Example of calling an external API to generate and store a color
var url = "http://www.colr.org/json/color/random";
request(url, function (error, response, body) {
if (!error && response.statusCode == 200) {
var obj = JSON.parse(body);
if(obj.colors[0].tags[0].name){
bgColor = obj.colors[0].hex;
res.render("global/index", {color:obj.colors, bgColor : bgColor});
}
if (obj.colors[0].tags[0].name === 'undefined'){
bgColor = "999";
res.send("something went wrong :(")
}
}
if(error){
res.send("Error :(")
}
});
- If you need a color when adding an object to the database
- Assign the generated color to a color varaible and add that
Example: var color; var url = "http://www.colr.org/json/color/random";
request(url, function (error, response, body) {
if (!error && response.statusCode == 200) {
var obj = JSON.parse(body);
if(obj.colors[0].tags[0].name){
color = obj.colors[0].hex;
return color;
}
}
});
You now have a color variable. If your user model looked like this:
USER |- name |- email |- age |- password |- color
