If I render an SVG image with <Image source={{uri: 'https://productpains.com/img/user-placeholder.svg'}} />, nothing renders and I don't get any error message.
This would be great for dynamically rendered SVG.
how? It doesn't support show SVG file (or i couldn't find the way)
@Ilker Güller: SVG is a markup just like HTML, open it in your editor and convert it manually into a JSX file as shown in the examples
this still isn't implemented? weird
TL;DR: I am happy to help provide Sketch generated SVG graphics of single and multi-color icons and help test when this feature gets worked on.
--------------------
Some scenarios I see:
- multiple paths inside a single <PATH>
- separate paths in their own <PATH>
- <PATH> elements inside Groups
- Using Id= to set the name of each <PATH> . (would be ideal to design in black and white and allow color overrides in RN
- Clockwise vs. counter-clockwise SVG paths
it does not look like react-native-svg supports some of these common elements (id, group) that would get set from a designer in Sketch, it's more geared toward generating SVGs programatically.
Vector Icons are not enough i'm afraid. Try using symbols like Cross, Stopwatch, Block, etc. inside a background, where the background must be one color and the icon on top must be another vs. transparent. Icons do not allow this.
Also from a workflow standpoint of designers creating SVG graphics in a popular tool like Sketch, it is VERY CONVOLUTED currently to get those SVGs turned into Icons even with Fontello or Icomoon, etc. I just spent all day yesterday working on this, and we are falling back to the built in PNG support and 1x-3x image sizes.
Attached is a sample 2-color icon as a PNG and below is the code that Sketch generates when outputting to SVG (the white is not transparent)

thank you for the excellent summary on the current state of affairs.
"we are falling back to the built in PNG support and 1x-3x image sizes"
this seems to be the best approach instead of exporting complex svg from sketch and trying to render it with react-native-svg-uri.
I am wondering if exporting from other graphic editors beyond sketch would produce any better svg code?
Overall, i am at a loss on what the current state of SVG support is across react native, native android, and native ios. So I don't even know which rules are not supported in the autogenerated svg files.
use a WebView
does it help with this? https://github.com/necinc/msvgc
I think we'll want to be able to specify the source as either a uri (as in the example) or as data (as used by react-native-svg). This gives us some choice over our performance trade offs based on the vector's complexity.
I'm successfully using: https://github.com/react-native-community/react-native-svg
My process:
1. Clean up SVG in graphics app (Illustrator/Sketch/etc) to set consistent width, height, and make sure the viewBox is "0, 0, W, H"
2. Open SVG in text editor to remove width, height, and any undesired/unnecessary styles
3. Open in https://jakearchibald.github.io/svgomg/ and optimize.
4. Integrate info app by converting SVG tags to component-based SVG tags used in https://github.com/react-native-community/react-native-svg and updating with JS variables such that I can controls dimensions, colors, etc.
5. Use in other components.
For a set of icons, I place them in a single component and pass a "name" property to return the desired SVG:
https://gist.github.com/beausmith/d2b56e6659e08ad0ceb4ae8684fb05d1
@Beau Smith: Is this scaleable? As in, if I had a list with 100 png's rendering vs a list of 100 svg's rendering, which would by defualt have better performance? Thanks :)
@Dan Huey: Use react-native-svg If you need to manipulate nodes, otherwise it's not efficient in speed and memory.
@Beau Smith: THANKS!!!
https://github.com/matc4/react-native-svg-uri seems like a great candidate
@Juan: A more efficient way is to convert the svg files to actual react components, much less overhead than react-native-svg-uri for bundled assets (it also has problems with release builds on android, requires a babel plugin to read the svg as plain text). There exists https://github.com/chrisbull/svg-to-react-native-cli
Or alternatively, if you need to clean up svgs made in illustrator for use with react-native-svg, then you can use my gist: https://gist.github.com/msand/4b37d3ce04246f83cb28fdbfe4716ecc
It converts Illustrator SVG export into cross-platform CSS independent mode. CSS rule and style inlining, group gradients into a definitions tag, remove elements with display set to none, make colors hex. Works with react-native-web react-native-svg and svgs to give cross-platform web and native mobile rendering of any SVG produced in Illustrator.
@Mikael Sand: I agree, I had some issues when deploying so I ended up exporting svg as text from independent js files
I just published a new package that solves this and adds support for remote svg images (local and remote)! Try it and let me know if you find any issues.
@Shiva Nandan: Works! My respects
@Shiva Nandan: This will instanciate an entire WebView for each images. Each WebViews asks for a lot of memory and cpu ressources. So it's really not good for performance at scale, when interfaces may have an hundred of little images and icons to display.
@Yair Behar: How this is good?? It`s terrible
@alex row: I wanted to say "not good". I ommited the "not". Of course this is terrible. I corrected my comment.
I'd love to see native support for this. Webviews and other packages have been clunky, at best.
I can't see any image follow your url
We've had great luck using https://github.com/oblador/react-native-vector-icons and icomoon.io for generating a custom icon font.
@udi: cud u kindly guide me on this, I tried unsuccessfully to generate a custom ttf for my RN app.
