Sometimes Express is a bit too fast when you're working locally. Express Tortoise can be used to slow things down, simulating a production server's response time.
- Slow down requests using a min/max range
- Enable/disable based on your environment
- Optional logging to display the delay duration for each response
- Small footprint, zero dependencies
npm install express-tortoise
const app = require('express')();
const tortoise = require('express-tortoise');
// All params are optional
app.use(tortoise({
enabled: process.env.NODE_ENV === 'development',
log: 'Response delayed to simulate production (%s ms)',
min: 250,
max: 750
}));enabled(bool) - Set to true to slow down responses or false to disable the delay, default true.log(string|false) - If this is a string, a message will be logged to the console with each response. Use%sas a placeholder for the delay in ms. Set to false to disable logging.min(int) - The minimum possible delay in ms, default 250.max(int) - The maximum possible delay in ms, default 750.
