How to Serve Static Files (CSS, JS, Images) in Express JS?
Original answer fixed, see comments. Marko Kohtala Marko Kohtala 1 1 silver badge 10 10 bronze badges. Hi, ambroise.
Thanks for the comment. There indeed are some errors in my answer. Actual problem was perhaps that development server serves the app at root. Sign up or log in Sign up using Google.

In this post, we will go through how to structure a project and how to manage local assets. This of course is not written in stone, and you are free to apply only the pieces that suit you. Hope you learn something. For a project bootstrapped with react-native initwe get only the basic structure. There is the ios folder for Xcode projects, the android folder for Android projects, and an index. As someone who has worked with native on both Windows Phone, iOS and Android, I find that structuring a project all comes down to separating files by type or feature.
Separating by type means that we organise files by their type. If it is a component, there are container and presentational files. If it is Redux, there are action, reducer, and store files. This way, we can see the type of each file, and easily run a script toward a certain file type. Is it a loyalty app? Is it about nutrition tracking? Organising files by type is for a machine, not for a human.
Many times we work on a feature, and finding files to fix in multiple directories is a hassle. A more reasonable solution is to organise files by feature. Files related to a feature should be placed together.
And test files should stay close to the source files. Check out this article to learn more. A feature can contain sub-features as long as they belong to the same flow. If we wanted to move the sub feature around, it would be easy, as all related files are already grouped together. Besides the traditional files App. Inside src I have res for resources, library for common files used across features, and screens for a screen of content. Since React Native is heavily dependent on tons of dependencies, I try to be pretty aware when adding more.
How to structure your project and manage static resources in React Native
In my project I use just react-navigation for navigation. Only add a dependency when you really need it, otherwise you are just setting yourself up for more trouble than value.
Just a command and I have the files in src transpiled to dist in a blink. React is based around components. There are container and presentational componentsbut we can compose components to build more complex components.
They usually end in showing in the full screen. The React Native guide mentions screen very often as something that covers the entire space:. Each screen is considered the entry point for each feature.Sponsor webpack and get apparel from the official shop! All proceeds go to our open collective! The publicPath configuration option can be quite useful in a variety of scenarios. It allows you to specify the base path for all the assets within your application. There are a few use cases in real applications where this feature becomes especially neat.
Essentially, every file emitted to your output. This includes child chunks created via code splitting and any other assets e. This is fine, but what if we wanted to host all these static assets on a CDN in production?
To approach this problem you can easily use a good old environment variable. Another possible use case is to set the publicPath on the fly.
So, in your application's entry point, you can simply do this:. That's all you need. Since we're already using the DefinePlugin on our configuration, process. In such cases, you'll have to move the public path assignment to its own dedicated module and then import it on top of your entry.

Contributors rafaelrinaldi chrisVillanueva gonzoyumo.Let's start with an obvious statement: React application deployed to a subfolder will not work out of the box :. The reason for that is the path: React still tries to load its resources and assets from the root folder without accounting for a subdirectory. Sidetone: in the article, I'm using word assets for all static files as images, fonts, icons, etc.
Some guides suggest prepending every route and resource with process. Secondly, you might agree that the code becomes ugly and less flexible due to the fact of environment variable everywhere. Why not use the most elegant approach specifically designed to deal with such issues?
Convert all absolute links to relative ones. Base tag works only for relative URLs. The bare minimum plain HTML example :.
Conversion should be applied to all resources and assets. As was mentioned, this approach can be used for ajax calls if needed. If, for any reason, you don't want to load your asset or prepend path with subdir to the URL of ajax call, leave it absolute. If your images are outside of the src folder relative paths will not work correctly due to special restriction in ModuleScopePlugin implemented by create-react-app developers the more info here.
Set homepage in the package. This value is applied only for the production build which is actually what we need and doesn't affect our local development server.
Adjust the router. Since every react-router uses history package, we need to import it and make some adjustments. First of all, install history package if you don't have it:. This will prepend necessary path and make router work in each environment: local as well as production.
This solution offers a way to deploy your site to a subfolder at any level by using native HTML capabilities without adding environment config everywhere. It definitely worked for me and if did or didn't for you, leave your comment below. Happy coding!

Most of the magic of Create React App is done by installing react-scripts and adding it to package. Next part was to peak into one of my Create React App projects and see what it had added to the scripts section in package. As you can see in the above html it adds an element with id rootmy previous app had an element with id app. I could change the id in the html but I changed document. That's it! Running npm start and npm build now runs the react-scripts and can build and serve the project perfectly.
This project didn't have any tests, if you have run of the mill jest tests and your test files are suffixed with. Dependencies Most of the magic of Create React App is done by installing react-scripts and adding it to package. So I started by installing it to my old project: npm install --save-dev react-scripts NPM scripts Next part was to peak into one of my Create React App projects and see what it had added to the scripts section in package.
This value is the final path you can reference in your code, e. To reduce the number of requests to the server, importing images that are less than 10, bytes returns a data URI instead of a path.
This applies to the following file extensions: bmp, gif, jpg, jpeg, and png. SVG files are excluded due to This ensures that when the project is built, webpack will correctly move the images into the build folder, and provide us with correct paths.
One way to add SVG files was described in the section above. You can also import SVGs directly as React components. You can use either of the two approaches. In your code it would look like this:. This is handy if you don't want to load SVG as a separate file. Don't forget the curly braces in the import!
Use this prop to add an accessible title to your svg component. Docs Help GitHub. Create React App. With webpack, using static assets like images and fonts works similarly to CSS. Here is an example: import React from 'react'.

Not only optimization benefits but a plethora lot of goodies:. Service Workers is a type of Worker that lets us run scripts in the background of our browser. It is like a man-in-the-middle between our browser and the network.
The main work of Service workers is to help us cache and serve the cached files which provide an uninterrupted user experience. But service workers have changed the game, with service workers we can cache our website pages not only web pages but other resources that do make up our web pages apart from the text. Service workers cache webpage resources in a new storage called CacheStorage, when we go offline the service workers kick in and serve the cached pages in the CacheStorage.
We understood how service workers workes in the above section. Unlike traditional applications, progressive web apps are a hybrid of regular web pages or websites and a mobile application.
Using the Public Folder
This new application model attempts to combine features offered by most modern browsers with the benefits of mobile experience. Most of the PWA features are not yet supported in most browsers and more features will be added in the future. You see, you keep progressing as more features are added to your browser without a total halt and waiting for your browser to fully support all the PWA features.
In this post, we will learn how to build a PWA in React. Bit encapsulates components in your projects with all their files and dependencies, so they can run anywhere across your applications.
Build faster by making your components reusable out-of-the-box, and collaborate as a team to share and discover components. No refactoring or configurations needed, just share components and build truly modular apps.
We can create our own SPA app using React. We will scaffold our React using create-react-app. If you don't have it installed globally in your system, run this command:. Next, we create a React app. The following files are created in your react-app folder.JSON Crash Course
The manifest. You can hide the address bar and the Chrome browser to make the app look native, make the app go fullscreen, run on its own window. It will be replaced with the URL of the public folder during the build. Only files inside the public folder can be referenced from the HTML.
