# @jridgewell/source-map |
|
|
|
> Packages `@jridgewell/trace-mapping` and `@jridgewell/gen-mapping` into the familiar source-map API |
|
|
|
This isn't the full API, but it's the core functionality. This wraps |
|
[@jridgewell/trace-mapping][trace-mapping] and [@jridgewell/gen-mapping][gen-mapping] |
|
implementations. |
|
|
|
## Installation |
|
|
|
```sh |
|
npm install @jridgewell/source-map |
|
``` |
|
|
|
## Usage |
|
|
|
TODO |
|
|
|
### SourceMapConsumer |
|
|
|
```typescript |
|
import { SourceMapConsumer } from '@jridgewell/source-map'; |
|
const smc = new SourceMapConsumer({ |
|
version: 3, |
|
names: ['foo'], |
|
sources: ['input.js'], |
|
mappings: 'AAAAA', |
|
}); |
|
``` |
|
|
|
#### SourceMapConsumer.prototype.originalPositionFor(generatedPosition) |
|
|
|
```typescript |
|
const smc = new SourceMapConsumer(map); |
|
smc.originalPositionFor({ line: 1, column: 0 }); |
|
``` |
|
|
|
### SourceMapGenerator |
|
|
|
```typescript |
|
import { SourceMapGenerator } from '@jridgewell/source-map'; |
|
const smg = new SourceMapGenerator({ |
|
file: 'output.js', |
|
sourceRoot: 'https://example.com/', |
|
}); |
|
``` |
|
|
|
#### SourceMapGenerator.prototype.addMapping(mapping) |
|
|
|
```typescript |
|
const smg = new SourceMapGenerator(); |
|
smg.addMapping({ |
|
generated: { line: 1, column: 0 }, |
|
source: 'input.js', |
|
original: { line: 1, column: 0 }, |
|
name: 'foo', |
|
}); |
|
``` |
|
|
|
#### SourceMapGenerator.prototype.setSourceContent(sourceFile, sourceContent) |
|
|
|
```typescript |
|
const smg = new SourceMapGenerator(); |
|
smg.setSourceContent('input.js', 'foobar'); |
|
``` |
|
|
|
#### SourceMapGenerator.prototype.toJSON() |
|
|
|
```typescript |
|
const smg = new SourceMapGenerator(); |
|
smg.toJSON(); // { version: 3, names: [], sources: [], mappings: '' } |
|
``` |
|
|
|
#### SourceMapGenerator.prototype.toDecodedMap() |
|
|
|
```typescript |
|
const smg = new SourceMapGenerator(); |
|
smg.toDecodedMap(); // { version: 3, names: [], sources: [], mappings: [] } |
|
``` |
