# Upgrade Migration
Compared to AIoT-toolkit1.0, AIoT-toolkit2.0 has significantly improved the compilation speed of the Xiaomi Vela JS
project, while also bringing some breaking changes. When an old project uses 1.0 and is preparing to upgrade to 2.0, please follow the precautions below to make minor modifications to the source code.
# Precautions
Developers upgrading from AIoT-toolkit1.0 to AIoT-toolkit2.0 should pay attention to the following:
Description | Solution |
---|---|
Some syntax corrections 1. No need to nest {{}} inside {{}} , change onclick="{{fun({{x}},{{y}})}} " to onclick="fun(x, y)" 2. Unsupported style selectors will report errors, such as pseudo-classes | Modify the source code |
Dynamic paths are not converted to full paths: 1.0 syntax: ../../common 2.0 syntax: /common/**** | Modify the source code |
There are also some special dynamic CSS values that need to use new syntax when upgrading from AIoT-toolkit1.0 to AIoT-toolkit2.0:
- transform
this.divStyle = {
transform: JSON.stringify({
translateX: "10px",
translateY: "20px",
scaleX: 2,
scaleY: 0.5,
rotate: "10deg",
}),
};
background
// Linear gradient this.divStyle = { background: JSON.stringify({ values: [ { type: "linearGradient", directions: ["to", "left"], values: ["#FF0000 10px", "#0000FF 100%"], }, ], }), }; // Radial gradient this.divStyle = { background: JSON.stringify({ values: [{ type: "radialGradient", size: ["farthest-corner"], directions: ["center"], values: ["#3f87a6", "#ebf8e1", "#f69d3c"], }], }), };
filter
this.divStyle = {
filter: JSON.stringify({
blur: "10px",
}),
};
- url
this.divStyle = {
backgroundImage: "/common/logo.png",
};
Note
Please be sure to make the modifications according to the instructions in the precautions, otherwise, it will affect the normal operation and startup of the project after upgrading to 2.0.
