A node.js dynamic map tile server that can connect to ODBC connections, with CartoCSS styling

windwalker's Issues

Locking cache for render

Use a locking cache for rendercache.

Setup dev/production environment variable understanding

This will determine rather or not to hide errors by default, user can always override though.
Look at standard if its normal to log errors or not with env variable, don't want to confuse people that it acts one way in dev and not the same way in production, with the exception of maybe security concerns (showing errors as a tile response)

Get rid of hard requirement for Mapnik VS2015 RC

Currently need to get Mapnik VC2015 for MySQL plugin to work and OGR datasources

VS2015 RC vcredist here: https://www.microsoft.com/en-us/download/details.aspx?id=46881

Get the mapnik build here: https://mapnik.s3.amazonaws.com/dist/dev/vs2015rc1/node-v14-win32-x64.tar.gz

Extract node-v14-win32-x64.tar.gz into Windshaft\node_modules\tilelive-mapnik\node_modules\mapnik\lib\binding

Investigate sql templates

See if windwalker exposes bbox token functionailty explaind here https://github.com/mapnik/mapnik/wiki/PostGIS. Also suggest it as a feature to mssql-mapnik if its not one.

Remove geom_type

I believe geom_type can be deferred and or not needed.

Enable vector tiles

Allow for vector tiles to be rendered

Allow mapnik 3.0 text symbolizer features

https://github.com/mapnik/mapnik/wiki/TextSymbolizer

• margin
• repeat-distance

Allow non-database datasources to have custom styles

Reuse as much of grainstore as possible o allow allow non-database datasources to go through grainstore. Would be able to provide a remote zipped shape file and supply a .mss style without having to create a mml file.

This required mml file support first

More msssql plugin support parameters

Try to support parameters such as wkb from https://github.com/gaspardle/mapnik-mssql

format from URL

Make sure format from URL is working correctly and investigate all possibilities and make sure they are valid. Throw an error for bad formats. Also if format is supplied then take it as an override despite the request extention.

Consider json and js too for utfgrids

Fix nodejs package name to be lowercase

Windwalker to windwalker

Update Grainstore

Look into using https://github.com/mapnik/mapnik-reference/ and see what other forks of grainstore have done. https://github.com/wsw0108/talkstore has some code that could be useful.

Return 204 no content for empty tiles

Return HTTP header 204 with no payload when mapnik has no data for the tile. This in turn should/can be taken advantage of for user interface map libraries not to request a utf grid for that tile.

Requests for grids returns valid json with no data

Currently tilelive-mapnik will throw an error, which windshaft intercepts and doesnt give a json. Unit tests prefer valid jason when a request is made, but without data. Not sure which one is better at this time.

Allow for templated request sql

Instead of taking the SQL sent as a request as a brand new sql, assume it is a wrapper to the existing SQL and allow queries like SELECT TOP 10 * FROM %TABLE% where %TABLE% is the subquery of the original SQL.

Error handling

Allow them to specify error handling via express and improve the log errors and error trace to use object

ODBC and database auto detect

Make sure ODBC connections will correctly get put into the mapnik xml. Default mssql to ODBC and possibly add support for additional mapnik datasource/connections via plugins to Windwalker. For example using mssql-mapnik would be a simply nodejs package that windwalker would automatically know how to inject the input file where they need it.

Start off with ODBC and mssql and then include from a huge list of possible mapnik plugins that can be used.

Remove underscore

Remove underscore in favor of lodash. Make sure all underscore functions are working properly with lodash.

add marker-placement

Modify grainstore/carto/millstone to allow for marker-placement

Allow MML files to be provided

Use millistone to be able to take in a .mml file.

I don't think modifying grainstore is worth while, instead make a wrapper including grainstore that encompasses all 3 inputs (grainstore/mml (millstone)/xml)

• Take in local mml file with local datasource
• Take in local mml file with remote datasource
• Take in local mml file with remote zipped datasource
• Take in remote mml file and treat it like a local mml file

Update to grainstore 1.3.x

https://github.com/CartoDB/grainstore

Getting 'TypeError: cannot access 'dbname' of undefined while running examples\server.js and using examples\viewer\index.html

Hi i tried to install windwalker on windows server 2012 with the node installer you uploaded but i keep getting this error

Combine res._headers and headers

Two places that have headers in the event functions, but they get merge to one place res._headers -- consider just one place

Better and indepth readme

replace minzoom and maxzoom

'maxzoom' is deprecated and will be removed in Mapnik 4.x, use 'maximum-scale-denominator'

Modify grainstore/carto/millstone as needed.

Upgrade to express 4.0

Upgrade to express 4.0 and write new tests.
