|

|
|
|
||
|
|
> 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
|
||
|
|
```
|
||
|
|
|
||
|
|

### 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: [] }
|
||
|
|
