app.put('/trustRoutes/:id/:item', (req, res){
I am able to update the data with a single parameter but since I only want to change one value inside that object, calling put will replace the whole object with my new body.
below is what I've tried.
app.put('/trustRoutes/:id/:item', (req, res) => {
readFile(data => {
const userId = req.params['id/item'];
// have also tried const userId = req.params.id.item
data[userId] = req.body;
//write data back to file
I looked around at other examples but couldn't find any that were updating data instead of GET. If there is one I missed please let me know.
PUT requests are great for completely overwriting a resource, and is idempotent. This answer does a good job explaining idempotency. For updating a resource partially, a PATCH request is a better choice.
app.patch('/trustRoutes/:id/:item', (req, res) => {
readFile(data => {
data[userId] = req.params[id];
data[item] = req.params[item];
// A get request for this resource would now show both of the updated values
// Write file
