Transforms for YAML within Jest
npm install jest-transform-yaml> A Jest transformer that allows the import of YAML files
When you store your data in YAML format for your application, you
might want to import that data within your Jest tests. By default,
Jest does not know how to import YAML files, so you will need to
provide a transformer that can properly load it.
NOTE: I generally recommend saving exact dependencies to avoid
accidental/unintentional updates, hence the added flags below.
``bashNPM
npm install jest-transform-yaml --save-dev
Usage
In your
jest.config.js (or jest.config.ts) file, add
the following:`javascript
module.exports = {
// ...
transform: {
// ... other transforms ...
"\\.yaml$": "jest-transform-yaml",
},
"moduleFileExtensions": [
// .. other file extensions ...
"yaml"
],
// ...
}
``Currently, this is set up to be tested against all Node LTS versions and the current. If you observe an issue within your project around Node version support, please feel free to raise a PR or add an issue :smile:
