Web project using Node.js to implement email sending function
With the rapid development of the Internet, email has become one of the important tools for people to communicate. In web development, sometimes we need to implement the function of sending emails, such as registration confirmation emails, password reset emails, etc. As an efficient server-side JavaScript running environment, Node.js can easily implement the email sending function. This article will introduce how to use Node.js to implement a web-based email sending project, and provide specific code examples.
1. Project environment setup
First, we need to install Node.js locally. You can go to the Node.js official website (https://nodejs.org) to download the installation package for the corresponding operating system, and then install it according to the prompts.
Create a project directory locally and use the command line to enter the directory. Then run the following command to initialize the project:
1 |
|
This command will generate a configuration file named "package.json", which is used to manage the project's dependency packages.
After the initialization is completed, we need to install some necessary Node.js modules, including express, nodemailer and body-parser. You can install it with the following command:
1 |
|
These modules are used to create a web server, send emails, and parse the request body of POST requests.
2. Write code
Create a file named "app.js" in the project directory and write The following code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 |
|
In the above code, the necessary modules express, nodemailer and body-parser are first introduced. Then I created an Express application and defined a "/sendmail" route in the "app.js" file to receive POST requests and send emails. The email is sent using the nodemailer module, which is implemented by creating an SMTP transmitter.
Run the following command in the command line to start the Web server:
1 |
|
3. Test the email sending function
Enter "http://localhost:3000" in the browser to enter the Web page. Then you can send an email through the following code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
|
The above code uses the fetch function to send a POST request to the "http://localhost:3000/sendmail" route, and passes the recipient's email address, email subject, and The email body is used as a request parameter.
After running the above code, if the console outputs "Email sent successfully", it means the email was sent successfully.
Summary
This article introduces how to use Node.js to implement a web-based email sending project, and provides specific code examples. Through this project, we can easily implement the email sending function, and can expand and customize it according to our own needs. I hope this article will be helpful to readers who are new to Node.js and web development.
