a problem if it can be solved simply. Menu.Action(func(opts wmenu.Opt) error )Īnd add the parameter to our function func handleFunc(opts wmenu.If python solves your problem then absolutely go ahead and use that. Menu := wmenu.NewMenu("What would you like to do?") This support is embedded in the file, meaning that any programming language that can use an SQLite file can also use SQL to work with it. Not only does an SQLite database file contain the data, but it also has a standardized way to interact with the data. Let’s create a main.go that looks like this: package main An SQLite database provides support for interacting with the data table using SQL. Install the WMenu package: go get /dixonwille/wmenu Create and open the deleteData.js file in your text editor: nano deleteData. In this section, you’ll use node-sqlite3 to select and delete a row from a table in the SQLite database. Step 6 Deleting Data in the SQLite Database. Next, you’ll delete data from the SQLite database. We won’t focus too heavily on the menu system itself because the intent of this article is to show you how to utilize SQLite.įirst, we’ll create a Go module and work with main.go to start. With that, you can now update a row in the database. If the file database.db already exists, Sqlite will open a connection to it if it does not exist, it will be created. Where ‘database’ is the name of your database. We’ll use this menu and a scanner to accept input to interact with our database. To create a database, run the command: sqlite3 database.db. I’m going to use The WMenu package from Dixonwille for this, so we have an interface for our data. We will build a CLI application that accesses a SQLite database. So let’s get started! Creating the menu system We’ll start by creating a menu, then building out methods for each operation, and in the end, you’ll have an application that looks like this: It has a database full of people with their first name, last name, email address, and IP address. I’ll start with pre-populated database you can download here. You can follow along and build this application or use this as a reference to build something of your own. We’ll build a CLI (command-line interface) application with Go and SQLite. So we’re going to combine these two technologies to show you how easy it is to marry the two. It’s ubiquitous in mobile phones and devices, and SQLite powers many websites today. In fact, you’re likely already using SQLite every day and you don’t know it. ![]() SQLite has been trending among developers for its ability to host small data very quickly, safely, and contained in a single file. Go is one of the hottest languages in development right now, known for its simple structure and blazing performance. By the time you finish this tutorial, you can build CRUD (Create Read Update Delete) applications with Go easily. Today we’re going to learn how to use SQLite with Go.
