示例1: syncFilterExpression
export function syncFilterExpression(
config: Record<string, any>,
filterExpression: string,
fields: string[] = []
) {
let changed = false;
const filterAst = fromExpression(filterExpression);
const newAst = fields.reduce((ast, field) => {
const val = get(ast, `chain[0].arguments.${field}[0]`);
if (val !== config[field]) {
changed = true;
if (!config[field]) {
// remove value if not in expression
return del(ast, `chain.0.arguments.${field}`);
}
return set(ast, `chain.0.arguments.${field}.0`, config[field]);
}
return ast;
}, filterAst);
return { changed, newAst };
}示例2: async
): ExpressionRunner => async (expressionOrAst, { element, context, getInitialContext }) => {
// TODO: make interpreter initialization synchronous to avoid this
const interpreter = await interpreterPromise;
const ast =
typeof expressionOrAst === 'string' ? fromExpression(expressionOrAst) : expressionOrAst;
const response = await interpreter.interpretAst(ast, context || { type: 'null' }, {
getInitialContext: getInitialContext || (() => ({})),
inspectorAdapters: {
// TODO connect real adapters
requests: new RequestAdapter(),
data: new DataAdapter(),
},

onDestroy: fn => {
// TODO implement
},
done: () => {
// TODO implement
},
});
} else {
// eslint-disable-next-line no-console
