QUESTION
SparkNotes:
I'm pulling in a crime API to see hotspots. Certain crimes will not be logged with a lat/long, therefore, are not shown up in standard (free) crime apps.
- Lat/Long pins I've overridden to a new lat/long don't show up on first load/or at all. (google-maps-react) (Confirmed lat/long is valid per crimes in near areas.)
- Normal pins that had an existing lat/long show up fine/show up as soon as it loads. (Even though it's all the same array of data.)
- I loop through the blank lat/long and replace the lat/long with a rough lat/long of the area just so it shows up. In my console log I can confirm that I've overriden the blank lat/long.
- I want these records to understand the neighborhoods/potentially avoid moving into a hotspot of specific crimes.
API Normal:
https://data.seattle.gov/resource/tazs-3rd5.json?$limit=20000&$offset=20000&$order=offense_id
Full Use Case (Which doesn't work for at all pins): https://data.seattle.gov/resource/tazs-3rd5.json?crime_against_category=PERSON&mcpp=MAGNOLIA&offense_parent_group=SEX%20OFFENSES
Request for help: Can someone please help on how to get these overridden pins to show up consistently?
Things I've Tried: Force update/having multiple refreshes etc/decreasing async time. Those work for when I put in specific crime report number, but if I search for kidnapping/peeping tom, they will not pull with the rest of the person crimes.
I can confirm that if I just load every crime in that API, the map logs all of them (except the ones I need), It's like a pin per foot of street, but the pins in the categories I need don't show up. (So I don't believe it's a volume issue.)

...ANSWER
Answered 2021-Apr-27 at 03:04It seems that there's a timing issue when importing your places
data from crimedata.js
in the first load of the code. I can see that the places
value is empty [] in the initial run then the loading of your places in your crimedata.js
will follow after some time. You can see this in the console log in my working code.
To handle this, I used state variables to hold the value of the updatedPlaces
data then in componentDidMount
function, I used setTimeOut and set value of updatedPlaces
state variable from the imported places data that is now available.
I then used this state variable as a condition for the markers to load.
Here's the code snippet:
QUESTION
I'm currently attempting to use Chart.js
within my react application but when I go to build my application I'm presented with this error
ANSWER
Answered 2021-Apr-22 at 11:31Chart.js version 3 is not compatible. Change it to ^2.9.4. The same problem as you and I have been solved.
QUESTION
I try to add InfoWindows to the markers of my map (using google-maps-react) but it doesn't work and I don't understand why. The state receives the longitude and latitude data.
...ANSWER
Answered 2021-Mar-04 at 02:04Since you will be clicking the Marker for the InfoWindow to show, you can use the InfoWindow's marker
parameter instead of position
parameter. You also need to use the InfoWindow's visible
parameter and set it to true for it to show. You can check this simple code how I did it(I just used data from json file). Code snippet below:
QUESTION
I have a component (SearchFilter.js) and am using connect
to trigger mapStateToProps
and mapActionsToProps
on export.
Trouble is, mapStateToProps
isn't firing -- no props (neither state nor actions) show up in React DevTools and I can't even console log from inside mapStateToProps
.
I've tried looking at various Stack Overflow threads but they mostly seem to be typos, or the actions themselves not working.
What's more, I've got an almost identical redux setup for another component (Counter.js) that woks perfectly.
I think it could have something to do with how I provide the store/route to components (see App.js below) as React.Provider shows up in React DevTools for the Counter but not SearchFilter.
Here's the SearchFilter component:

QUESTION
I have tried to add google map to my project and everything works good but i have following warning in my console but don't know why and how to fix it.
"Warning: Using UNSAFE_componentWillReceiveProps in strict mode is not recommended and may indicate bugs in your code. See https://reactjs.org/link/unsafe-component-lifecycles for details.
- Move data fetching code or side effects to componentDidUpdate.
- If you're updating state whenever props change, refactor your code to use memoization techniques or move it to static getDerivedStateFromProps. Learn more at: https://reactjs.org/link/derived-state
Please update the following components: Wrapper"
Below is my code:
...ANSWER
Answered 2020-Nov-26 at 16:56It's a problem in the current version of google-maps-react
and React's strict mode. See: https://github.com/fullstackreact/google-maps-react/issues/476
You probably shouldn't disable strict mode, so you'll have to either fix the library yourself or wait for someone to do that, then upgrade.
