vite-plugin-valibot-env
A Vite plugin to validate environment variables against a Valibot schema.
Why?
It's generally a good idea to check that you're all set up early in the development process. Validating that your environment variables have been defined and are of the expected type is a part of that – for yourself and your colleagues. While there are many libraries to validate against a schema, Valibot stands out for its versatility and modularity. The small footprint makes it an ideal candidate for validation in the frontend. So why not use it in your development process as well?
Installation
npm install -D vite-plugin-valibot-env valibot
Usage
Let's start with a very basic example
import { defineConfig } from 'vite';
import * as v from 'valibot';
import valibot from 'vite-plugin-valibot-env';
const schema = v.object({
VITE_API_ENDPOINT: v.pipe(v.string(), v.url()),
VITE_LOCALE: v.literal('en_US'),
});
export default defineConfig({
plugins: [
valibot(schema),
]
});
[!TIP] You might want to use
loadEnv
in your configuration to load.env
files.
API
valibot(schema, options?)
Options
options.ignoreEnvPrefix
Type: boolean
Default: false
Setting this to true
will also validate unprefixed environment variables.
[!TIP] Vite uses a prefix to prevent leaking all environment variables into your code. The same limitation applies to the validator. However, there might be use cases where you want validate unprefixed environment variables as well, e.g.
HOST
andPORT
to configure the Vite server.
options.transformValues
Type: boolean
Default: false
Setting this to true
will try and transform string values to their respective types. Supports booleans, integers, floats, and null
.
options.language
Type: string
Default: undefined
Language ID for localized error messages.
[!NOTE] When using this option, you need to install
@valibot/i18n
and import it into your Vite config.
options.onBeforeIssues
Type: function
Default: undefined
A callback function executed after any issues have been printed.
options.onAfterIssues
Type: function
Default: undefined
A callback function executed after all issues have been printed.
[!TIP] You could use this to point collaborators to the documentation of your project's environment variables.
options.throwError
Type: boolean
Default: false
[!CAUTION] This option exists for testing purposes and is not recommended for use.
Throws an error rather than exiting gracefully when issues have been found in the schema.
