Compiling code and deploying static view files in magento2

Code compilation

To compile the code in magento2, we use setup:di:compile command which performs the following tasks :

Application code generation – for factories, proxies
Interceptor generation – improve code generation of interceptors
Interception cache generation – improve cache generation of interceptors
Area configuration aggregation – improve dependency injection configurations per area
Repositories code generation – create code for APIs
Service data attributes generation – create extension classes for data objects

Switch to the magento root folder (it is generally public_html) and run the above command -

bin/magento setup:di:compile

The above command will show the output as below.

Deploying static assets

The deployment commands of static view files enable us to write static files to the Magento 2 file system. These static view files are located in Magento’s static directory (your Magento2 install dir/pub/static) and some files are cached in your Magento 2 install dir/var/view_preprocessed directory.

For deployment of static view files, follow these steps:

Log in to your Magento 2 server as, or switch to, the Magento 2 file system owner.
Delete the content under <your Magento install dir>/pub/static.
Run the static view files deployment tool <your Magento install dir>/bin/magento setup:static-content:deploy.

Use the following commands to deploy static view files :

cd pub/static && find . -depth -name .htaccess -prune -o -delete && cd ../..
rm -rf var/cache/* var/view_preprocessed/* generated/* pub/static/* var/page_cache/* var/composer_home/*
php bin/magento setup:static-content:deploy -f
chmod -R 777 pub/static

Flush the magento cache using the above commands to make the site load fresh content -

bin/magento cache:clean
bin/magento cache:flush