QUESTION
very new to react. I'm using google-maps-react-api. I have two files. Index.js and MapMarker.js. It loads a few location points with info windows already loaded. I can close the window but when clicking on the marker they do not reopen. My onCLick events do not work as I expect. I want the case to be the markers load and I click them to show info window and then can close the window as well. I've read the docs and issues on Github but can't find the info. Thanks.
...ANSWER
Answered 2020-Nov-24 at 06:17I made a couple of changes in your MapMaker.js from the codesandbox link you provided.
First, I added a state named showingInfoWindow
and assign a value of false
. This will be the state that will indicate if the infowindow will be shown or not.
Then, I added a function named onMarkerClick
which is called everytime the Marker is clicked. This will set the state of showingInfoWindow
to true
.
Next, I put a condition in the return of MapMaker class, which will only show the infowindow when the showingInfoWindow
is set to true
.
Then, I add the onInfoWindowClose
function that sets the state of showingInfoWindow
back to false
.
Lastly, I added the onCloseClick
parameter in the and call the onInfoWindowClose
function.
You can follow the code snippet below for the changes in MapMaker.js
QUESTION
I am building a full stack MERN (MongoDB Express React Nodejs) application. I am using the NPM package Google Maps React to display google maps on my website. I am having difficulty coming up with a strategy to secure my front end google maps API key.
In order to fully understand my problem it may be helpful to review the Google Maps React component code below
...ANSWER
Answered 2020-Oct-16 at 00:53You have various options to securely store an api key. If you are using CircleCi for continuous builds, you can create an environment key. Check your build solution for something similar.
There are also alternatives for encrypting files such as git-secret. That way you could use an environment config file.
Bottom line do not store keys in code or in config files unless you have it encrypted.
QUESTION
I have array of coordinates, if i add another coordinate in array the route direction of the map should be updated.
this is my code in googlemap.js
...ANSWER
Answered 2020-Sep-25 at 07:46If you have an array of coordinates and would like to show the directions in the map that shows these coordinates, you need to set the first coordinate
as your start
, the last coordinate
as the destination
and the coordinates in between
to be your waypoints
.
Then once you will add a new coordinate in the array, you need to include the previous last coordinate in your waypoint and make the newly added coordinate as the destination.
Here is a sample code that shows this where I use Google Place Autocomplete where you can input a place and it will provide suggestion then once you choose a place from the suggestion it will get it's coordinate andpush the coordinate in the array.
Please see the code snippet below:
QUESTION
I have this react app I want to dockerize. But the problem is, even though I tried, it doesn't work. But it works pretty well locally
This is how the current directories look like:
...ANSWER
Answered 2020-Sep-18 at 09:09Firstly, make sure you are copying the same package-lock.json file that you use to install deps locally, to make sure you have the same dependency tree in your container as you do locally.
COPY package.json package-lock.json /app/
Then, make sure that you are matching the same node/npm version as you run locally (replace 12 with the major version you are running, be it 10, 12, 14 or whatever):
FROM node:12
Each node version is bundled with a specific npm version (latest 12 version comes with npm 6.14.6), you can find the bundled NPM version int he changelogs, https://github.com/nodejs/node/tree/master/doc/changelogs
Additionally, instead of running npm install
, you might wanna run npm ci
in the container. The latter skips any checks for discrepancy between the lock file and your package.json file and just installs the locked dependency tree, which is not only faster, but will also match your local dep tree exactly.
EDIT:
In addition, this line:
COPY . /app
Would also overwrite node_modules unless you have ignored it via .dockerignore or similar.
Easiest would probably be to add a .dockerignore
file to the same folder as your Dockerfile and add lines stating:
QUESTION
I am creating an app that uses wildfire data from APIs and flips it in order to display polygons on a Google Map using the google-maps-react package. I have figured everything out up until returning and displaying the polygon using a function built into the map component. Does anyone want to chime in on what the issue might be? I'd really appreciate some help. Thanks.
...ANSWER
Answered 2020-Sep-09 at 18:24I haven't caught from your comment if you've tried things I've suggested... But you've edited your post with some random (and incorrect) changes. OK, I'll try to post an answer. It's an answer related to the original code because it looks simpler and contains less errors.
