So i'm using the Contentful API to get some content from my account and display it in my Next.Js app (i'm using next 9.4.4). Very basic here. Now to protect my credentials, i'd like to use environment variables (i've never used it before and i'm new to all of this so i'm a little bit losted).
I'm using the following to create the Contentful Client in my index.js file :
const client = require('contentful').createClient({
space: 'MYSPACEID',
accessToken: 'MYACCESSTOKEN',
});
MYSPACEID and MYACCESSTOKEN are hardcoded, so i'd like to put them in an .env file to protect it and don't make it public when deploying on Vercel.
I've created a .env file and filled it like this :
CONTENTFUL_SPACE_ID=MYSPACEID
CONTENTFUL_ACCESS_TOKEN=MYACCESSTOKEN
Of course, MYACCESSTOKEN and MYSPACEID contains the right keys.
Then in my index.js file, i do the following :
const client = require('contentful').createClient({
space: `${process.env.CONTENTFUL_SPACE_ID}`,
accessToken: `${process.env.CONTENTFUL_ACCESS_TOKEN}`,
});
But it doesn't work when i use yarn dev, i get the following console error :
{
sys: { type: 'Error', id: 'NotFound' },
message: 'The resource could not be found.',
requestId: 'c7340a45-a1ef-4171-93de-c606672b65c3'
}
Here is my Homepage and how i retrieve the content from Contentful and pass them as props to my components :
const client = require('contentful').createClient({
space: 'MYSPACEID',
accessToken: 'MYACCESSTOKEN',
});
function Home(props) {
return (
<div>
<Head>
<title>My Page</title>
<link rel="icon" href="/favicon.ico" />
</Head>
<main id="page-home">
<Modal />
<NavTwo />
<Hero item={props.myEntries[0]} />
<Footer />
</main>
</div>
);
}
Home.getInitialProps = async () => {
const myEntries = await client.getEntries({
content_type: 'mycontenttype',
});
return {
myEntries: myEntries.items
};
};
export default Home;
Where do you think my error comes from?
Researching about my issue, i've also tried to understand how api works in next.js as i've read it could be better to create api requests in pages/api/ but i don't understand how to get the content and then pass the response into my pages components like i did here..
Any help would be much appreciated!
EDIT :
So i've fixed this by adding my env variables to my next.config.js like so :
const withSass = require('@zeit/next-sass');
module.exports = withSass({
webpack(config, options) {
const rules = [
{
test: /\.scss$/,
use: [{ loader: 'sass-loader' }],
},
];
return {
...config,
module: { ...config.module, rules: [...config.module.rules, ...rules] },
};
},
env: {
CONTENTFUL_SPACE_ID: process.env.CONTENTFUL_SPACE_ID,
CONTENTFUL_ACCESS_TOKEN: process.env.CONTENTFUL_ACCESS_TOKEN,
},
});

NEXT_PUBLIC is a new feature added. Before, in order to set up environment variables, we had to set up both for server and client. environment variables that are placed in the . env file would be available only on the server-side, if you want to make your env variables available at client-side you had to use next.
Using environment variables is a somewhat common practice during Development but it is actually not a healthy practice to use with Production. While there are several reasons for this, one of the main reasons is that using environment variables can cause unexpected persistence of variable values.
You have to make a simple change in next.config.js
const nextConfig = {
reactStrictMode: true,
env:{
MYACCESSTOKEN : process.env.MYACCESSTOKEN,
MYSPACEID: process.env.MYSPACEID,
}
}
module.exports = nextConfig
change it like this
