S… Speaker 1 (145. Configuring the Handling of Query Parameters)

So in the last lecture,

0:03

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

we tried to improve our application a bit more,

0:05

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

but the issue is our query parameters are gone whenever we

0:09

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

navigate away from our single server component to the added server component,

0:13

S… Speaker 2 (145. Configuring the Handling of Query Parameters)

for example.

0:14

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

So we want to preserve them because we already set this

0:18

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

information at the point of time we visit a single server.

0:21

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

Now we want to preserve this information once we navigate one step further

0:26

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

to the added server component.

0:28

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

To preserve that information,

0:30

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

we get a simple way of doing so.

0:32

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

In the server component where we navigate,

0:34

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

we can pass another property or add another

0:38

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

property to this JavaScript object we use to configure our

0:43

S… Speaker 2 (145. Configuring the Handling of Query Parameters)

navigation.

0:43

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

And here we get the query params handling

0:47

S… Speaker 2 (145. Configuring the Handling of Query Parameters)

property.

0:49

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

Now query params handling takes a string as a value

0:53

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

and this could be merge to merge our old query

0:57

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

params with any new we might add here.

0:59

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

Now we don't add any new ones,

1:02

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

so we can simply choose preserve instead and

1:06

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

preserve, which will overwrite the default behavior,

1:08

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

which is to simply drop them.

1:11

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

and make sure that the old ones are kept.

1:13

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

Now if we were to add new ones here,

1:16

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

the old ones would actually overwrite the new ones,

1:18

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

so we should use merge in this case.

1:20

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

But since we don't add new ones,

1:22

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

preserve should make sure that we don't lose them.

1:25

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

So now if you click on this again and click edit server,

1:29

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

now you see allowEdit equal to zero is still set.

1:33

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

And therefore on the dev server,

1:35

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

where it is set to 1 if we click edit server,

1:37

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

we do see the edit menu again.

1:39

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

So query params handling here,

1:42

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

super important,

1:43

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

super useful to know,

1:44

S… Speaker 1 (145. Configuring the Handling of Query Parameters)

to make sure you don't lease the information you had before.
