ionic vue use .env

How to Use .env with Ionic Vue#

If you are building an application with Ionic Vue, you may want to use environment variables to store sensitive information such as API keys, database credentials, etc. One way to achieve this is by using a .env file.

Step 1: Install the dotenv package#

To use a .env file in your Ionic Vue project, you need to install the dotenv package.

npm install dotenv --save-dev

Step 2: Create a .env file#

Next, create a new file in the root of your project called ".env". Inside this file, you can define your environment variables like this:

API_KEY=1234567890
DATABASE_URL=http://localhost:3000

Make sure to replace the values with your actual data.

Step 3: Load the environment variables#

Now that you have created your .env file, you need to load the environment variables into your application. You can do this by adding the following code at the top of your main.js file:

import dotenv from 'dotenv'
dotenv.config()

This will load the environment variables from the .env file and add them to the process.env object.

Step 4: Use the environment variables in your code#

You can now use the environment variables in your code by accessing them through the process.env object. For example, to access the API_KEY variable, you can use:

const apiKey = process.env.API_KEY

Or, to access the DATABASE_URL variable:

const dbUrl = process.env.DATABASE_URL

Alternative: Use vue-cli-plugin-dotenv#

If you are using the Vue CLI to create your Ionic Vue project, you can use a plugin called vue-cli-plugin-dotenv to load environment variables from a .env file automatically. To install this plugin, run:

vue add dotenv

This will create a new .env file in the root of your project and add the necessary configuration to your vue.config.js file to load the environment variables.

Conclusion#

Using environment variables is a good practice to keep sensitive information out of your codebase. With the dotenv package or the vue-cli-plugin-dotenv plugin, you can easily load environment variables from a .env file in your Ionic Vue project.
