create product migration file

                  php artisan make:migration create_products_table
                  

this will generate a file in database\migrations folder.

open the file 'create_products_table' and add required table fields

                  public function up()
                  {
                      Schema::create('contacts', function (Blueprint $table) 
                      {
                              $table->id();
                              $table->string('name');
                              $table->string('mobile_no');
                              $table->boolean('status');
                              $table->timestamps();
                      });
                  }

                  

Run The Migration

                  php artisan migrate
                

Rollback The Migration

                php artisan migrate:rollback
                

Adding/Updating Columns in Table

For e.g. Updating the column name we should run command like

                php artisan make:migration update_name_column_in_products_table
                

open the file 'update_name_column_in_products_table' and add the fields

                Schema::table('products', function (Blueprint $table) {
                  $table->index('email');
               });
              

For renaming a index you can use renameIndex() for e.g.

                Schema::table('products', function (Blueprint $table) {
                    $table->renameIndex('email', 'mobile_no');
               });
              

For dropping a index you can use dropIndex() for e.g.

                Schema::table('products', function (Blueprint $table) {
                  $table->dropIndex('email');
               });
