Convert HTML and `<canvas>` to SVG using Chromium.
4+
5+
## Usage
6+
7+
### CLI
8+
9+
```shell
10+
$ html2svg http://google.com > google.svg
11+
```
12+
13+
### Server
14+
15+

$ curl -d http://google.com http://localhost:8765 > google.svg
18+
```
19+
20+
## Development
21+
22+
> - Building Chromium for ARM on Linux or Windows is not officially supported, cross-compile from x64 instead.
23+
24+
1. Fetch dependencies:
25+
```shell
26+
$ yarn
27+
```
28+
2. Clone Electron.js and Chromium using `gclient`:
29+
```shell
30+
$ yarn gclient
31+
```
32+
3. Configure the build system using `gn` using one of these commands:
33+
```shell
34+
# for local developement
35+
$ yarn gn testing
36+
# or for releasing
37+
$ yarn gn release
38+
# add --ide=xcode if you'd like to generate an Xcode project on macOS
39+
$ yarn gn release --ide=xcode
40+
```
41+
4. Build using `ninja` using one of these commands:
42+
```shell
43+
# make a testing build
44+
$ yarn ninja testing
45+
# make a release build
46+
$ yarn ninja release
47+
```
