Configuring Express Settings

Express provides several application settings that control the behavior of the Express server. These settings define the environment as well as how Express handles JSON parsing, routing, and views. Table 18.1 lists the settings that can be defined on an express object.

Table 18.1 Express application settings

The express object provides the set(setting, value) and enable(setting) and disable(setting) methods to set values for the application settings. For example, the following lines of code enable the trust proxy setting and set view engine to jade:

Click here to view code image

app.enable('trust proxy'),
app.disable('strict routing'),
app.set('view engine', 'jade'),

To get the value of a setting, you use the get(setting), enabled(setting), and disabled(setting) methods. For example:

Click here to view code image

app.enabled('trust proxy'),  \true
app.disabled('strict routing'), \true
app.get('view engine'), \jade
