Go Panda

Go package that scrapes the interwebs for images of pandas and emails them and stores in a database for future fetching. If you're here to see today's Panda, the website is https://daily-panda.herokuapp.com.

The other repos are:

• Lambda function - https://github.com/OpeOnikute/go-panda-lambda
• Website - https://github.com/OpeOnikute/go-panda-site

How to use

• Run go get github.com/opeonikute/panda

• To fetch a panda image, save it to your cloudinary and mongo database:

    import "github.com/opeonikute/panda"

	goPanda := panda.GoPanda{
		Config: panda.Settings{
			MgDomain:       os.Getenv("MG_DOMAIN"),
			MgKey:          os.Getenv("MG_API_KEY"),
			MailRecipients: os.Getenv("MAIL_RECIPIENT"),
			CdCloudName:    os.Getenv("CD_CLOUD_NAME"),
			CdUploadPreset: os.Getenv("CD_UPLOAD_PRESET"),
			MongoURL:       os.Getenv("MONGO_URL"),
			MongoDB:        os.Getenv("MONGO_DATABASE"),
		},
	}
	res, err = goPanda.Run(0)

    if err != nil {
		log.Fatal(err)
	}

    fmt.Println(res)

• To get today's panda (from your Mongo Database0)

    import "github.com/opeonikute/panda"
    
    goPanda := panda.GoPanda{
