This is WebApp project for a Movie Search Exercise, developed using Facebook's library React.js. All data is provided by TheMovieDB API.
The project has been built using node.js v12.15. Make sure your node version is >= v12.15 before you install the packages. Once node is installed. In the project directory, run:
npm install
This installs all the npm dependencies for the project.
This project was bootstrapped with Create React App.
In the project directory, you can run:
Runs the app in the development mode.
Open http://localhost:3000 to view it in the browser.
The page will reload if you make edits.
You will also see any lint errors in the console.
Launches the test runner in the interactive watch mode.
See the section about running tests for more information.
Builds the app for production to the build
folder.
It correctly bundles React in production mode and optimizes the build for the best performance.
The build is minified and the filenames include the hashes.
Your app is ready to be deployed!
See the section about deployment for more information.
Your project can consume variables declared in your environment as if they were declared locally in your JS files. By default you will have NODE_ENV
defined for you, and any other environment variables starting with REACT_APP_
.
The environment variables are embedded during the build time. Since Create React App produces a static HTML/CSS/JS bundle, it can’t possibly read them at runtime. To read them at runtime, you would need to load HTML into memory on the server and replace placeholders in runtime, just like described here. Alternatively you can rebuild the app on the server anytime you change them.
These environment variables will be defined for you on process.env
. For example, having an environment
variable named REACT_APP_SECRET_CODE
will be exposed in your JS as process.env.REACT_APP_SECRET_CODE
.
There is also a special built-in environment variable called NODE_ENV
. You can read it from process.env.NODE_ENV
. When you run npm start
, it is always equal to 'development'
, when you run npm test
it is always equal to 'test'
, and when you run npm run build
to make a production bundle, it is always equal to 'production'
. You cannot override NODE_ENV
manually. This prevents developers from accidentally deploying a slow development build to production.
To define permanent environment variables, create a file called .env
in the root of your project:
REACT_APP_SECRET_CODE=abcdef
Note: You must create custom environment variables beginning with
REACT_APP_
. Any other variables exceptNODE_ENV
will be ignored to avoid accidentally exposing a private key on the machine that could have the same name. Changing any environment variables will require you to restart the development server if it is running.
.env
files should be checked into source control (with the exclusion of .env*.local
).
Note: this feature is available with

and higher.
.env
: Default..env.local
: Local overrides. This file is loaded for all environments except test..env.development
,.env.production
: Environment-specific settings..env.development.local
,.env.production.local
: Local overrides of environment-specific settings.
Files on the left have more priority than files on the right:
npm start
:.env.development.local
,.env.development
,.env.local
,.env
npm run build
:.env.production.local
,.env.production
,.env.local
,.env
Note: this is a one-way operation. Once you eject
, you can’t go back!
If you aren’t satisfied with the build tool and configuration choices, you can eject
at any time. This command will remove the single build dependency from your project.
Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except eject
will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
You don’t have to ever use eject
. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
