Tips to make your angular app faster:

while importing your module using lazy loading helps

{ 𝑝𝑎𝑡ℎ: 'ℎ𝑜𝑚𝑒', 𝑐𝑜𝑚𝑝𝑜𝑛𝑒𝑛𝑡: 𝐻𝑜𝑚𝑒𝐶𝑜𝑚𝑝𝑜𝑛𝑒𝑛𝑡;}

To using loadChildren:

{𝑝𝑎𝑡ℎ: 'ℎ𝑜𝑚𝑒', 𝑙𝑜𝑎𝑑𝐶ℎ𝑖𝑙𝑑𝑟𝑒𝑛: './ℎ𝑜𝑚𝑒/ℎ𝑜𝑚𝑒.𝑚𝑜𝑑𝑢𝑙𝑒#𝐻𝑜𝑚𝑒𝑀𝑜𝑑𝑢𝑙𝑒'}

to make even better use dynamic import() function in Javascript.

{
𝑝𝑎𝑡ℎ: 'ℎ𝑜𝑚𝑒',
𝑙𝑜𝑎𝑑𝐶ℎ𝑖𝑙𝑑𝑟𝑒𝑛: () => 𝑖𝑚𝑝𝑜𝑟𝑡('./ℎ𝑜𝑚𝑒/ℎ𝑜𝑚𝑒.𝑚𝑜𝑑𝑢𝑙𝑒').𝑡ℎ𝑒𝑛(𝑚 =>
𝑚.𝐻𝑜𝑚𝑒𝑀𝑜𝑑𝑢𝑙𝑒)
},

import statement return a promise. you read more about in given link.
