As you’re probably aware, apps cost money to make and maintain, even if they aren’t paid software. They take time to develop, and they cost more than they do in the short term to maintain and update later on. With that being said, making smart decisions upfront can help reduce the costs of maintaining your app, later on, so you can spend less money on it or avoid it altogether! Here are 5 ways to reduce the maintenance costs of your ReactJS app!
The first thing you can do is make sure that you are using the latest dependencies. When you have a dependency that has known vulnerabilities, it's important to update it as soon as possible. It's also a good idea to keep your dependencies up-to-date for security purposes. If you're using a dependency but not using it in many places, consider removing it altogether. Often times these unused libraries come with other code you may be able to remove, making your app lighter and more performant.
An important step before deploying is running npm shrinkwrap and updating any packages with new versions available (assuming npm v3). This will ensure that all dependencies are included when deploying and there aren't any surprises later on.
One thing that you can do is use code splitting. Code splitting allows you to break your code into smaller pieces and load them on demand, and with React's create-react-app, it's as easy as adding a single line of configuration. This will help ensure that your app will only load what it needs when it needs it.
One way to reduce app maintenance costs is through proper caching. When your application first loads, you can cache any API calls or any other data retrieval that takes a significant amount of time. This will help cut down on how often your server needs to be accessed, which will in turn result in reduced bandwidth usage and less load on your server. When using React with Redux, use immutability: If you’re using Redux with React, it’s important to use immutability with your state.
Minimize the number of dependencies. The more dependencies you have, the more complex your app becomes. In general, you should aim for less than 20 dependencies. One way to accomplish this is by using a library like Webpack's Loaders which can require() or import() modules on demand. This means that if you don't use a module, it won't be included in your bundle, reducing complexity and dependency count.
One way to reduce maintenance costs is by automating as much as possible. This will help reduce errors that might occur with your app. Here are a few ways you can automate your app:
- Use automated tests for any new features or functionality added. - Write scripts for repetitive tasks. - Create tools and utilities for development, testing, deployment, etc., that can be reused across projects and teams.
