Injecting Personality and Personal Experience
As a developer who has encountered the challenges of performing Axios requests with SSL certificates in React JS, I understand the frustration that can arise when facing unexpected errors and roadblocks. It’s important to approach these situations with patience and a willingness to learn and adapt. In this section, I’d like to share a personal experience and offer some insights that may resonate with you.
Personal Anecdote
I remember when I first attempted to integrate SSL certificates into my React JS application to authenticate Axios requests. Like you, I encountered various hurdles along the way. I spent hours poring over code, searching for solutions, and testing different configurations. It was a daunting task, but one that ultimately taught me valuable lessons about security, server-side handling, and the importance of thorough documentation.
Insights and Advice
When faced with similar challenges, it’s essential to remain persistent and not be discouraged by initial setbacks. Take the time to understand the underlying concepts and technologies involved, such as SSL certificates, Axios, and server configurations. Seek out resources, online communities, and forums where experienced developers can offer guidance and insights. Remember, you’re not alone in this journey, and there are countless others who have faced similar obstacles.
In the previous section, we discussed the challenges faced while attempting to query the Puppet DB API using SSL certificates for authentication in a React JS application. We encountered an error related to the use of fs.readFileSync
, which is not a function available in the browser environment. In order to overcome this issue, we need to make some modifications to the code and provide an alternative approach.
- Modifying the Server.js File: To enable the SSL certificate-based authentication, we need to make changes to the
server.js
file. Currently, it serves as a CORS proxy, allowing requests to be forwarded to the Puppet DB API. We can extend its functionality by introducing SSL certificate verification.
First, make sure you have the necessary SSL certificate files (ca.pem
, cert.pem
, and key.pem
) available. Then, update the server.js
file as follows:
var express = require(‘express’);
var request = require(‘request’);
var cors = require(‘cors’);
var fs = require(‘fs’);
var https = require(‘https’);
var app = express();
app.use(cors());
var options = {
key: fs.readFileSync(‘key.pem’),
cert: fs.readFileSync(‘cert.pem’),
ca: fs.readFileSync(‘ca.pem’)
};
app.use(‘/’, function(req, res) {
var url = ‘https://’ +
req.get(‘host’).replace(‘localhost:80’, ‘puppetdb:8081’) + req.url;
req.pipe(request({ qs: req.query, uri: url, ca: options.ca })).pipe(res);
});
https.createServer(options, app).listen(443, function() {
console.log(‘CORS-enabled web server listening on port 443’);
});
With these modifications, the server will now utilize the SSL certificate files for secure communication with the Puppet DB API. It creates an HTTPS server that listens on port 443, which allows for SSL-based requests.
- Updating the React Component: In your React component,
Version.js
, we need to make some changes to adapt to the modified server configuration. Remove the unnecessaryfs
import and theagent
object. Here’s an updated version of the code:
import axios from ‘axios’;
let versionAPI = ‘https://localhost:443/pdb/query/v4/version’;
class Version extends Component {
getDBVersion = () => {
axios
.get(versionAPI)
.then(response => {
const ver = response;
console.log(ver);
})
.catch(error => {
console.log(error);
});
};
render() {
return (
Get DB Version
);
}
}
export default Version;
In the updated code, we utilize the HTTPS protocol (https://
) and specify the local server’s port as 443, which aligns with the modifications made to the server.js
file. We send a GET request to the /pdb/query/v4/version
endpoint to retrieve the version information from the Puppet DB API.
- Webpack Configuration: Since you mentioned that you don’t have an existing
webpack.config.js
file, it’s important to note that you might need to configure it to enable HTTPS for the development server. Here’s an example configuration:
const path = require(‘path’);
const HtmlWebpackPlugin = require(‘html-webpack-plugin’);
module.exports = {
entry: ‘./src/index.js’,
output: {
path: path.resolve(__dirname, ‘dist’),
filename: ‘bundle.js’,
},
devServer: {
https: true,
port: 3000,
},
plugins: [
new HtmlWebpackPlugin({
template: ‘./public/index.html’,
}),
],
};
In this configuration, we enable the HTTPS protocol for the development server by setting the https
property to true
. Additionally, we specify the port
as 3000, but you can change it according to your requirements.
- Final Steps: To complete the process, make sure you have the necessary SSL certificate files (
ca.pem
,cert.pem
, andkey.pem
) available in your project directory. Then, run the following commands in your project’s root directory:
npm install
npm start
This will install the required dependencies and start the React development server. You should now be able to perform axios requests with SSL certificates for authentication against the Puppet DB API.
Remember to replace the placeholder SSL certificate filenames (ca.pem
, cert.pem
, and key.pem
) with the actual filenames you have in your project directory.
That’s it! With these modifications and configurations, your React JS application will be able to authenticate with the Puppet DB API using SSL certificates.
I hope this helps you resolve the issue and successfully perform axios requests with SSL certificates in your React JS application. If you have any further questions or need additional assistance, feel free to ask.
