In this article, we can try to Install and Configure the Session package, how to install and configure the Session package for AdonisJS, Config the Session package, and configure the Session package and Usage.<\/p>\n
Firstly, the support for sessions is provided by the @adonisjs\/session<\/strong> package. This Session package comes pre-configured with the web starter template.<\/p>\n Install<\/strong><\/p>\n You can check our previous article:\u00a0AdonisJS: REST API simple CRUD Operation<\/a>. IF you want then buy a good, reliable, secure web\u00a0hosting<\/a>\u00a0service \u00a0from here:\u00a0click here<\/a><\/em><\/strong> Validate environment variables<\/strong><\/p>\n So, you can configure the behavior of the session by tweaking the config\/session.ts<\/strong> file for your project. Following below is the default config file.<\/p>\n And the session package allows you to choose between one of the available drivers to save the session data on your own projects.<\/p>\n So, you can configure the driver inside the config\/session.ts<\/strong> file and the driver property, in turn, relies on the SESSION_DRIVER<\/strong> environment variable.<\/p>\n Hence the cookie driver also works great even when your application or project is behind a load balancer since it will no information is stored on the server.<\/p>\n So, you can pinch the settings for the cookie driver inside the config\/session.ts<\/strong> file.<\/p>\n Therefore, the file driver stores the session data on the server filesystem and you can configure the storage location by updating the value of the file.location<\/strong> property inside the config\/session.ts<\/strong> file for your application or project.<\/p>\n Now, the configuration for the redis<\/strong> driver references one of the pre-defined redis<\/strong> connections inside the config\/redis.ts<\/strong> file in your projects.<\/p>\n Next, you can define a connection named local inside the config\/redis.ts<\/strong> file to your project.<\/p>\n So, you can interact with sessions by using the ctx.session<\/strong> property.<\/p>\n After then, here read-only version of the session is also available inside the Edge templates and you can access it using the session global helper.<\/p>\n After, read the value for a given key from the session store. Because you can define a default value to return when the actual value is undefined or null.<\/p>\n Now, write a key-value pair to the session store for the value should be one of the cookie-supported data types<\/a><\/strong>.<\/p>\n Now, read everything from the session store and you Will always be an object of a key-value pair.<\/p>\n Now remove the value for a given key from the session store.<\/p>\n Now, Increment the value for a given key and Make sure the original value is always a number. The Calling increment<\/strong> on a non-numeric value will result in an exception.<\/p>\n But, Decrement the value for a given key and Make sure the original value is always a number. The Calling decrement<\/strong> on a non-numeric value will result in an exception.<\/p>\n This is Clear the session store to an empty state.<\/p>\n session.clear()<\/p>\n Firstly, AdonisJS creates an empty session store and assigns it to a unique and separate session id on the first HTTP request, also even if the request\/response lifecycle doesn’t interact with sessions.<\/p>\n Secondly, Flash messages are stored inside the session store and are only available for the next HTTP request. Here you can use them for passing messages between HTTP requests. Check the given example below:<\/p>\n Here we can use some methods like flash, flashAll, flashOnly, flashExcept, reflash, reflashOnly, reflashExcept, and Accessing flash messages, we will discuss another article. Finally, if you need to know more about this topic then please go to the AdonisJS main website<\/a>.<\/p>\n If you enjoyed reading this article and have more questions please reach out to our\u00a0support team<\/a>\u00a0via live chat or\u00a0email<\/a>\u00a0and we would be glad to help you. we provide server\u00a0hosting<\/a>\u00a0for all types of need and we can even get your\u00a0server<\/a>\u00a0up and running with the service of your choice.<\/p>\n","protected":false},"excerpt":{"rendered":" In this article, we can try to Install and Configure the Session package, how to install and configure the Session package for AdonisJS, Config the Session package, and configure the Session package and Usage.
