Hi! This is just what I was looking for!
Is there a documentation of this API? I wonder how I should go about rendering a piece of a map, with a custom marker and a popup (eventually). Is that possible?

Currently, I do that with Google Static Maps API, to generate this kind of thing:

I've created a little application that generate an image from geoJson data through API. My problem is, even if everything works well on local I cant' make it work on docker container.

Here is the code

require("dotenv").config();
const osmsm = require("osm-static-maps");
const express = require("express");
const app = express();

const fs = require("fs");

app.use(express.json());

app.post("/generateStaticMap", async (req, res) => {
  const { geojson } = req.body;

  const imageBinaryBuffer = await osmsm({ geojson });

  res.send(imageBinaryBuffer.toString("base64"));
});

app.listen(process.env.APP_PORT, () => {
  console.log(`Server is running on port ${process.env.APP_PORT}.`);
});

Here is the docker file

FROM node AS builder
WORKDIR /app
COPY ./package.json ./
RUN npm install
COPY . .

# Second Stage : Setup command to run your app using lightweight node image
FROM node
WORKDIR /app
COPY --from=builder /app ./
RUN \
    apt-get update \
    && \
    apt-get install -y \
    libx11-xcb1 \
    libxtst6 \
    libnss3 \
    libxss1 \
    libasound2 \
    libatk-bridge2.0-0 \
    libgtk-3-0 \
    fonts-wqy-zenhei \
    && \
    rm -rf /var/lib/apt/lists/*

RUN \
    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y \
    && \
    /root/.cargo/bin/cargo install oxipng

CMD ["npm", "run", "start"]

And finally here is the error I get when I try to create an image

{}

    return browser.newPage()
                   ^

Add option to set a different marker icon. Refer to how google static maps api does it.

• see this https://leafletjs.com/reference-1.6.0.html#icon
• and here https://wiki.openstreetmap.org/wiki/Static_map_images#Comparison_Matrix

add option to set the config file, search it on multiple paths by default, also use configs from env variables, document precedence and file paths

Think on how to add a directory/redis/memcache cache so that this can be used as a <img src="..."> tag more efficiently. Maybe add a cache param like

• cache=directory:path
• cache=redis:url
• cache=memcache:url
  and maybe use another param like cache_force_refresh=true to refresh cache, or a timeout like cache_timeout to expire old elements saved in cache

this module looks good enough https://www.npmjs.com/package/cache-manager
and this one to build the key from the options object https://www.npmjs.com/package/json-stable-stringify

Hi, I'm wondering if there is a way to draw circles ?
Thanks for this project!

are PBF/MVT Vector Tile Sources with stylesheets (JSON) supported?

Hiya, this matrix of available services says yours is healthy, but it looks like it's offline.

Thanks for the great library!

But when center parameter is passed to the url, it gives error!
Please check examples
http://osm-static-maps.herokuapp.com/?width=512&height=512&center='0,0'
http://osm-static-maps.herokuapp.com/?width=512&height=512&center=0,0

Regards

Julian, cómo estás? Tengo mi propio servidor de OSM y quiero agregarle esta funcionalidad.

Es eso posible? Tenés algo en lo que me pueda basar?

Muchas gracias!

Saludos,
Federico.

Is it possible to adjust the fill color used to display geojson polygons?

I am getting the following crash when trying to add very large polylines:

code:"E2BIG"
errno:"E2BIG"
error:Error: spawnSync /bin/sh E2BIG
message:"spawnSync /bin/sh E2BIG"
output:null
path:"/bin/sh"
pid:79999
signal:null

Any advice?

I am aware of that

heroku server might be unstable because of too many requests being made to it

but http://osm-static-maps.herokuapp.com/ showing

 Application error

An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command
heroku logs --tail 

looks suspicious to me.

Hi,

I've been watching docker-related files to fix a problem I had (see #19), and it doesn't seem to be "production-ready" IMO.

Here's some issues I see :

• npm install is done when the container is started (instead of when the image is built)
• the container runs nodemon instead of node
• a volume map the entire root folder (to avoid npm install on each docker run I guess)

Also, resolving these issues would allow to push the image on the docker hub, which would come in handy !

If you're interested I can work on a PR to make things better.

The demos are giving an application error.

Im using POST method and I have this error. I insert a json file with the body:
{ "zoom": 12, "height": 673, "width": 1067, "type": "FeatureCollection", "features":[ { "type":"Feature", "properties":{ }, "geometry":{ "type":"Point", "coordinates":[ -45.194978739803766, -22.78995147526845 ] } } ] }

see https://wiki.openstreetmap.org/wiki/Static_map_images#Comparison_Matrix

add option to add a scale to the map like google static maps api does it.

• use https://leafletjs.com/reference-1.6.0.html#control-scale
• do it as a boolean option (default to false)

@jperelli Thanks for this repo. I'm wondering if there is a way customize the styles and colors of the map or use the exported style for mapbox on this?

adding import osmsm from 'osm-static-maps'; causes my application to crash immediately, without any error.

• Receive geojson param and save as file directly (jpg/png/html)
• Receive all other parameters
• Also be able to receive geojson as stdin (check if stdin is being active and use param from there)
• Install binary into filesystem

Is it possible to have a blank background and just return the drawn polyline/markers?
